This paper introduces the RASH Framework, i.e., a set of specifications and tools for writing academic articles in RASH, a simpli- fied version of HTML. RASH focuses strictly on writing the content of the paper leaving all the issues about its validation, visualisation, conver- sion, and data extraction to the tools developed within the framework.

Besides the obvious justifica- tion of simplification and unification of data formats for drafting, submission and publication, an additional underlying rationale is that the adoption of HTML in the context of scientific publications would ease the embedding of semantic annotations, thus making a step towards the improvement of research communi- cations thanks to already existing W3C standards such as RDFa and Turtle. The adoption of Web-first formats in scientific literature, i.e., HTML and RDF, is a necessary step towards the complex (and exciting) scenarios that the Semantic 2 Angelo Di Iorio et al. Publishing has promised us [1] [6]. However, such formats should support the needs of the actors involved in the production/delivery/use of scholarly articles. Along the lines of other existing works on this topic (e.g., Linked Research project [2] and ScholarlyMarkdown [5]), in this paper we introduce the RASH Framework, i.e., a set of specifications and tools for writing academic articles in RASH (an HTML+RDF-based markup language for writing scholarly docu- ments) which aims at addressing all the aforementioned issues. The rest of the paper is structured as follows. In Section 2 we introduce the rationale for the RASH Framework. In Section 3 we provide a quick overview of all its tools, that are available in the Framework repository. Finally, in Section 4 we conclude the paper sketching out some future developments. 2 A “Web-first” framework for research articles Some works, e.g., Capadisli et al. [2], suggest not to force any particular HTML structure for research papers. In this way, the author of a paper is free to use any possible kinds of HTML linearisations for writing a scholarly text. This freedom could, however, results in two main kinds of issues: – visualisation bottleneck – it may affect the correct use of existing, well- developed and pretty standard CSSs; – less focus on the research content – the fact that a certain paper is not visualised in a browser very well could bring the author to work on the presentation of the text, rather than on its research content. A further complication to an already complex scenario comes from the nec- essary involvement of publishers. Leaving the authors free of using their own HTML format could be also counterproductive from a publisher’s perspective, in particular when we speaking about the possibility of adopting such HTML formats for regular conference/journal camera-ready submissions. The RASH Framework7 has been proposed in order to address all the afore- mentioned issues. It is a set of specifications and tools for writing academic articles in RASH - a summary of the whole framework is introduced in Fig. 1. The Research Articles in Simplified HTML (RASH) format is a markup lan- guage that restricts the use of HTML elements to only 25 elements for writ- ing academic research articles, and it is entirely based on a strong theory on structural patterns for XML documents [4]. It allows authors to use RDFa an- notations within any element of the language. In addition, RASH allows the use of elements script (with the attribute type set to “text/turtle” or to “appli- cation/ld+json”) within the element head for adding plain Turtle or JSON-LD content. Any RASH documents begins as a simple (X)HTML5 document8 , by 7 The full project is available at https://github.com/essepuntato/rash/.

Validation. All the markup items in RASH are defined as a RelaxNG gram- mar and are compatible with HTML5. We have developed a script to enable RASH users to check their documents simultaneously both against the specific requirements in the RelaxNG grammar and also against the full set of HTML checks that the W3C Nu HTML Checker does for all HTML documents. Visualisation. The visualisation of RASH documents is rendered by the browser in the current form by means of appropriate CSS3 stylesheets and javascript scripts developed for this purpose. We are actually using some ex- ternal libraries, i.e., Bootstrap and JQuery, in order to guarantee the current clear visualisation and for adding additional tools to the user. As an example, the RASH version of this paper is available at https://rawgit.com/essepuntato/ rash/master/papers/rash-demo-iswc2015.html. Conversion. We have spent some efforts in preparing XSLT 2.0 documents for converting RASH documents into different LaTeX styles, such as ACM ICPS and Springer LNCS. This is, actually, one of the crucial steps to guarantee the use of RASH within international events9 and to be able to publish RASH doc- uments in the official LaTeX format as required by the organisation committee 9 https://github.com/essepuntato/rash/#venues-that-have-adopted-rash-as- submission-format 4 Angelo Di Iorio et al. of such events. In addition, we have already developed another XSLT 2.0 docu- ment to perform conversions from OpenOffice documents into RASH documents, which allows authors to write a paper through the OpenOffice editor and then converting the related ODT file into RASH automatically. Enhancement. A recent development of the RASH Framework has con- cerned the automatic enrichment of RASH documents with RDFa annotations defining the actual structure of such documents in terms of the Document Com- ponent Ontology (DoCO) [3]. In particular, a Java application called SPAR Xtractor suite has been developed: it takes a RASH document as input and re- turns a new RASH document where all its markup elements have been annotated with their actual (structural) semantics. 4 Conclusions In this paper we have introduced the RASH Framework, i.e., a set of speci- fications and tools for writing academic articles in RASH. We have discussed the rationale behind the development of RASH, and we have presented the lan- guage with all the validation/visualisation/conversion/extraction tools we have developed so far. As immediate future developments, we plan to create addi- tional scripts for extracting RDF statements from RASH documents according to SPAR Ontologies (http://www.sparontologies.net), and to develop addi- tional XSLT documents in order to convert DOCX documents into RASH and to convert RASH documents into several formats for scholarly communications, such as EPUB, DocBook, and LaTeX IEEE styles.
