        <p>Managing ESG (environment-social-governance) policies becomes a critical need in small and medium enterprises, as pressure and requirements come from many stakeholders - legislation, banking, supply chain partners etc. The regional business environment where our research originates is absorbing this pressure by organizing frequent workshops with local business and IT clusters to find reusable solutions, to come up with ESG capabilities or to promote (software) products that may help with some aspect of ESG accounting. The data-centric and analytics approaches are prevalent in such workshops, offering quantitative reporting templates from data assumed to be available in legacy databases and spreadsheets sometimes augmented with IoT solutions. However, ESG is not all about quantitative aggregations of data - as a complement to such efforts, an emerging requirement also calls for “how-to” guidance, mappings of granular data sources and their traceability to enterprise aspects - in short a knowledge management capability that can deal with where exactly ESG concerns manifest and propagate through enterprise layers. To meet this requirement, we advocate conceptual model-based analysis that puts emphasis on relationships, i.e. dependencies and traceability, rather than spreadsheets and data points. Our paper reports on initial Design Science steps to address the lack of ESG knowledge management capabilities by converging recent work on enterprise modeling and knowledge graphs, specifically by leveraging tools that integrate a knowledge graph treatment with BPMN and metamodel extensions that capture relationships relevant to ESG.</p>

      <title>1. Introduction</title>
      <p>ESG accounting aims to mitigate concerns regarding environmental impact, social responsibility, and
corporate governance. It also raises requirements that small and medium enterprises (SMEs) must
satisfy within rather urgent timeframes – such requirements are imposed by legislation, through
financing institutions or business pressure along supply chains. SMEs must respond and design ways
to self-evaluate governance performance and sustainability in relation to the environment, but
support for this comes primarily as data-driven reporting tools rather than prescriptive methods.</p>
      <p>During a series of workshops held in our regional business environment, we arrived at the
motivating conclusion that ESG is not strictly a use case for data analytics, it is a systemic concern
that must also be tackled by means of Information Systems analysis. The workshops involved,
besides SMEs interested in building their ESG accounting capabilities, several other types of
stakeholders: (a) software providers promoting ESG tools, (b) legal stakeholders and regulators
warning that ESG is a matter of systems-of-systems, and (c) funding bodies exemplifying systemic
constraints that emerge from ESG, including mechanisms of propagating those constraints.</p>
      <p>This calls for organizations to ensure semantic traceability of ESG concerns, to become aware of
how those concerns relate to various aspects of an enterprise and its existing processes. Traditional
enterprise systems analysis and design successfully employed conceptual modeling methods, and
enterprise knowledge graphs are a state-of-the-art approach for data integration and traceability.
The hereby reported work aims to leverage both in order to build a novel ESG knowledge
management capability where ESG concerns, with their associated knowledge objects, data objects
and responsibilities, are mapped on enterprise models and exposed to a “Knowledge Graph
treatment” for semantic navigation/traceability and rule-based reasoning.</p>
      <p>For this paper, we currently focus on business process management capabilities as a foundation
on which ESG knowledge management capabilities can be built, however we envision that this idea
can extend to many aspects of enterprise architecture management (EAM) – we employ the umbrella
term of „enterprise modeling” to reflect such generalization potential.</p>
      <p>
        ESG policies and risks do not have only an ideological role, promoting sustainability and social
responsibility, they are already impacting investment decisions [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ]. There is a need for more
effectively managing the ESG-associated risks and governance issues and this demands a pro-active
look at how ESG is integrated inside the enterprise architecture, not only a reactive stance to external
demands and impositions. Even when associated with non-financial reporting, ESG policies can lead
to enhanced profitability [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ]. The European Union specifically prioritized ESG during recent years.
B Corp certification [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ] is awarded by B Lab to companies meeting certain ESG criteria: governance,
employees, environment, community, and customer relations. High ESG ratings and improved
performance, especially in the social dimension, can improve firm value by reducing risks, therefore
thousands of companies over the recent few years achieved the certification [
        <xref ref-type="bibr" rid="ref4">4</xref>
        ].
      </p>
      <p>
        Moving to the conceptual modeling context, in Business Process Management (BPM)
organizations typically map on granular process tasks, estimates of times, costs and various
dependencies commonly used for simulations or process analytics reports. The initial idea of our
work was to re purpose such annotation mechanisms to reflect ESG concerns. On tooling level,
metamodeling becomes a critical capability to extend legacy BPMN tools towards so-called DSMLs
(domain-specific modeling languages) that hybridize BPMN with ESG conceptualizations.
Sustainability concerns already have led to the emergence Green BPM [
        <xref ref-type="bibr" rid="ref5">5</xref>
        ], placing particular
emphasis on the environmental impact of business processes; GRC (governance, risk, compliance) is
gradually incorporated in tools of traditional BPM suites and vendors [
        <xref ref-type="bibr" rid="ref6">6</xref>
        ], however not leveraging
yet the emergence of enterprise knowledge graphs, thus missing an opportunity (highlighted by this
work) of conceptual convergence between the business view on ESG and the technological view on
enterprise data. Such a convergence was hinted at in recent works for other application domains –
e.g. for supply chain management [
        <xref ref-type="bibr" rid="ref7">7</xref>
        ] or for work systems [8]. The convergence is made possible by
a systemic perspective and the semantic traceability requirements raised by such a perspective and
can be transferred to new methods of ESG-aware BPM or EAM as envisioned in this paper.
      </p>
      <p>Current ESG methods and tools, to be surveyed in Section 2, care mostly about quantitative
computation – i.e. data aggregation/analytics for various score sheets structured according to ESG
pillars. However, if “knowledge is in relationships” knowledge management capabilities must start
from devising means of capturing and maintaining the intricate semantic networks that connect ESG
concerns to business operations or enterprise architectures. For our work the starting point is BPM
as a practice and BPMN as tool support extended towards ESG relevance. By integrating BPMN
modeling into ESG methodologies, followed by the conversion of diagrammatic visualizations into
knowledge graphs, we enable process-centric analysis through an ESG lens. Knowledge graphs
enable the navigation of dependencies and the use of traceability as constraints for data aggregations
and retrieval, thus supporting more informed decisions to drive ESG strategies.</p>
      <p>The remainder of the paper is structured as follows: Section 2 establishes the landscape of current
methods for reporting ESG factors. Section 3 introduces the problem and the originating motivation.
The research methodology that hybridizes Design Science with a metamodeling framework is
presented in Section 4. Section 5 formulates and exemplifies the proposal of repurposing and
expanding the scope of Business Process Management towards a process-centric ESG
knowledgedriven approach. The paper concludes with an outlook to future work.</p>

      <title>2. Background on ESG tooling</title>
      <p>The Environmental aspect of ESG assesses the company’s impact on the natural ecosystem, such as
reducing carbon emissions, efficiently using resources in production processes, pollution, waste
management, or efforts to produce eco-friendly products or provide sustainable services. The Social
factors refer to the company’s relationships with customers, workforce, local community, and other
stakeholders. Corporate Governance focuses on upholding transparency, accountability, and ethical
practices in company management. There are several tools helping companies to incorporate
sustainable goals into companies’ activities. A problem identified by a team of researchers at MIT
Sloan is that ESG assessment diverges substantially among the tools that evaluate the ESG impact
[9]. We have looked at several such tools and associated methodologies.</p>
      <sec id="sec-2-1">
        <title>2.1. Morningstar</title>
        <p>Morningstar Sustainalytics [10] utilizes three building blocks in calculating the ESG Rating:
corporate governance, material ESG issues and idiosyncratic issues. The main building block of the
ESG Risk Ratings is represented by Sustainalytics’ set of material ESG issues, supported by 300 ESG
indicators. It combines more than 300 criteria such as ESG risk, Management, Exposure, etc., drawing
upon 10 international standards and norms like the Global Reporting Initiative [11], Sustainability
Accounting Standards Board, or World Economic Forum [12]. Moreover, they categorize the
companies according to 3 levels: Global 50 Top Rated, Industry Top Rated and Regional Top Rated.
If a company is included in one of the categories mentioned before, the badge can be used in
company’s reports, on their websites, email signatures, social media channels etc. 2024 ESG
TopRated Badges report shows the list of the companies and their qualificative [13], this top including
14000 companies operating globally across 14 industries.</p>

        <title>2.2. Bloomberg</title>
        <p>Bloomberg [14] offers a range of proprietary scores that enable investors to evaluate company or
government disclosure and performance across diverse ESG aspects (e.g. sustainable products,
climate exposure, ethics &amp; compliance, board composition etc.). Bloomberg has defined several
indexes to evaluate companies’ sustainability, for example Bloomberg Gender-Equality Index (GEI).
The report of Bloomberg Gender-Equality Index of 2023 includes 484 companies from 54 industries
[15].</p>

        <title>2.3. MSCI (Morgen Stanley Capital International)</title>
        <p>MSCI ESG rating calculates a company’s management or financially relevant ESG risks and
opportunities [16]. It uses the 3 pillars of ESG divided into 10 themes and 33 ESG key issues [17] .
Based on the final score, it provides 3 categories of results: leader, average and laggard.</p>

        <title>2.4. Asset4 Framework</title>
        <p>Asset4 Framework [18] was developed by Refinitiv, a London Stock Exchange Group (LSEG), a
former division of Thomson Reuters. In 2019, LSEG acquired Refinitiv. Their tool’s evaluation
(Refinitiv) focuses on specific subcategories, including Emissions, Resource Usage, Innovation,
Human Rights, Portfolio Product Responsibility, Human Resources, Community Management,
Shareholders, and CSR Strategy. Unlike Morningstar Sustainalytics, Refinitiv collects companies’
public data from their sustainability reports. LSEG measures 2 ESG relates scores: a) ESG score
(assesses the company’s ESG performance using publicly available and verifiable reported data) and
b) ESGC score (integrates the ESG score with ESG controversies to offer a deep assessment of the
company’s sustainability impact and behavior across time) [18]. The assessment comprises more
than 630 ESG measures. Each indicator has a specific weight used in the final calculation, depending
on the industry (e.g. the methodology from December 2023 provides the following data: for Hotels
&amp; Entertainment Services, the innovation measure weights 2%, while Healthcare Equipment &amp;
Supplies has 6% - these percentages are based on a sample ESG data, and they can vary). At the end,
each company is classified in a category from A to D (ESG Leaders to ESG Laggards – like MSCI
classification [17]).
2.5. GRESB
GRESB (Global Real Estate Sustainability Benchmark) [19] is an independent organization that offers
verified ESG performance data and comparative benchmarks to investors and managers, focusing on
real estate and infrastructure sectors. The GRESB Estimation Model (GEM) provides accurate
estimates of missing data regarding energy consumption and greenhouse gas (GHG) emissions for
members participating in the Real Estate Assessment offered by GRESB [20]. This model is based on
a global database containing approximately 170,000 individual assets from various real estate
markets.</p>

        <p>OpenESEA [21] is a modeling approach that can be used by organizations to assess their ethical,
social, and environmental aspects. The primary benefit of the tool lies in its integration of diverse
methods, including the B Impact Assessment, Common Good Balance Sheet, GRI Standards [11],
Sustainable Development Goals Compass [22], UN Global Compact [23], and others. Organizations
have the flexibility to incorporate the approaches of their choice. A series of direct and indirect
indicators are extracted from the methods analyzed - e.g. total water used and lowest wage belonging
to B Impact Assessment.</p>

        <title>2.7. Research objective relative to the existing ESG tools</title>
        <p>The existing ESG impact tools focus on aggregating indicators like reducing carbon emissions,
optimal use of resources in the product process, optimal working conditions, workplace equality of
opportunities etc. The research reported in this paper aims to complement current quantitative
practices with an approach that enables the conceptualization of ESG policies and risks in terms of
traceability of influences on various elements of enterprise architecture, including business
processes, decision-making factors, properties/components of products and services. The widely
adopted standards such as BPMN, DMN, ArchiMate, etc., do not inherently support through first
class constructs the ESG perspective and this work aims to bridge the gap by leveraging our
experience with metamodeling frameworks and their interplay with knowledge graphs.</p>

      <title>3. Problem identification and motivating requirements</title>
      <p>The originating circumstance of this work was a series of workshops organized by local industry
clusters in our region (Cluj area, Romania) – typically IT-focused clusters promoting software
products for ESG concerns, funding and regulatory bodies explaining business restrictions arising
from ESG alignment and SMEs interested in this alignment and how their general management
practices must change. While ESG requirements are still confusing for some companies, SMEs hope
to „tick boxes” by acquiring some software products but most of them are aware this is insufficient ,
recognizing that ESG is a larger systemic paradigm that requires internal capabilities baked into the
enterprise architecture (EA). Regardless of the advertised tooling, all workshops have lead to
discussions on knowledge management concerns, on „how to manage” rather than how to write a
report imposed by the regulations.</p>
      <p>We’ve looked into knowledge management capability frameworks to try to compare their
coverage with the awareness we observed during those workshops. APQC established a tool for
assessing knowledge management capabilities [24], which proposes a taxonomy of capabilities
consisting of 4 classes depending on the knowledge management practices and knowledge objects
being explicitly managed:
•
•
•
•</p>
      <p>Strategy: pertaining to objectives, business case and budgeting;
People: pertaining to resources, governance, change management and communications;
Process: pertaining to knowledge flows, knowledge management methods and associated
measurements;</p>
      <p>Content &amp; IT: pertaining to content management and information technology.</p>
      <p>The ESG solutions discussed in the SME workshops were missing most of these – in most cases we
were able to only identify instances of: objectives concerns - what ESG aspects should be reported, for
what purpose; IT concerns - from what IT systems some ESG-relevant data can be obtained;
communications concerns - who needs to communicate which report to a certain ESG stakeholder
(mostly to external ones such as authorities, lacking any preoccupation with internal knowledge
flows and traceability). In isolated cases there have been also mentions of: budgeting (how a dedicated
budget should be managed for ESG ); content management (e.g. having a free structure wiki on how
to build certain ESG reports); governance (e.g. having a recurring standard operating procedure for
building reports and communicating them in due time).</p>
      <p>Even for the recognized aspects, the general state of practice showed a general lack (a) of
relational connectivity (and therefore of traceability) of ESG concerns and (b) of agile granularity, to
be able to shift the level of aggregation for data by mapping it to diverse enterprise architecture
elements. This manifests in a general inability to answer diverse competency questions regarding
ESG – all data retrieval being inspired by the traditional accounting practices, with fixed procedures
designed to feed a fixed report template, although ESG continuously evolves in both granularity and
ontological models.</p>
      <p>(a) The first point (lack of connectivity) requires a certain level of semantic interoperability
ensuring shared understanding within the organization of the involved concepts and how they map
to the business objects and business operations. The workshops showcased a variety of off-the-shelf
IT products offered for any application domain and imposing their own conceptualization, assuming
manual input of data of unknown provenance and improvised granularity. The most advanced tools
also involved IoT data retrieval (e.g. solar panels to improve sustainability of certain processes), but
all tools were clearly designed starting from a rigid data model expecting direct data input, rather
than an evolving ESG data fabric;</p>
      <p>(b) The second point (lack of agility in granularity) refers to a need to ensure that ESG-relevant
content can be mapped anddrilled-down to EA elements - e.g. process tasks/events drilled down into
subprocesses (in BPMN sense), application components, technology components, locations (in
Archimate sense) drilled down to subcomponents/sublocations etc. This can extend the existing
reporting practices on the same level of granularity as the already in-place BPM/EAM culture. On
the other hand, at least for SMEs involved in the mentioned workshops, such a legacy culture was
mostly absent; EAM was never mentioned, while BPM made its way to some extent in the context
of the recent popularity surge of Robotic Process Automation, leading to the creation of various
„process maps” as basis for RPA projects documentation.</p>
      <p>These insights from the regional business context inspired the initiation of a Design Science
project that leverages our experience as an OMILAB Node2 with enterprise modeling, particularly
with business process modeling and knowledge graphs, to come up with traceability mechanisms
based on BPMN that compensate the two gap points indicated above. This can lead to a (BPMN
2 https://econ.ubbcluj.ro/omilab/
centric for now, to be extended to a full -fledged DSML) knowledge management capability for ESG
accounting that leverages three key ingredients:
•
•
•
procedural knowledge assumed to exist in a company;
metamodeling to extend the process description vocabulary in order to incorporate
ESGrelevant data attributes;
knowledge graphs to maintain the contextual linking of all these information and to enable
on-demand data retrieval - according to semantics of the BPMN-ESG hybridization and the
granularity of drilled-down procedural knowledge (different levels of subprocesses, filtered
by various criteria).</p>

      <title>4. The DSR-AMME treatment development framework</title>
      <p>The key challenges of absorbing ESG are not limited to ensuring a new business interface (i.e.
transparency and reporting of ESG-relevant data). They also entail modifications in business
processes (e.g. new tasks, new documents, new communication), entirely new processes (e.g. waste
handling, circular processes), new properties attached to enterprise architecture elements (e.g.
gender quotas per department), entirely new architecture components (e.g. ESG-oriented software
products hooked in the IT architecture, solar panels as technological components). As we’re now
focusing only on BPMN, not all these are currently addressed in our work, but it is obvious that
employing enterprise modeling for knowledge externalization – a new interpretation on Nonaka’s
knowledge conversion spiral [25] – requires such aspects to become first-class modeling constructs
in the modeling grammar; therefore, a metamodeling framework is also required to build this
capability.</p>
      <p>Such a capability qualifies as a Design Science Research (DSR) treatment that needs to evolve
iteratively as the scope, domain-specificity and granularity requirements for ESG evolve rather fast.
Consequently, our work needs to follow a hybrid framework where the DSR iterative process, i.e.
Peffer’s process [26], incorporates in the Design &amp; Development phase a “method engineering”
framework that also entails the iterative deployment of DSMLs to make the proposed treatment
operational.</p>
      <p>As it is customary in the OMILAB community of practice when working on language
customizations, we opt to apply AMME (Agile Modeling Method Engineering) [27]and to customize
the existing BPMN implementation offered in the open tool BEE-UP [28], a typical approach
employed in the past for domain-specific BPMN extensions [29]. BEE-UP is built on the ADOxx
metamodeling platform and benefits from an ability to generate RDF graphs from the graph structure
underlying any diagram - according to patterns introduced in [30] and recently made available as a
built-in BEE-UP option. This enables a particular flavor of mode-ldriven engineering that we labelled
in the past as model-aware engineering [31] – i.e. the repository of models becoming a knowledge
base to be probed by semantic queries and reasoning mechanisms, instead of being a graphical base
of code patterns to be subjected to transformations based on a fixed schema.</p>
      <p>Figure 1 suggests this hybridization of DSR and AMME leading to a reusable treatment
development process for research work where the design proposition is captured in a DSML and
made operational in a graphical modeling tool, with ADOxx suggested here as a low-code platform
to achieve that operationalization. The resulting knowledge graphs will naturally preserve all
customizations brought to the language, as metamodel constructs and annotation attributes are
turned by the metamodel-aware converter into RDF classes and data properties, respectively.
For the first DSR phase, we analyzed existing tools that are used for evaluating the ESG impact of
organizations, as shown in Section 2. In recent years, efforts have been made globally (such as GRI
Standards, B Corp certification, World Economic Forum, etc.) as well as at the European level (the
Paris Agreement, Directive 2014/95/EU, EU Directive 2464, etc.) to standardize ESG policies by
requiring the preparation of non-financial reports on companies’ sustainability. EU member states
transpose the European directive to their own legislation which means there can be significant
variations due to national priorities and different foci on what is the relevant granularity level. Even
if standards are available, legislation does not clearly impose a particular standard and different
scores may be obtained depending on the domain-specific properties considered relevant in different
sectors and even instance organizations. Agility at metamodel level and streamlined externalization
based on agile metamodel customizations thus become a key requirement, in contrast to the traditional
perception that diagrammatic modeling should comply to a fixed grammar – that criteria is relevant
for the model-driven engineering use cases relying on model transformations, but it becomes
irrelevant in the model-aware paradigm where arbitrary semantic enrichment must be captured as
needed and as available (and immediately exposed to semantic navigation) [31].</p>
      <p>The second stage of DSR asks for the definition of the objectives. The main objective is
represented by the development of a model-based knowledge management capability for ESG
accounting, operationalized in a visual modeling tool. Therefore, we looked at instances of ESG
policies to identify properties and relations that can be “docked” to BPMN constructs.</p>
      <p>The Design and Development stage, as shown in Fig. 1, was delegated to the AMME framework
which has its own process for identifying modeling competence requirements and developing the
tool to satisfy those requirements.</p>
      <p>Returning to the main DSR cycle, Demonstration involves testing the feasibility of the treatment
for selected cases that we identified in consulted SMEs, to be showcased in Section 5.</p>
      <p>The Evaluation of the modeling method is for now limited to competence evaluation relative to
requirements. Most evaluation criteria for tools developed on the ADOxx metamodeling platform
inherit technical qualities (and limitations) from ADOxx – look and feel, performance,
interoperability. We plan however to return to more comprehensive evaluations in terms of model
comprehension and other criteria of the SEQUAL quality framework [32].</p>
    </sec>
    <sec id="sec-5">
      <title>5. Proposal of BPMN-ESG-Knowledge Graph hybridization</title>
      <p>The tools surveyed in Section 2, as well as tools advertised during the SME workshops that motivated
this work, are fundamentally data-driven, assuming data availability (or suggesting potential
provenance) and applying various taxonomies for report structuring. By applying the lens of
knowledge management, we identify emerging requirements for traceability, agile granularity and
mappings to enterprise architecture elements, even in cases when an enterprise architecture
management practice is absent. EAM (re)surfaces as a frame for ESG concerns; even when EAM is
not explicitly mentioned, elements of EA are mentioned as categories and traceability criteria for
ESG attributes. Out of the EA layers we currently focus on business process descriptions based on
BPMN with some extensions to support certain semantic query and reasoning competencies over
knowledge graphs obtained from those process descriptions, with the help of the diagram-to-RDF
converters available in both BEE-UP (our BPMN tool of choice) [28] and the ADOxx metamodeling
platform (for extending the modeling competence / metamodels of BEE-UP) [30]. Therefore, we
currently advocate for an ESG knowledge management capability to be grafted over a pre-existing
Business Process Management practice. BPM is also interested in quantitative indicators and their
simulation, but compared to state-of-the-art ESG tools has a fundamental interest in the conceptual
workflow structure and process decompositions. This ensures a granular semantic network to which
knowledge objects and knowing subjects can be connected on a diagrammatic level and exposed to
the knowledge graph treatment.</p>
      <p>We hereby showcase two techniques for this treatment, exemplified by SPARQL queries that
illustrate case-based competency evaluations: (a) Attribute-centric – this is the simpler approach
derived from the traditional data-focused approach where ESG attributes (e.g. carbon footprint,
employee genders) are annotated to model elements, additional to the traditional BPMN attributes
typically used in simulations, and then collected by recursive queries over tasks or processes of
desired granularity; (b) Relationship-centric – this implies the linking, via ADOxx hyperlinks, of
BPMN elements to knowledge objects and knowing subjects or responsibilities from complementary
custom diagrams that maintain an inventory of knowledge objects and an organizational chart
making explicit ESG roles and even instance employees.</p>
      <p>For the first approach we showcase an example in Figure 2 describing a hiring process with one
level of embedded subprocesses and granular linking to performing employees. The recruitment
process consists of several subprocesses like the Preparing process, Sourcing process, Screening process
etc. Some of the subprocesses are also decomposed (Preparing process, Sourcing process and
Onboarding process). The process participants can be modeled by default in BEE -UP by using the
Working Environment Model – as instance employees, as roles, as departments and visual
connections between them. Any of the work environment elements can be linked to BPMN tasks –
something initially used for simulation purposes and later added to BEE-UP to maintain RACI links
(Responsible-Accountable-Consulted-Informed). In this example the Marketing Department needs a
new employee (e.g. a Marketing Officer). Besides the Marketing Department, HR Department and IT
Department are also involved in the recruitment process (for example the manager of the Marketing
Department must send the welcome pack to the new hired employee and the IT Department must
prepare the technical details – on the Onboarding subprocess).
Attribute centricity means that ESG-relevant attributes are collected and annotated for various model
elements: employees can get annotated with attributes such as gender, ethnicity; BPMN tasks get
annotated with values for carbon footprint, energy consumption, waste generation.</p>
      <p>Documenting such data around processes will help with, for instance, calculating the carbon
footprint or energy consumption for each subprocess/process; measuring the waste generation (e.g.
paperwork consuming physical paper); showing the gender quotas involved in each
process/subprocess/task type.</p>
      <p>The query examples below calculate for each department and for all manual tasks in each process
(as named graphs):</p>
      <p>SELECT ?dept (COUNT(?emp) AS ?femaleCount)
{
?emp a :Performer; :belongsTo ?dept; :gender “female”.
?dept a :OrganizationUnit.
}
GROUP BY ?dept
SELECT ?process (COUNT(?emp) AS ?femaleCount)
{
GRAPH ?process {?t a :BPMNTask; :taskType “Manual”; :responsible ?emp}
?emp a :Performer; :gender “female”
}
GROUP BY ?process</p>
      <p>For the Relationship-centric approach, we remain in the hiring scenario with the example in Figure
3 where a new subtype of BPMN data object is introduced - visually marked with “esg” and
distinguishable at metamodeling level to facilitate semantic queries. The figure shows (a) on the left
side, fragments of the recruitment process producing or consuming such ESG data objects; (b) on the
right side, an inventory of knowledge objects that produce the ESG data objects involved in certain
BPMN tasks (e.g. requirements or onboarding packages for the open positions), or are informed by
such objects (e.g. an ESG report that needs to be built by collecting data from certain tasks); (c) on
top, again the work environment (organization chart) whose elements can include ESG specific roles
and can be linked to knowledge objects.</p>
      <p>There two pathways visible to achieve RDF linking: linking constrained by the metamodel (visual
hyperlinks available to all diagrammatic elements of a certain type, for example links from
knowledge objects to roles in the organization chart) and linking unconstrained by the metamodel
(live URI and RDF triples that may adopt any description vocabulary, for instance Schema.org). A
fragment from the knowledge graph thus derived, based on transformation patterns discussed in
[30], is shown in Fig. 4 with some examples of semantic queries enabled by the resulting structure
listed in the following:
Rule example: Generate a direct dependency relationship between two knowledge objects that are
involved in the same BPMN task, one informed by ESG data objects generated by the task and the
other exposing data objects needed in the task:</p>
      <p>CONSTRUCT {?x :dependsOn ?y} WHERE
{
?x a :ESGKnowledgeObject; :informedByDataObject ?dx.
?y a :ESGKnowledgeObject; :exposedDataObject ?dy.
?dy a :ESGDataObject; :hasDataAssociation/:hasDataAssociation ?dx.
?dx a :ESGDataObject.</p>
      <p>}
Traceability example: Select all ESG data objects produced during a specific process, as well as the
ESG knowledge objects that will be informed by those:</p>
      <p>SELECT ?x ?y WHERE
{
GRAPH :SourcingProcess {?t a :BPMNTask; :hasDataAssociation ?x.</p>
      <p>?x a :ESGDataObject; ^:informedByDataObject ?y}
}
Aggregation example: Collect all processes whose tasks have a data input from objects derived from
all knowledge objects subordinated to the Employer Branding Package.</p>

      <title>6. Conclusions</title>
      <p>Integrating ESG factors at business process level enables organizations to systematically analyze and
trace the sustainability design through a knowledge management lens. By measuring and monitoring
ESG factors at the task level, organizations can identify areas for improvement, ensure repeatability
of ESG processes, or reuse of knowledge assets.</p>
      <p>SMEs face major challenges with aligning their business operations with the ESG criteria, but
support typically comes in the form of software products to aggregate data assumed to be already
available. ESG assessment should be also facilitated internally, through prescriptive methods
allowing organizations to maintain, design and manage the knowledge pertaining to their ESG
policies and risks. Coming from the side of BPM, traditional business process diagrams have a major
use case in annotating times, costs, etc. for process-centric reporting purposes. This can be naturally
extended to incorporate the ESG perspective - not only for documentation purposes, but also in a
machine-readable manner with the help of knowledge graphs that can expose the BPMN-ESG
hybridization. This motivated the objective of our research - to build a method potentially leading to
a knowledge management capability for ESG policies traceable to enterprise architecture elements;
for now, the work was limited to a few BPMN extensions. By applying the “Knowledge Graphs
treatment” to those extensions, it becomes possible to use graph-based techniques (e.g. semantic
queries) for analyzing, and reasoning about business processes, enabling richer insights and
supporting various tasks such as process optimization, and decision support (e.g. identify process
tasks with significant carbon emissions or excessive paper consumption).</p>
      <p>Future DSR iterations will focus on developing a full-fledged DSML that reflects the ESG
specificity more deeply – dedicated task types, event types, document types, circular processes,
taxonomies of knowledge management assets maintained along business operations. In longer term,
we are also considering the use of Large Language Models as a query mechanism over the resulting
knowledge graphs, through hybrid AI configurations such as GraphRAG acting as a knowledge
retrieval mechanism to reduce the reliance on SPARQL and associated technical skills.</p>
