  1. 1. Financial Regulation Ontology Tutorial “Alignment of Legal and Finance is the foundation for our Semantic Web approach to compliance.” Jurgen Ziemer, Jayzed Data Models Inc., https://finregont.com
  2. 2. 2 Compliance overwhelms Financial Institutions https://finregont.com © Jayzed Data Models Inc. 2016 The regulatory regime for Financial Institutions and Funds has tightened worldwide: US Banks are subject to Capital Adequacy, Holding Company and Prudential Standards regulations. The Dodd Frank Act brought Hedge Funds under supervision of the Securities & Exchange Commission . European countries implemented the Alternative Investment Manager Directive. Increasing complexity Conventional compliance architecture is entangled in numerous systems, transformations, and mappings. At major banks each new compliance program brings more systems, software, warehouses, and literally hundreds of Word documents, spreadsheets, and PowerPoints. Hundreds of people compiling heterogeneous artifacts1 and try to main consistency between them. Neither the business, nor regulators have trust and proof that the code accurately implements the logic of the rules, and that reported numbers accurately trace back to their data sources. more systems, artifacts and staff Consolidated Life New York offices, 1960. (Jack Lemon in Billy Wilder’s “The Apartment”)
  3. 3. 3 Bio and Medical domain have mastered complexity https://finregont.com © Jayzed Data Models Inc. 2016 The human genome contains some 30,000 genes, approximately 3 billion DNA base pairs. Genes direct the production of over a million analyzed proteins. More than 9500 terms define human phenotype anomalies, which describe over10, 000 diseases. Medical service providers exchange detailed clinical information. Almost half a million drugs are approved for treatment. Bio/Medical is more complex than Finance The Semantic Web is the evolution from the old web of documents to a web of data that enables computers to navigate content and derive information. The GENE ontology project started in 1998 with yeast and fruit flies. “Our vision is that all biomedical knowledge and data are disseminated on the Internet using principled ontologies in such a way that the knowledge and data are semantically interoperable and useful for furthering biomedical science and clinical care.” (National Center for Biomedical Ontology1 (NCBO) Today, the NCBO’s BioPortal alone lists 530 ontologies with millions of classes. Research, clinical and increasingly medical information is stored and published in a homogeneous way. Semantic Web and Ontology 1 http://www.bioontology.org/about-ncbo
  4. 4. 4 Finance can master the compliance challenge. https://finregont.com © Jayzed Data Models Inc. 2016 Financial data, regulations, reports, and metadata can be stored in a uniform way. The Ontology Web Language (OWL) defines the semantics of concepts, their relationships, and axioms. Compliance crosses the domains or Finance and Legal. We select the best domain reference ontologies. 2 http://www.edmcouncil.org/financialbusiness 3 http://www.estrellaproject.org/ “The Financial Industry Business Ontology (FIBO) is a collaboration between the Enterprise Data Management Council (EDMC) and the Object Management Group. The EDMC leads design in collaboration with major Financial Institutions. OMG provides governance and publishes FIBO as a formal standard.”2 “The Legal Knowledge Interchange Format (LKIF) models legal rules of the kind found in legislation and regulations.”3 We populated LKIF with the Code of Federal Regulation (CFR) and the United State Code (USC). We populated LKIF with Code of Federal Regulations and US Law. The Financial Regulation Ontology (FRO) extends and aligns the two domain reference ontologies. Extensions define subclasses to specific financial and regulatory data. Ontology Alignment establishes the relationship of equivalent concepts in FIBO and LKIF. It enables queries and reasoning across the domains.
  5. 5. 5 Tutorial sections for specific use cases. The Securities and Exchange Commission (SEC) provides the investors with Adviser data in XML. Publication in OWL on a semantic endpoint would serve the public even better and facilitate queries across other information sources. The tutorial introduction explains ontology fundamentals. Chapter II “Loading the Law” explains, how to design ontology classes and how extract, transform and load data from the XML. The fund’s compliance officer can populate forms using inference and SPARQL rules. The RDF database of the fund holds internal financial data, positions, investors, structure. Chapter III shows ontology inference and rules in practice. The fund manager monitors compliance and can assess the impact of changes to fund structure, investments and client base. Chapter I has a Finance example based ontology primer and business overview of the reference ontologies.. Note: The Use “Load RDF Database is not covered in this tutorial. We highly recommend Cure/Blin RDF Database Systems (2015).

  6. 6. 6 The first chapter introduces Ontology Web Language (OWL) to business and the beginning ontologist. The example “Black Rock manages Emerging Markets ETF” is a good introduction to FIBO. Getting Started continues with step-by-step instructions for Ontology Editor, Protégé and Query tools. FRO foundations explains the core classes relevant to regulatory compliance. The chapter shows how to populate FRO from XML files for law and regulations. The details of LKIF Legal Document are mainly for government agencies, who want to make correction or add more regulations and laws. However, loaded content is basis for Legal reasoning in chapter three and process and design is similar for all data sources. All metadata, mapping, and lineage are stored within the ontology Inferencing is the process to derive new knowledge from asserted facts. The FRO example infers, whether an Investment Funds must register with the Securities & Exchange Commission (SEC). We start with a deep-dive into LKIF Legal Expressions and how FRO defined classes encode SEC mandate and exceptions. https://finregont.com © Jayzed Data Models Inc. 2016 2 Loading the law 3 Legal Reasoning1 Introduction Implementing Financial Regulation Ontology This slide-doc tutorial explains FRO, LKIF and FIBO design, and how to extend the ontologies for data population. We recommend to study the text end-to-end. Even beginner sections show finance related classes and data.
  7. 7. 7 FRO Chapter I – Introduction The Resource Description Framework (RDF) uses an elementary grammar to define a cell of information. Subject Predicate Object Black Rock manages the iShares MSCI Emerging Markets ETF. Both are web resources identified by a URI. The Object Property “manages” connects the two resources. This is similar to creating • an association between objects. E.g. associating two Java instances. • a Foreign Key reference between two database records. :Black_Rock_Fund_Advisers rdf:type fo-fr:InvestmentAdviser ; :hasBusinessName “BLACKROCK FUND ADVISORS”^^xsd:string ; :hasIncorporationDate “1984-11-15T00:00:00″^^xsd:dateTime ; fibo-fnd-rel-rel:manages :iShares_MSCI_Emerging_Markets_ETF ; rdfs:label “Black Rock Fund Advisers”^^xsd:string ; The Data Property assigns a value to the subject resource. Here is the Ontology Web Language (OWL) code. The colon separates the Namespace from the resource name. rdfs:label – a build in RDF data property fibo-fnd-rel-rel:manage – an object property defined in the Financial Services Business Ontology (FIBO). https://finregont.com © Jayzed Data Models Inc. 2016
  8. 8. 8 Triples define the schema OWL classes specify sets. A FIBO class defines Management Companies. FRO has a class for Investment Advisers. RDF Schema (RDFS) extends RDF to allow describing taxonomies of classes and properties. We can define data and object properties of the class. The RDFS property’s Domain restricts the type of the subject, Range restricts the type of the object. We can populate the schema with “iShares Emerging Markets is traded on the New York Stock Exchange”. Instances or Individuals are the members of the class. The RDF object property rdf:type asserts that the individual is an instance of the class. E.g. Black Rock is an Investment Adviser. https://finregont.com © Jayzed Data Models Inc. 2016
  9. 9. 9 Triples define hierarchies and taxonomies The RDF-schema property subClassOf enables rich hierarchies of classes. The subPropertyOf build hierarchies of class association: The FRO Investment Adviser is a subclass of a FIBO Financial Service Provider, which in turn is a subclass of Agent in Role. The owl:Thing is the root of all classes. The core difference to object models is the notion of the set rather then class objects. In Java we must explicitly assign Black Rock to be an Investment Adviser and assign it to be a Financial Service Provider. In RDFS/OWL an instance of Investment Adviser is automatically an instance of all the super classes. Likewise, the a logical data model can define a similar subtype/ supertype hierarchy, but in the database we must explicitly insert records and create the foreign keys. RDF Schema (RDFS) extends RDF to allow describing taxonomies of classes and properties. https://finregont.com © Jayzed Data Models Inc. 2016
  10. 10. 10 Metadata is stored in triples. RDFS provides constructs similar to UML class / object and data modeling Entity Relationship models. Modeling tools provide model transformations, import and export between OWL, ER and UML. • Data modelers still need to derive the Physical model from the Logical Model. • Object modelers generate code from UML The ontology already contains schema and data expressed in triples and we can use metadata in our SPARQL queries. Ontology • Class • Sub Class • Data Property • Object Property Entity Relationship • Entity • Subtype • Attribute • Relationship UML Class • Class • Generalization • Attribute • Association SELECT ?investmentadviser ?managementcompany ?FS_provider ?ETF_class WHERE { ?investmentadviser fibo-fnd-rel-rel:manages ?managementcompany . ?investmentadviser rdf:type ?FS_provider . ?managementcompany rdf:type ?class . ?managementcompany rdf:type ?ETF_class . ?FS_provider rdfs:subClassOf fibo-fbc-pas- fpas:FinancialServiceProvider . } [investmentadviser] Black_Rock_Fund_Advisers [managementcompany] iShares_MSCI_Emerging_Markets_ETF FS_provider fo-fr:InvestmentAdviser ETF_class fibo-fbc-fct-fse:ManagementCompany https://finregont.com © Jayzed Data Models Inc. 2016
  11. 11. 11 Class restrictions limit the set of individuals A restriction describes a class of individuals based on the properties that instances of the class participate in. In other words a restriction is a kind of class, just like a named class. Typically, we apply restrictions to narrow down the set of instances from class to subclass. An Investment Manager is an Investment Adviser, who manages some Investment Company. In the ontology editor (Topbraid Composer) we define the existential restriction (some) on the object property. The universal restriction (only) would mean that the adviser manages nothing else but Investment Companies. We can place restrictions on Quantifiers, Cardinalities and even Values. An example of a Value restriction is a Prime Bond with hasRating only ‘AAA’. Our example has Black Rock and Whitingham Wealth as Investment Advisers. TDAmeritrade doesn’t manage funds. https://finregont.com © Jayzed Data Models Inc. 2016
  12. 12. 12 Defined Class drives the Reasoner So far, the class restrictions although more refined than database constraints still depend on the implementation to assert that Black Rock is an Investment Manager and TDAmeritrade is only an Investment Adviser. Changing Investment Manager to a Defined Class will have the Reasoner infer this new knowledge from existing asserted information. We move the class restriction from rdfs:subTypeOf to owl:equivalent class. Now the Investment Manager is defined as the intersection of all Investment Advisers and all things that manage an Investment Company. The Reasoner tool processes class definitions and infers that a particular individual is a member of the class. The class hierarchy now shows the defined classes in blue and we see two inferred instances: Black Rock and Whitingham Wealth. Checking for class subsumption is a key task of the reasoner key differentiator to non-semantic technologies. We formulate complex compliance rules as Defined Classes from class restriction building blocks. For example: The Reasoner places the matching Funds, Advisers, Assets as inferred members of the rule. –> Semantic Regulation Compliance https://finregont.com © Jayzed Data Models Inc. 2016
  13. 13. 13 Semantic Web has 3 main layers URI Unicode XML Namespace RDF RDF Schema SPARQL OWL Logic Rules Proof Trust SyntaxSemanticKnowledge “The Semantic Web is an extension of the current Web in which information is given well-defined meaning, better enabling computers and people to work in cooperation.” Sir Tim Berners-Lee, director or the World Wide Web Consortium (W3C)4 Trust is the firm belief in the integrity, reliability as accuracy of a regulatory filing. Proof is how a statement in a regulatory filing as been derived. What are the underlying sources of Financial Data? What are the rules and regulations applied? In traditional approaches to regulations Business Rules are defined in spreadsheets and documents for human readers. They get mapped and encoded in programs and databases. In order to proof we elevate logic from code to schema. So that a single artifact is understood and validated by both humans and programs. Today’s traditional web provides the basic building blocks to encode text and Uniform Resource Identifiers. XML provides machine readable syntax. Namespaces facility XML-Schema definition, XSD. The Semantic layer build upon the foundation to fulfill requirements for proof and trust. RDF removes ambiguity from XML. Unequivocal it connects two URIs, subject and object with a predicate. RDFS and OWL define classes of RDF resources, association between classes and class restrictions. The ontology Reasoner processes the asserted facts and infers new information. All information in including results and rules can be queried with SPARQL selects. https://finregont.com © Jayzed Data Models Inc. 2016
  14. 14. 14 Three main levels classify ontologies Upper foundation, top-level Core domain Operational sub-domain LowAbstractionHigh SpecificGeneric An upper ontology (aka top-level ontology or foundation ontology) is an ontology which describes very general concepts that are the same across all knowledge domains. Well known core ontologies are BFO, GFO, DOLCE, SUMO and Dublin Core. Wikipedia 5 “The goal of a core ontology is to provide a global and extensible model into which data originating from distinct sources can be mapped and integrated.” (Doerr, Hunter, Lagoze 1) The core ontology applies to a specific domain, such as biology, medical, Legal and Finance. The Operational Ontology is an implementation of a core ontology. It is specific enough to hold source data. HFR is an operational ontology for the sub-domain of (alternative) investment management. https://finregont.com © Jayzed Data Models Inc. 2016
  15. 15. 15 FinRegOnt imports Reference Ontologies In the Semantic Web a ontology must integrate with other ontologies in the domain. It is a standard practice for Data and Object Architects to utilize Reference Models*. The diagram shows the base websites for reference ontologies, FIBO and LIKF and the set of FRO sites. At the center is FinRegOnt, a core ontology integrating legal and financial information. https://finregont.com/ FinRegOnt includes: • Financial Industry Business Ontology (FIBO). http://www.omg.org/spec/EDMC-FIBO/ • Legal Knowledge Interchange Format (LKIF). A core ontology for Legal domain. http://www.estrellaproject.org/ Unfortunately neither FIBO nor LKIF utilize an upper ontology for generic concepts. Thus the diagram places them overlapping Upper and Core.

  17. 17. 17 Financial Industry Business Ontology (FIBO) “The EDM Council is a 501(c)(6) non-profit trade association founded by the financial industry to elevate the practice of data management as a business and operational priority. The Council is a leading advocate for the development and implementation of data content standards and the publication of data management best practices.”7 FIBO is a collaboration between the Enterprise Data Management Council (EDMC) and the Object Management Group. The EDMC leads design in collaboration with major Financial Institutions. OMG provides governance and publishes FIBO as a formal standard. “The Object Management Group® (OMG®) is an international, open membership, not-for-profit technology standards consortium, founded in 1989. OMG standards are driven by vendors, end-users, academic institutions and government agencies. OMG Task Forces develop enterprise integration standards for a wide range of technologies and an even wider range of industries.”8 “FIBO™ is a business conceptual ontology standard providing a description of the structure and contractual obligations of financial instruments, legal entities, market data and financial processes. The primary application of the business conceptual ontology is for data harmonization and for the unambiguous sharing of meaning across data repositories”3 https://finregont.com © Jayzed Data Models Inc. 2016
  18. 18. 18 Legal Knowledge Interchange Format (LKIF) The European project for Standardized Transparent Representations in order to Extend Legal Accessibility (Estrella, IST-2004- 027655) aims to develop and validate an open, standards-based platform allowing public administrations to develop and deploy comprehensive legal knowledge management solutions, without becoming dependent on proprietary products of particular vendors.3 “LKIF is intended to model legal rules of the kind found in legislation and regulations.“9 It is the main deliverable of the ESTRELLA project. LKIF is an Upper and Core ontology. The lead architect, Rinke Hoekstra made the OWL files are available on GitHub: https://github.com/RinkeHoekstra/lkif-core We will cover LKIF implementations for Traffic and Contract law in the chapter on Legal Reasoning. https://finregont.com © Jayzed Data Models Inc. 2016 The Legal Domain has several available reference ontologies. Nuria Casallas, “Legal Ontology Engineering”1 provides a good introduction and comparison. We believe LKIF is the most advanced and strongest for Legal Reasoning.

(see following detail slides) Note the absence of Data Properties and Named Individuals in LKIF. FIBO has some operational elements, data properties and individuals for Currencies, Countries and even the 12 Federal Reserve district banks. The OWL:Ontology bar shows the actual number of OWL files. The high number of symmetric and transitive properties show the high ontological commitment in LKIF. The statistics show the number of elements in the two reference ontologies. https://finregont.com © Jayzed Data Models Inc. 2016

The ratio of Primitive to Equivalent classes show that LKIF has larger Complex layer than FIBO. https://finregont.com © Jayzed Data Models Inc. 2016
  21. 21. 21 First look at schema and data FinRegOnt website has the ontology documentation. Browsable TopBraid report https://finregont.com/fro/html/ PDF in W3C-style* https://finregont.com/fro/html_widoco /index-en.html Protégé is a free, open source ontology editor from Stanford University. It is the most widely used ontology design tool. Many tutorials and extensions (plugins) are available. FinRegOnt schema modules can be queried on CKAN’s Datahub. Follow the link and instruction on the next pages. https://finregont.com © Jayzed Data Models Inc. 2016 Ontology Editor Semantic EndpointDocumentation This section is for the business users and beginning ontologist. To get an understanding of the Financial Regulation Ontology it is best to look at both schema and data. * Thanks to Silvio Peroni for developing LODE Daniel Garijo for developing Widoco – see 6.

  22. 22. 22 Using an ontology editor Topbraid Maestro “TopBraid Composer™ Maestro Edition (TBC-ME) combines world’s leading semantic web modeling capabilities with the most comprehensive data conversion options and a powerful Integrated Development Environment (IDE) for building semantic web and Linked Data applications.”12 This is our main tool. FRO’s XML and Database imports, transformation rules and orchestration are implemented with Maestro. Most screenshots in this tutorial show TopBraid. Protégé Desktop We use Protégé for proofing – to make sure the ontology opens and passes Reasoner integrity checks. Protégé is free and thus the best way to get started. Download Protégé at http://protege.stanford.edu/products.php#desktop-protege and follow the installation instructions http://protegewiki.stanford.edu/wiki/Install_Protege5 . To get familiar with OWL concepts and the tool, we highly recommend the “Pizza” tutorial from Manchester university: http://owl.cs.manchester.ac.uk/publications/talks-and- tutorials/protg-owl-tutorial/ https://finregont.com © Jayzed Data Models Inc. 2016 Ontology editors are applications that assist in the creation or manipulation of ontologies. They also provide an inference engine (Reasoner) and query interface. We use TopBraid, a commercial editor and Protégé for FRO.
  23. 23. 23 First steps with FinRegOnt in Protégé Launch Protégé and select File->Open from URL… The root ontology file https://finregont.com/fro/Investment_Adviser_Act_USC_CFR.ttl Is a good starting point. It is populated with sections from the Code of Federal Regulations and United States Code relevant the Investment Adviser Act. https://finregont.com © Jayzed Data Models Inc. 2016 The tool loads the Investment Adviser Act ontology file and recursively all included ontologies. This may take a few minutes depending on your download speed. The FinRegOnt website fro directory has all ontology files. There are subdirectories for Reference (fro/ref/), Code of Federal Regulations (fro/cfr/) and United States Code (fro/usc/). The Query directory (fro/query/) contains the SELECT statements used in this tutorial.
  24. 24. 24 First steps with FinRegOnt in Protégé https://finregont.com © Jayzed Data Models Inc. 2016 The active ontology tab displays header information, statistics and the list of includes. The Ontology header windows shows the active ontology and it’s Annotations. Here the SKOS definitions of the files. Annotations, are metadata properties attached to ontology, classes and properties. (Everything is a triple) . The Metrics window lists statistics of the active plus included ontologies. The bottom window, Imported Ontologies shows the direct and indirect imports. Investment_Adviser_Act_USC_CFR.ttl includes FRO_CFR_Title_17_Part_275_Section_1-7, a data ontology file with the Code of Federal Regulations.
  25. 25. 25 The Entities tab has windows for class and properties https://finregont.com © Jayzed Data Models Inc. 2016 The entities tab has a navigator window for the class and object hierarchy. Note that all top-level classes, directly under owl:Thing are LKIF. Financial Regulation Ontology extends LKIF with United States Code (USC) and Code of Federal Regulation classes. We will see FRO subclasses of LKIF in the followig pages. Tip: Regulatory Document classes are lkif- expr:Medium. Lawmakers, supervisors are lkif- action:Agent. Expand the “+” sign in the Navigator to drill down.
  26. 26. 26 Ontology modules and prefixes A file will define a namespace for triples defined in the ontology. The prefix abbreviates the namespace. In Protégé select File->Preferences, Render tab and “Render by prefixed name to display the prefix for the Class names. The naming convention is: ontology-module:Name The ontology is “lkif-”, “fibo-” or “fro-”. Navigate down lkif-expr:Medium to expand fro- cfr:CodeFederalRegulations and fro-usc:UnitedStatesCode. The Code of Federal Regulations is a LKIF Regulation; the United States Code is a LKIF Statute. The defined classes fro-leg-ref:DocumentEdition and DocumentComponent enable generic queries on compliance documents. Ontologies LKIF, FIBO and FRO are broken down into modules. The modules contain OWL files. https://finregont.com © Jayzed Data Models Inc. 2016
  27. 27. 27 Class details for CFR Section Drill down and select CFR_Section. The Annotations window shows the class label and definition. The Description window defines CFR_Section as a subclass of CFR_Component and the anonymous class “fro-leg-ref:divides some fro-cfr:CFR_Part.” The Code of Federal Regulations is a hierarchy of Title, Chapter, Section and Paragraph. The divides object property positions Individuals in the hierarchy. The SubClass of (Anonymous Ancestor) axioms inherited from lkif-norm:LegalDocument place the regulation in the wider legal ontology context. It bears a Legal Expression that is a Statement in Writing made by a Legislative Body (the US Congress). The Instances part lists 10 data records imported from the CFR XML file. The namespace has the FinRegOnt.com directory and filename. Click on https://finregont.com/fro/cfr/FRO_CFR_Title_17_Part275.ttl#r- 1-0 https://finregont.com © Jayzed Data Models Inc. 2016
  28. 28. 28 Individual, instance details for CFR §275.0-3 The Section divides Part 275 of the regulation. The object property fro-leg-ref:hasSourceInstance links to the original record in the XML import for this section. The data properties lists hasSectionNumber “§ 275.0-3”, hasSubject “References to rules and regulations” and hasSectionCitation “[30 FR 4129, Mar. 30, 1965]” as defined in CFR. Sequence Number is system generated by the XML import. It is simply the order of elements in the CFR XML file. We use the property to ORDER BY in queries. The Property assertions tab shows Object and Data properties for the section individual. https://finregont.com © Jayzed Data Models Inc. 2016 https://finregont.com © Jayzed Data Models Inc. 2016
  29. 29. 29 Querying FRO instance data SPARQL is a the query language for the Semantic Web, able to select and manipulate data stored in Resource Description Framework (RDF) format. Just like SQL is the query language for relational databases. The Ontology editors have an interface to run SPARQL queries on ontology files. The best book on SPARQL is Bob DuCharme’s “Learning SPARQL”, O’Reily, 2013. Large volumes as data require dedicated database systems. All major database vendors provide add-ons to store RDF. If you already have a license “Oracle Spatial and Graph” can be installed for free. There are also native RDF systems like Open Source Virtuoso and Jena. See Oliver Cure and Guillaume Blin’s “RDF Database Systems”, Morgan Kaufman, 2015 for comparison and excellent treatment of the internals. A Semantic or SPARQL endpoint is a Web protocol service that enables users and applications to query a knowledge base. All RDF Databases provide endpoints. Many well-known information providers have public endpoints. http://wiki.dbpedia.org/ lets you query WIKI information. Governments publish data on Semantic Endpoint. For confidential information the Endpoint is only on the Financial Institution’s intranet. The next pages show FinRegOnt on a CKANS public Endpoint. https://finregont.com © Jayzed Data Models Inc. 2016 RDF Database Semantic Endpoint
  30. 30. 30 FinRegOnt demo Semantic Endpoint “Open Knowledge International is a worldwide non- profit network of people passionate about openness, using advocacy, technology and training to unlock information and enable people to work with it to create and share knowledge.” https://okfn.org/about/ CKAN is a an open source data portal widely used by governments and public services. FinRegOnt is open source and published on the CKAN datahub. https://datahub.io/dataset/financial-regulation-ontology Although not supported CKAN has a DataStore, where samples of the Financial Regulation Ontology can be queried. http://semantic.ckan.net/isparql/ https://finregont.com © Jayzed Data Models Inc. 2016 FinRegOnt is available for query on CKAN’s DataStore Semantic Endpoint. CKANOpen Knowledge
  31. 31. 31 Query FinRegOnt on a SPARQL endpoint https://finregont.com © Jayzed Data Models Inc. 2016 The CKAN endpoint is powered by Virtuoso’s iSPARQL. Launch the CKAN endpoint http://semantic.ckan.net/isparql/ on a web browser and click on the “Advanced” tab. To get started just copy and paste the query “CFR 252 validation complete text (PREFIX FROM).rq” from the FinRegOnt query directory. https://finregont.com/fro/query/CFR%20 252%20validation%20complete%20text %20(PREFIX%20FROM).rq Click on the execute icon. To query FinRegOnt on a Semantic Endpoint, we need to provide FROM information of the graphs
  32. 32. 32 SPARQL query results https://finregont.com © Jayzed Data Models Inc. 2016 The result set shows the record for Code of Federal Regulations Title 12 Part 252 – enhanced prudential standards. You can look up the ontology documentation and explore variations of the query. Columns in the Result tab are binded variables in the query: “?part fro-cfr:hasPartText ?part_text” asks the query engine for all resources that are domain and range of the hasPartText data property. “?section fro-leg-ref:divides ?part” is the object property join from CFR Part to CFR Section. The query asks for hasSectionNumber and hasSectionSubject of the CFR Section. Everything is a Triple!
  33. 33. 33 SPARQL query by example https://finregont.com © Jayzed Data Models Inc. 2016 The QBE tab shows the query’s graph. Arrows depicting the properties connect circles for the variables. The Schema explorer box on the right hand side shows classes and properties defined in the ontologies. In our example Code_Federal_Regulations.ttl graph defines the CFR classes for Title, Volume, Part, Chapter, Sections etc. To modify the query, we drag additional entities into the diagram.
