      <abstract>
        <p>This paper focuses on the theme of unlocking the materials preserved by musical institutions such as opera houses, conservatories, and historical archives. In this context, “unlocking” means providing access to anyone, which can be interpreted in two diferent ways. The first meaning, related to openness, implies making preserved materials accessible to a wide audience. From this perspective, digitization campaigns and the subsequent enhancement of cultural assets through technology can open the way to new possibilities. For example, creating a dedicated Web portal can facilitate access by addressing issues such as physical distances, availability at any time of the day, the perishability of physical objects, insurance costs, etc. Moreover, technology can provide new services and foster advanced ways to exploit materials. Concerning the second meaning, related to accessibility, technologies can be used to assist people with physical and cognitive impairments and extend the use of these materials to people for whom it would be more dificult. For example, assistive technologies, such as screen readers or braille displays, allow blind and visually impaired (BVI) users to enjoy the transcription of music or literary texts. Similarly, computer-assisted approaches, such as large language models, can reduce the complexity of a text to meet the communicative abilities of people with special educational needs or cognitive impairments. To better illustrate the meanings of openness and accessibility, we will discuss two scenarios excerpted from the Ricordi Historical Archive. On the one hand, this work aims to highlight the fundamental role of technologies in supporting openness and accessibility, starting from digitization campaigns, through the online publishing of materials, to the release of ad hoc software tools. On the other hand, our research shows that there is still a long way to go before music archives can fully achieve the goals of openness and accessibility.</p>

      <title>1. Introduction</title>
      <p>Music archives hold a wealth of cultural, educational, and research value, preserving the legacy of past
generations and ofering insights into the evolution of societies, institutions, and artistic expressions.
By documenting recordings, sheet music, visual materials, personal papers, instruments, audiovisual
content, publications, and digital resources, music archives respond to the need to preserve musical
heritage for future generations. These archives, often housed within musical institutions such as opera
houses, conservatories, and historical repositories, contain materials that are invaluable to musicians,
scholars, and the general public. Despite their significance, the accessibility of these resources remains
a pressing challenge. Ensuring that a wide and diverse audience can access and benefit from these
materials is fundamental for fostering a deeper appreciation and understanding of cultural heritage.</p>
      <p>In the digital age, technology has emerged as a pivotal tool in overcoming the barriers to accessibility
inherent in traditional archival practices. Digitization campaigns, the creation of online repositories,
and the development of user-friendly software tools can revolutionize the way we interact with archives.
These advancements not only mitigate issues related to physical distance, limited access hours, and the
fragility of physical objects but also open new ways for engaging with archival content. Open access
can democratize the availability of these resources, allowing musicians, researchers, educators, and
curious individuals to explore and use them in innovative ways.</p>
      <p>Moreover, digital technologies ofer significant potential for individuals with physical and cognitive
impairments. Assistive technologies, such as screen readers and braille displays, and adaptations
to simplify complex texts, ensure that archival content is accessible to all, regardless of physical or
cognitive abilities. The dual approach to which we want to direct our work – i.e. broadening access
for a general audience (openness) and catering to the needs of those with disabilities (accessibility) –
underscores the multifaceted role of technology in preserving and disseminating cultural heritage.</p>
      <p>To demonstrate such a role, this paper focuses on two use cases dealing with Giacomo Puccini’s
materials preserved at the Ricordi Historical Archive, specifically a handwritten letter and a score. By
discussing these scenarios, we illustrate the practical implications of digitization and technological
integration in making archival materials available and accessible to diverse audiences. Through this
exploration, we aim to highlight the ongoing eforts and future directions necessary to fully realize the
potential of digital archives in serving as open, inclusive, and widely accessible cultural repositories.</p>
      <p>The remainder of the paper is structured as follows: in Section 2 we will describe the state of the
art on the openness and accessibility of music archives, in Section 3 we will analyze the case studies
inspired by the Ricordi Historical Archive’s collections, in Section 4 we will propose some strategies to
unlock music archives, and, finally, in Section 5 we will draw the conclusion.</p>

      <title>2. Music Archives: Openness and Accessibility</title>
      <sec id="sec-2-1">
        <title>2.1. Definitions of Openness and Accessibility</title>
        <p>
          Openness involves a set of principles and a range of practices through which outputs are publicly
distributed, free of access charges or other barriers [
          <xref ref-type="bibr" rid="ref1">1</xref>
          ]. This fundamental concept promotes the
democratization of information and resources, ensuring that knowledge is freely accessible to all,
irrespective of geographical, economic, or social constraints. At its core, openness is guided by the belief
that knowledge should be a public good, shared openly to foster innovation, education, and cultural
enrichment. The principles of openness advocate for transparency and the unrestricted distribution of
information. By eliminating access charges and other barriers, openness facilitates a more equitable
dissemination of knowledge, enabling individuals and communities worldwide to benefit from and
contribute to the collective pool of human understanding.
        </p>
        <p>Based on the guidelines of W3C 1 Web Accessibility Initiative (WAI)2, resources need to be accessible,
usable, and inclusive, namely they must be easily used by any type of user. In particular, the term
accessible refers to the possibility of guaranteeing equal use to people with or without impairments of
any kind, both physical and cognitive. Everyone must be able to understand, interact, and contribute
equally to Web resources. The term usable is closely linked to User Experience (UX) and User Interface
(UI), which is the interface through which the user enjoys a resource. These aspects must be carefully
designed to ensure an optimal experience for everyone, regardless of their impairment. Finally, the term
inclusive is related to diversity. Diversity is about everyone, without any exclusion. The inclusion
of every nuance must be ensured, from impairments to economic conditions, to every level and type
of education, geographic location, age, culture, language, religion, and preference. In other terms, the
inclusion of every diversity must be granted.</p>
        <p>In this work, we bring to light the aspects of musical archives that require openness, accessibility,
usability, and inclusivity, specifically presenting two case studies inspired by the collections of the
Ricordi Historical Archive. Music archives ofer an interesting field of application due to the nature
of their materials, rare specimens, and unique pieces, whose supports may have aged to the point of
compromising their content before being digitized. Music archives are typically closed, as their content
can be accessed only by experts and scholars and handled through specific equipment. Accessibility is
an even more crucial aspect. In fact, also in the case of digitized materials in good condition, there is
still the need to make them usable and understandable by everyone.

        <title>2.2. Related works</title>
        <p>The scientific literature includes numerous works that, on the one hand, highlight the lack of openness
and accessibility of music archives for people with diferent types of impairments and, on the other,
propose solutions to overcome these shortcomings.</p>
        <p>
          Concerning digitized materials, one aspect to consider and carefully manage is that of metadata,
usually expressed in the form of plain text information. Even if widely adopted to characterize data,
metadata are seldom dedicated to accessibility purposes [
          <xref ref-type="bibr" rid="ref2">2</xref>
          ]. Instead, metadata could be used to let
users with disabilities find resources more easily. Furthermore, metadata can greatly improve the
performances of assistive technologies such as screen readers, as in the case of Semantic HTML and
dedicated markup attributes (title, alt, lang, etc.) [3].
        </p>
        <p>Music archives often contain autograph materials, dificult to read and understand, whose historical
importance is right in the original handwriting. The transcription of handwritten texts is not a simple
activity and often depends on the professional figure of the graphologist. The literature reports on
the technological advances to extract textual content from images, both through Optical Character
Recognition (OCR) [4] and via Handwritten Text Recognition (HRT) [5]. These techniques make
manuscripts readable by text-to-speech systems and screen readers. In this way, text documents are
accessible even to visually impaired people and users who prefer auditory information. The latest
research in this field has also achieved good results in the recognition of cursive writing [ 6]. Music
archives often preserve handwritten documents, e.g. records, contracts, and letters, as demonstrated by
one of the case studies presented below.</p>
        <p>An important category of materials for a music archive is the collection of scores. Once again,
the digitization of images and their transcription into digital format are fundamental activities for
accessibility. The automatic recognition of music symbols, known as Optical Music Recognition (OMR),
poses further challenges [7] compared to OCR due to the complexity and variability of music notation.
Recent advances involve Music Object Recognition (MOR) systems that permit resolving problems
related to manuscript artefacts [8] and end-to-end OMR models to transcribe non-monophonic music
scores [9].</p>
        <p>Another accessibility issue concerns the retrieval and listening of archival audio collections [10, 11, 12].
Here, the demand for open access often conflicts with ownership rights. Some institutions, such as
the Italian national audio record library,3 have the mission of preserving and granting access to sound
documents and equipment; in other cases, such as at Teatro alla Scala, the audio archive is only one
of many specialized archives. Please note that an audio document, intended here as an alternative
rendition of a score, can represent a helping tool not only for BVI people but also for those who do not
have the possibility or the ability to read music.</p>
        <p>As mentioned before, the heterogeneity of the materials typically preserved in a music archive is
huge: scores, audio and video recordings, photographs of performances and artists, posters, librettos,
metadata referring to chronologies and casts, etc. In the case of an institution also involved in music
production, e.g. an opera house, additional items such as stage props, maps, costumes and accessories,
and wigs should be included. The complete openness and accessibility of such an archive necessarily
involves the openness and accessibility of each of its components.</p>
        <p>In [13], the author suggests five milestones on the road toward archival accessibility: 1. creating or
acquiring and accessioning important collections, 2. processing the collections for complete accessibility
in house, 3. describing collections online, 4. producing detailed finding aids on the Web, and 5. making
archival collections themselves available on the Web. Although many music archives are on the right
track, these recommendations assume the involvement and action of many diferent stakeholders, with
diferent interests, which make it dificult to achieve these objectives.

      <title>3. Scenarios</title>
      <p>To exemplify the issues and potentials related to music archives’ openness and accessibility, we will
discuss two scenarios, both inspired by the Ricordi Historical Archive.4 This Italian institution owns and
preserves the original handwritten scores of 23 out of Giuseppe Verdi’s 28 operas, all operas by Giacomo
Puccini (except La Rondine), and numerous works by composers such as Vincenzo Bellini, Gioachino
Rossini, Gaetano Donizetti and, more recently, Luigi Nono, Franco Donatoni, Salvatore Sciarrino, and
Sylvano Bussotti. The great significance of the archive lies in the diversity of its materials, which ofer
an articulated view of the Italian culture, industry, and society. This archive preserves an extensive
collection of visual materials associated with numerous premieres worldwide and locally, encompassing
set and costume designs, photographs, correspondence, and business records.</p>
      <p>The collection covers various artistic domains such as painting, stage design, and decorative arts,
ofering insights into costume history, jewelry design, stage properties, and the broader publishing
landscape. The archive preserves approximately 8,000 scores, more than 16,000 letters exchanged among
musicians, librettists, singers and other stakeholders, approximately 10,000 set and costume designs,
more than 9,000 librettos, 6,000 historical photographs, and a substantial collection of Art Nouveau
and Art Deco posters crafted by prominent artists of the era. Such an articulated scenario allows us to
reflect on the themes of openness and accessibility in relation to the heterogeneity of materials typically
preserved in a music archive (musical scores, monographs, iconographic materials, photographs, stage
props, etc.).</p>
      <p>Visual materials are publicly available on Internet Culturale 5 the Web portal of the Italian National
Library Service that provides a common access point for digital resources and catalogs of Italian libraries,
archives, and cultural institutions. The portal, opened in 2005, aims to make catalogs and part of the
information contained in public libraries available via the Internet. Digital reproductions accessible
from Internet Culturale are mostly in the public domain and come from digitization activities carried
out by libraries that are institutional partners of the portal. These libraries are the owners of both the
originals and their digital reproductions.</p>
      <sec id="sec-3-1">
        <title>3.1. Scenario 1: Handwritten Letters</title>
        <p>The first scenario focuses on the letters and letter copies preserved in the archive. Even if this case
may recall that of generic handwritten texts, please note that this kind of material can contain musical
content as well, e.g. a draft of a musical theme or corrections made to certain passages of a music work.</p>
        <p>The collection of autograph letters, about 15,000 in total, covers the time interval from the early 19th
to the late 20th century. These letters were exchanged between Ricordi and writers, singers, and authors.
These include composers such as Giuseppe Verdi, Giacomo Puccini, Franz Liszt, Ottorino Respighi, Jules
Massenet, Alfredo Casella, and Luigi Nono; librettists such as Luigi Illica, Giuseppe Giacosa, and Arrigo
Boito; renowned singers such as Teresa Stolz, Maria Waldmann, and Victor Maurel. In addition, there
are extensive collections of handwritten or typed letters from the 20th century involving important
Italian cultural figures, such as Gian Francesco Malipiero and Ildebrando Pizzetti.</p>
        <p>On the one hand, specialized experts (e.g., musicologists, historians, sociologists, etc.) are interested
in reading correspondence as it can shed light on the artistic, social, economic, and even personal aspects
of the individuals involved. On the other hand, it would be important to grant access to these sources
to all interested people, including impaired individuals and economically or culturally disadvantaged
people, so as to bring a new audience closer to archival materials.</p>
        <p>Unfortunately, these documents present numerous critical issues related to accessibility. Being objects
of invaluable importance, it is paramount to protect them and preserve their physical integrity. In the
case of the Ricordi Historical Archive, these items are physically stored in a vault, and access is possible
only by appointment and reaching the archive’s headquarters in Milan. In addition, the paper and ink
4Archivio Storico Ricordi, https://www.archivioricordi.com/
5Internet Culturale, https://www.internetculturale.it/
in use were not originally intended for long-term preservation; consequently, physical handling must
be limited as far as possible.</p>
        <p>After solving the first category of problems, i.e. obtaining access to materials, also their
readability can pose critical issues. For example, handwritten signs can make content dificult to read. As
a noticeable example, we take into account Giacomo Puccini’s handwriting style. Fig. 1 shows a
letter sent by the composer from Viareggio, Italy to the publisher Tito (II) Ricordi on July 17, 1913.
The letter is publicly available at https://www.internetculturale.it/jmms/iccuviewer/iccu.jsp?id=oai%
3Awww.internetculturale.sbn.it%2FTeca%3A20%3ANT0000%3AMI0285_PUCCINII-056. Interpreting
the graphical sign, even for a native Italian speaker, is not straightforward. The transcription, courtesy
of the Ricordi Historical Archive, is:</p>
        <p>Caro Tito - che n’è di te? io lavoro. di Tristan - nulla per ora - Vaucaire mi ha mandato uno
schema che non va - pur essendo prolisso - mi si dice che la Cines farebbe oltre altro anche
qualcosa di mio - visto ieri Costa che per Pierrot fissò 30.000 fr.! desidererei (ed è giusto)
sapere come e cosa tu combini - Scrivimi</p>
        <p>Ciao tuo Giacomo Pucci[ni]
and a possible translation into English is:</p>
        <p>Dear Tito, what’s up with you? I am working. From Tristan, nothing for now. Vaucaire sent
me a draft that is not good, despite being verbose. I am told that Cines would do something
of mine in addition to other things. Yesterday I saw Costa who settled on 30,000 francs for
Pierrot! I would like to know (and it’s right) how and what you are doing. Write to me.</p>
        <p>Ciao, your Giacomo Pucci[ni]</p>
        <p>The letter mentions Tristan Bernard, whom the composer approached for the completion of his
project of a triptych. Puccini had already composed one opera out of three, namely “Il tabarro”. Bernard
proposed a fairy tale as the subject for another part, but the project was abandoned since Puccini chose
the one-act operas “Suor Angelica” and “Gianni Schicchi” by Giovacchino Forzano to complete the
triptych. Maurice Vaucaire was a playwright, poet, and librettist who worked on the French translations
of Puccini’s “Manon Lescaut” and “La Fille du Far West”. Finally, the letter mentions “Histoire d’un
Pierrot”, a silent film directed by Baldassarre Negroni, released in 1914, distributed by Cines, with music
by Mario Pasquale Costa.</p>
        <p>This short explanation of the semantic content highlights two additional problems falling in the
category of text accessibility. First, the language in use can be diferent from the current one, even for a
native speaker. Luckily, this is not the case with the letter under exam. Secondly, the full comprehension
of the text requires an in-depth knowledge of the context: the references to other people (Tristan,
Vaucaire, Costa), entities (Cines), and other works (Pierrot), and the use of abbreviations as well (fr. for
francs), make the interpretation of the message quite cryptic.</p>
        <p>Nevertheless, it is evident how a few lines of text can provide valuable information about the contacts
between Puccini and other intellectuals, the journey of the composer’s works, and even economic and
ifnancial aspects, ofering a glimpse into the cultural climate of the time. Furthermore, beyond their
content, letters allow for an investigation into the character and inclinations of the writer and to deepen
the understanding of the relationship between the correspondents.</p>
        <p>A special mention should be made of the limitations concerning search and indexing of paper
documents. For instance, finding all the letters in the archive where Puccini mentions a colleague or
discusses the payment for an opera would require a deep knowledge of all the preserved materials. The
use of metadata, mentioned in Subsection 2.2, would help in this context.</p>
      </sec>
      <sec id="sec-3-2">
        <title>3.2. Scenario 2: Scores</title>
        <p>The second scenario concerns the openness and accessibility of scores. Many of the issues regarding
physical access to materials have already been mentioned in the previous section. Examining the
autograph scores of Verdi or Puccini in person is not an option available to the average visitor. Being
cultural assets of immeasurable value and made of perishable materials, it is necessary to limit physical
access to these objects as much as possible. Indeed, the autograph scores are shown to the public only
during exhibitions and events, well protected by glass cases, allowing only the open pages to be seen.</p>
        <p>But symbolic information is also critical in terms of accessible representation of content. Let us
mention the challenges for blind and partially sighted musicians. For individuals seeking physical copies
of accessible scores, there are two primary options: large print (also called Modified Stave Notation or
MSN) [14] and braille music [15]. The former ofers a customizable format particularly beneficial for
partially sighted musicians, facilitating adjustments such as resizing specific notation elements and
modifying spacing, layout, and line thickness. In contrast, braille music, an extension of the braille
literary code, serves as a viable option for blind musicians. Unfortunately, these solutions are not
directly applicable to a traditional music archive, whose purpose is mainly to preserve cultural heritage
in its original form.</p>
        <p>Autograph scores are even harder to make accessible than printed ones, above all those containing
common Western notation. Often, the aspect of greatest interest to the viewer, whether a scholar or a
mere enthusiast, is the handwriting style. Moreover, ancillary signs typically omitted in a printed edition
(e.g., working indications and corrections) are of paramount interest. Even if the symbolic content were
correctly rendered, the original aspect would be very hard to return to BVI people. Providing a version
accessible for BVI people and capable of returning Puccini’s handwriting style is possible, both in the
analog domain (e.g., by engraving a surface) and in the digital domain (e.g., by using images with high
contrast or tactile graphics), but is not as straightforward as converting symbolic information, say, into
braille.</p>
        <p>Once again, let us refer to the materials of the Ricordi Historical Archive to exemplify the scenario,
and, specifically, to a page excerpted from Madama Butterfly by Puccini (see Fig. 2).6 In addition

to the autograph musical notation, the page contains additions and deletions that reveal Puccini’s
compositional process, along with multiple annotations added at various stages using colored pencils.</p>

      <title>4. Discussion</title>
      <sec id="sec-4-1">
        <title>4.1. The Role of Digital Technologies</title>
        <p>To overcome the problems that hinder archive openness and accessibility, digital technologies can
provide efective solutions. This approach embraces (at least) three aspects:
1. Digitization – This term identifies the process of converting physical materials into digital
formats, enabling easier access, preservation, and dissemination of information. Please note that
music archives can also contain born-digital materials, as in the case of stage photos taken by
digital cameras or score editions produced via digital score editors;
2. Cataloging and indexing – Cataloging involves both descriptive metadata, namely detailed
descriptions of each digitized item (e.g., title, author, date, etc.), and technical metadata (i.e.
information about the digitization process, such as scanner settings, file formats, and resolution).
Indexing refers to the process of creating a structured system to organize, categorize, and retrieve
digitized materials eficiently, thus making it easier for users to search and access specific content;
3. Exploitation and distribution – Ad hoc user interfaces can support searching, browsing, and
interacting with digitized content. In this context, the goal is to provide also impaired people with
a smooth and pleasant user experience. These interfaces can be designed for online or ofline
use, but, in the latter case, huge access is harder to guarantee, requiring a “here and now” model
of experience. Possible examples are multimedia installations and kiosks publicly available at
exhibitions, such as the one shown in Fig. 3.</p>
        <p>The importance of technology-enhanced approaches is now evident to many stakeholders, including
the most traditional ones [16, 17, 18]. One of the reasons not mentioned so far lies in the new perspectives
for content access, including so-called music information retrieval (MIR) [19].</p>
        <p>Unfortunately, digitized collections remain a minority among the vast array of records held by cultural
institutions. This is due not only to the high costs and technical expertise required for producing
topquality digital copies and metadata but also to the inherent limitations in digitizing all collections.
Firstly, technological obsolescence presents challenges in accessing materials stored in outdated formats.
While scanning paper materials or photographing physical objects poses no problems, consider the
case of having to acquire audio information saved on magnetic wire or wax cylinder. Similarly, finding
equipment capable of reading magnetic tapes in VHS or Betamax format is increasingly dificult.
Secondly, digitization programs often prioritize certain materials considered “high priority”, leading to
the exclusion of perishable materials deemed less significant or valuable. Thirdly, copyright issues may
prevent or discourage the release of certain collections, even when digital copies exist [20].</p>
        <p>In this regard, the Ricordi Historical Archive represents a virtuous case. Almost all of the collections
have been digitized and indexed, and many of the items have been made available in digital format on
various institutional Web platforms, including the abovementioned Internet Culturale portal.</p>
        <p>Even if most of the activities described so far fit the goals of opening archives in general, some aspects
are peculiar to music archives. The richness and heterogeneity of a music archive lie in its ability to
preserve and present a diverse array of materials that reflect the multifaceted nature of music as an art
form, cultural expression, and social phenomenon. A music archive typically preserves sheet music,
audio recordings, visual materials such as photographs, posters, and concert flyers, correspondence
and personal papers, tools and equipment, audiovisual materials, and publications. Translated into
the digital domain, a music archive holds heterogeneous media objects including texts, images, audio
tracks, video content, and music scores. Furthermore, within a music archive, many materials exhibit
relationships that extend far beyond the typical ones retrievable in a relational database. For instance,
score, audio, and video materials referring to the same music piece can be synchronized to realize
score-following applications.</p>
        <p>For the general audience, this scenario enables the design and implementation of particularly rich
user interfaces with specific forms of interactivity, such as the score follower shown in Fig. 3. But, in the
context of accessibility, the interconnection of multiple materials also fosters the design of multimodal
interfaces, where impaired senses can be compensated through sensory substitution tools.</p>
      </sec>
      <sec id="sec-4-2">
        <title>4.2. Making Archive Content Accessible to Impaired and Disadvantaged People</title>
        <p>In this section, we will address good practices to make music archives accessible, usable, and inclusive.
Digitizing materials is a crucial step in opening the shrine of music archives, but is not enough to
make them enjoyable for everyone. In this context, it is essential to consider how stakeholders manage
access to digitized objects. A widespread practice from archives, theaters, and other institutions is to
keep digitized material reserved for internal use with the aim of consultation or mere preservation.
There can be many reasons for such a policy, ranging from rights management to the protection of the
economic value of an archive, from the lack of a dedicated technological platform to the absence of a
vision focused on open access.</p>
        <p>Now we propose some approaches to broaden the audience of music archives, which should include,
to cite but a few examples, scholars with physical impairments, enthusiasts with no access to adequate
music education, foreign people who do not understand the original language of a document, and users
with cognitive impairments who understand diferently what they are reading or listening to.</p>

          <p>The first step towards openness and accessibility of archive materials is the dissemination and
distribution of their digitized versions. Stakeholders can adopt several strategies and approaches, such as
showcasing digital materials during open events and implementing publicly available ofline
applications, but an efective way is to organize digital data and metadata in a multimedia database and release
ad hoc Web platforms.</p>
          <p>The potential of the so-called semantic Web can also be efectively exploited in the field of cultural
heritage, using technologies and ontologies specific to this domain [ 21, 22, 23]. The semantic Web
fosters the interoperability and integration of information from diferent sources, enhances the ability
to perform complex searches, and allows data visualization through advanced tools (such as knowledge
graphs).</p>

          <title>4.2.2. Coexistence of Public and Private Places to Access Music Archives</title>
          <p>Accessing digitized materials on the Web requires an electronic device (e.g., a personal computer,
a tablet, a smartphone, etc.) and an Internet connection. Even if Internet connections are more
and more widespread, there are still people “ofline”, depending on age, education, technological or
economic reasons. For example, conditions of geographical isolation or social disadvantage can bring
educational poverty and prevent access to digital resources. This condition is captured by the term
“digital divide” which refers to disparities in Information and Communications Technology access, usage,
and outcomes [24]. To make a Web-based approach inclusive, we encourage the presence of easily
accessible public spaces equipped with ad hoc tools, such as Web-connected personal devices or shared
totems. These devices can be installed in the institutions that host the archives as well as in other public
spaces such as libraries, schools, and universities. An example is the digital music collection of the
Biblioteca Europea di Informazione e Cultura (BEIC), which hosts thousands of audio tracks that can be
fully accessed only by connecting one’s personal device to the institution’s internal network; otherwise,
only a 30-second preview is available.</p>
          <p>With the coexistence of private and public spaces, equal opportunities are ofered, on one side, to
people who cannot physically go to a specific site, allowing them to find what they are looking for in a
Web portal, and, on the other side, to people not owing a suitable device or Internet service to let them
enjoy materials in a space open to everyone.</p>

          <title>4.2.3. From Physical Documents to Digital Information</title>
          <p>Starting with the non-trivial assumption that the contents of the archive have been digitized, organized,
and enriched with descriptive and technical metadata, the problem becomes how to represent in an
inclusive way the information they carry. Automatic or supervised tools can come into play to extract
information from a physical object and make it accessible in the digital domain.</p>
          <p>Referring to the case of the letter in Section 3.1, it is common to consider descriptive metadata such
as date, sender, and recipient, and extract technical data from the file itself. However, it would be useful
to provide an alternative description of the content to make it accessible even to the BVI. In the case of
a letter, it is also important to transcribe its content into plain text. Transcription can be useful not
only for an aiding device, such as a screen reader or a braille display, but also to allow rewriting the
text with the aim of a large language model, so as to update it to the current language or make it more
understandable to young or cognitively impaired readers.</p>
          <p>Also for handwritten or printed scores, as shown in Section 3.2, digitization should be followed by
transcription. In fact, in the absence of the latter activity, the digital copy of a physical score would
remain largely inaccessible to people with visual impairments and incomprehensible to people who
cannot read it. Textual metadata, if present, can alternatively be shown by a screen reader or a braille
display, but symbolic information would be unavailable to disadvantaged users.</p>
          <p>Optical Music Recognition (OMR) systems, increasingly specific and accurate, provide a solution.
Unfortunately, these automatic tools are still experiencing problems with handwritten notation, but new
approaches based on computer vision and machine learning are paving the way to new possibilities [25].
Transforming a physical score into a digital one makes it possible to generate sound renditions such as
MP3 or MIDI files. Moreover, music symbols can be exported to more accessible formats, such as braille
music. Other interchange formats, e.g. MusicXML [26], can be used as a bridge to other computer-based
applications. As an example, Talking Scores [27] is a tool that entails a verbal rendition of score details
(e.g., note, duration, expression) accompanied by brief musical excerpts. Other significant uses of
MusicXML as a bridge to other applications are provided by MakeBraille,7 BrailleMuse,8 and software
from Sao Mai Braille and Dancing Dots that facilitate the conversion of MusicXML into braille.</p>
          <p>Desktop and mobile applications such as Power Music 9 and forScore 10 should also be reported. They
7https://makebraille.dzblesen.de/MakeBraille
8https://www.braillemuse.net/
9https://powermusicsoftware.com/
10https://forscore.co/
are digital score readers, scanners, managers, and organizers, and enable users to enlarge digital sheet
music, import PDF files, and perform playback operations such as adding a metronome to the digital
score.</p>
          <p>Unfortunately, the issue of providing an accessible counterpart of the original image remains unsolved
for BVI people. The richness and cultural interest of handwritten notation and autograph writing can
be returned only in alternative ways. A typical form of sensory substitution in use for artwork, i.e.
haptic reproduction, can be implemented only in a physical space.</p>
          <p>This problem is even more critical when the original materials are three-dimensional objects and
two-dimensional representations cannot catch their content completely, as in the case of costumes and
wigs. In this field, 3D printers still represent an impractical solution, as they are not widely available at
a personal level, require ad hoc models of the objects to be rendered, are limited concerning printable
materials, and are too slow for on-the-fly fabrication.</p>

          <title>4.2.4. The Pivotal Role of User Interfaces</title>
          <p>Central to the theme of accessibility is the role of user interfaces (UIs), not only for enhancing user
experience but also for ensuring that music content is accessible to all individuals, regardless of their
abilities or technological proficiency.</p>
          <p>A well-designed UI can significantly enhance the user experience by making it intuitive, eficient, and
enjoyable to navigate archive content. A seamless UI ensures that users can focus on the content itself
rather than struggling with navigation or functionality issues, thereby fostering a deeper engagement
with the music-related content.</p>
          <p>Web UIs serve as the bridge between users and the repositories of music available online. One of the
most crucial aspects of Web UIs is their role in making music content accessible to everyone, including
individuals with disabilities. Web accessibility involves designing interfaces that can be used by people
with a wide range of abilities and disabilities. For example, visually impaired users usually rely on
screen readers to navigate Web pages. Ensuring that an interface is compatible with screen readers
means providing descriptive alternative text for images, using semantic HTML for better structure,
and supporting keyboard navigation. People with hearing impairments can benefit from features such
as subtitles for music videos, lyrics display, and visual cues for audio content. Web designers and
developers can refer to the WAI guidelines to create accessible content that ensures accessibility.</p>
          <p>The implementation of accessible UIs requires a concerted efort from designers, developers, and
content creators. It involves the integration of various technologies and best practices to ensure that
the UI is user-friendly and compliant with accessibility standards. This includes responsive design to
cater to diferent devices, intuitive layout and navigation, and robust testing with assistive technologies.
Continuous feedback from users with disabilities is also vital in refining and improving the accessibility
of the platform.</p>
          <p>Accessible UIs contribute to the cultural enrichment of society by democratizing access to diverse
musical genres and artists. This cultural inclusivity promotes a richer and more diverse musical
landscape.</p>

          <title>4.2.5. Designing and Implementing Multimodal Representations</title>
          <p>Since music archives typically contain heterogeneous information and music-related content lends itself
to forms of integrated visualization (for example, a score follower synchronizes score images and audio
tracks), a special category of applications concerns multimodal access [28, 29]. Multimodality refers to
the use of multiple sensory modalities to convey information, engage users, and facilitate interactions.
In the context of overcoming impairments, multimodality is a powerful approach that can significantly
enhance accessibility and inclusivity. By leveraging diferent modes of communication, such as visual,
auditory, and tactile inputs, platforms and interfaces can be made more usable for people with various
disabilities.</p>
          <p>By providing multiple ways to access information, multimodal interfaces ensure that users can choose
the mode that best suits their needs. This form of redundancy is crucial for overcoming the limitations
posed by specific impairments. By catering to diferent sensory preferences and needs, these interfaces
can make interactions more enjoyable and efective.</p>
          <p>Finally, the incorporation of multimodal elements can ensure that interfaces remain accessible and
adaptable to new developments. This adaptability is essential in creating sustainable and long-lasting
accessibility solutions.</p>
          <p>A notable example of a structured approach to multimodal representation in music archives is
the IEEE 1599 format [30]. Designed as a multilayer framework for encoding music information,
IEEE 1599 integrates diferent modalities within a single structured document, including symbolic
notation, audio recordings, visual representations, and analytical metadata. This format enables precise
synchronization between heterogeneous content, facilitating advanced applications such as
scorefollowing systems, interactive music analysis, and educational tools. Moreover, its layered architecture
allows for personalized accessibility features, such as dynamic adaptation for visually impaired users
through braille notation or for hearing-impaired users through haptic feedback. By adopting IEEE 1599,
music archives can enhance openness and accessibility, ensuring that users with diverse needs can
engage with musical content in a flexible and inclusive manner. Other multilayer formats for music
description, such as MEI and MusicXML, have been described in [31].</p>

      <title>5. Conclusions</title>
      <p>The goal of this work was to investigate the aspects of openness and accessibility in music archives.
Unlocking music archives has a significant importance in various domains, including cultural
preservation, academic research, education, and personal enjoyment. Ensuring that these archives can be
accessed ofers numerous benefits, encouraging a deeper understanding and appreciation of music and
its role in society.</p>
      <p>In this context, user interfaces play a key role. They can enhance user experience, ensure accessibility,
and contribute to cultural diversity. As technology continues to evolve, it is imperative that new
platforms prioritize the development of accessible UIs capable of transcending barriers in music archive
exploration.</p>
      <p>There is growing awareness towards the issue of openness and accessibility. Openness has long been
at the center of scientific and cultural debate. Sufice it to mention open access in scientific publications
or open data released by governments and public institutions. But accessibility is also becoming more
and more prominent in the debate. Formats such as braille music, aiding devices such as screen readers,
and technologies such as the Web Speech API can help make music archives more accessible.</p>
      <p>To achieve these goals, the managers of music archives, stakeholders, and policymakers must do
their part, opening archives to the outside world in an accessible and inclusive manner, implementing
best practices, and ensuring an enjoyable experience for impaired or disadvantaged users.</p>
