e-SENS WP6.2 face-to-face meeting, Poznan, 24 October 2013 ISA Programme Action Semantic Interoperability e-Documents based on reusable core assets such as core vocabularies

Outline 0. ISA Programme Action What are the Core Vocabularies? 2. Why using the Core Vocabularies? 3. How to use? 4. Where already used? 2

“Standards are like toothbrushes, a good idea but no one wants to use anyone else's” - Anita Golderba

Questions raised so far during this meeting… Which building block types: methodology, library, NDR, tools …? Reuse by restriction/extension? Syntax vs Semantics? Governance mechanism and sustainability? Metadata management? Reuse existing tools… exchange data elements between tools? Does it matter at all? (mediation) Do libraries cover everything? … And how about RDF?

ISA undertakes initiatives to foster interoperability of information exchanges by public administrations What is interoperability? Ability of disparate organisations to interact towards mutually beneficial and agreed goals, involving the sharing of information and knowledge 5

Political context European Interoperability Framework 6 Source:

ISA Action 1.1 Semantic Interoperability New Work Package: Define a Method to build e-Documents based on Core Assets Methodology e-Documents Core Assets (Building Blocks)

Methods Examples: CCTS NIEM Naming and Design Rules (NDR) UBL ISA Core Vocabularies

e-Documents Definition? Machine-readable? PDF? XML? Messages?

Core Assets UN/CEFACT Core Component Library UBL 2.1 Library ISA Core Vocabularies

Why we should collaborate What is e-SENS CC6.2 doing? "Develop Semantic Assets" What is a Semantic Assets?

D6.1 chapters Stock taking from predecessor LSP – Building Blocks Methodology SWOT analysis Maturity Semantic tools Requirements for semantic interactions EIA description of Building blocks Overview of semantic assets in Europe Priorities, Plans

Types of Semantic Assets (D6.1) Schemas (Messages, eDocs, …) Knowledge organization systems: o Codelists, Catalogues, (Controlled) Vocabularies o Taxonomies, Thesauri, Name authorities Ontologies Mappings/Translations, Mapping Services Other Services (Syndication, Service Catalogue, Directory of Registers) Process flows Containers

Future plans for CC 6.2 Create? Reuse? What is reusable? What is generic?

Thank you for your attention

Building consensus on core vocabularies 2 WGs with each 60+ members 21+ EU Member States Following a formal process and methodology Public review periods Re-using existing standards 19 Source:

Core vocabularies Simplified, re-usable, and extensible data models that capture the fundamental characteristics of a data entity in a context-neutral fashion. 20 Source:

4 core vocabularies 21 Fundamental characteristics of a person. Fundamental characteristics of a legal entity, such as legal identifier, name, company type, activities. Fundamental characteristics of a location, represented as an address, a geographic name, or a geometry. Fundamental characteristics of a public service.

3 representation formats RDF schema Re-uses existing RDF vocabularies ISA Open Metadata Licence v1.1 IPR Re-uses Core Components Technical Specification (CCTS) and UBL NDR XML schema Conceptual model Re-use existing concepts in CCL, INSPIRE, etc. Maintained by W3C (Government Linked Data Working Group) 22

Core Vocabulary UML Model 23 A conceptual model of the Core Vocabularies To enable humans to understand the meaning of the data model Not (yet) used for model-driven design of schemas

Illustration: Core Person UML model 24

Core Vocabulary XML Schemas According to OASIS Universal Business Language (UBL) XML Naming and Design Rules (NDR) Garden of Eden design pattern (maximising reuse of global elements) Using Crane Software Genericode-to-UBL-NDR scriptGenericode-to-UBL-NDR Location XML Schema as subset of the INSPIRE Data Specifications (GML Application Profile)? 25

Core Vocabularies RDF Schemas Maximally reuse existing foundational RDF Vocabularies: Dublin Core Terms, FOAF, SKOS, … Created with a text editor Core Location as a foundational RDF Vocabulary for the INSPIRE Data Specifications? 27

This attribute also carries prefixes or suffixes which are part of the Family Name, e.g.... en. foaf:name rdfs:comment ; rdfs:isDefinedBy ; rdfs:label ; dcterms:identifier ; vann:usageNote "The full name contains the complete name of a person as one string.

3 generic use cases 1. Harmonised access to base registers (basic public service) 2. Interoperable cross-border public services (aggregate public service) 3. Interoperability of public data: making it easier to mash up public data 30

Recommendation 12. Public administrations, when working to establish European public services, should develop interfaces to authentic sources and align them at semantic and technical level. European Interoperability Framework 31 Source:

Denmark: “Good basic data for everyone” 32

How to use the e-Government Core Vocabularies? Reuse the core vocabularies as semantic building blocks for information exchange Reuse-by-restriction: use only a subset of the Core Vocabularies (e.g. only locn:Address) Reuse-by-extension: use the Core Vocabularies as a foundational data model that is extended with context-specific elements 34

Re-use by extension: 3 levels of abstraction e-Documents Linked Data, e-Documents (?) e-Documents domain models domain vocabularies domain schemas 35 Core level Message level Domain level RDFS /OWL XML Schema Core Vocabularies representation techniques … Levels of abstraction UML model

Core public service vocabulary Describe public services “only once” using a standard vocabulary, make machine-readable descriptions available to others so that they become searchable on many governmental access portals. Core Public Service Vocabulary 45

Public services in Europe 46

Flemish Intergovernmental Product and service catalogue (IPDC) Exchange of service catalogue data between national, regional, and local governments. REST web service that returns XML. XSLT to convert into Core Public Service.XSLT Project manager: Katrien De Smet, CORVE (present at SEMIC 2013!) 47 n/lokaal/IPDC/

OSLO: Open Standards for Local Administrations 48 Putting the core vocabularies into a local context. Local administrations need locally enriched data models and data.

OpenCorporates: basic company data for everyone Machine- readable data: (URI, legal identifier, name, company type, activities) Links back to the base registers 49

Conclusions The core vocabularies are used in many different contexts. They can easily be extended and integrated with other vocabularies. They can be adapted to your needs and context. The can be used both in an XML and an RDF world. 50
