What is this talk about? Semantic interoperability • a roadblock to the realisation of the European Single Market Semantic standards and how can they help you • e-Government Core Vocabularies • DCAT Application Profile for Data Portals in Europe • The Asset Description Metadata Schema • Finding semantic standards on the European Federated Interoperability Repository Reusing semantic standards Your feedback & questions
What is a semantic standard? Semantic standards are commonly-agreedstructural metadata, e.g. data models and reference data. • See also: V. Peristeras. Semantic Standards: Preventing Waste in the Information Industry, IEEE Intelligent Systems, July-Aug. 2013 (vol. 28 no. 4) pp. 72-75 • http://www.computer.org/csdl/mags/ex/2013/04/mex2013040072-abs.html
What is semantic interoperability? A plant A plant Semantic interoperability is the ability of organisations to process information from external sources in a meaningful manner, such that the precise meaning of exchanged information is understood and preserved throughout exchanges between parties. • Source: European Interoperability Framework • http://ec.europa.eu/isa/documents/isa_annex_ii_eif_en.pdf
Facts • Semantic interoperability requires consensus on semantic standards for information exchange. • Semantic interoperability is fostered by the sharing and reuse of semantic standards. • Sharing and reuse of semantic standards reduces the cost of information exchange across borders and organisations.
The ISA Programme on semantic standards In the context of Action 1.1 on improving semantic interoperability in European eGovernmentsystems (SEMIC), the ISA Programme has initiated the development of: • The e-Government Core Vocabularies • The DCAT Application Profile for data portals in Europe (DCAT-AP) • The Asset Description Metadata Schema (ADMS) Visit us at http://semic.eu
Building agreements All semantic standards developed by the ISA Programme were developed following a consensus building process: • Involving international Working Groups of experts; • Following a formal open process and methodology – based on the one followed by the W3C. • Foreseeing public review periods • Re-using existing standards Core Person, Core Location, the Registered Organization Vocabulary and ADMS were initially developed by the ISA Programme and have now been taken over by W3C – discussed in the late W3C GLD.

The e-Government Core Vocabularies Simplified, re-usable, and extensible data models that capture the fundamental characteristics of a data entity in a context-neutral fashion. Source: https://joinup.ec.europa.eu/node/43160 Slide 10
3 generic use cases • Harmonised access to base registers (basic public service) • Interoperable cross-border public services (aggregate public service) • Interoperability of public data: making it easier to mash up public data Source: http://ec.europa.eu/isa/documents/isa_annex_ii_eif_en.pdf
The e-Government Core Vocabularies 3 representation formats XML schema Conceptual model RDF schema Re-uses Core Components Technical Specification (CCTS) and UBL NDR Re-uses existing RDF vocabularies Re-usesexisting concepts in CCL, INSPIRE, etc. IPR ISA Open Metadata Licence v1.1 Maintained by W3C (Government Linked Data Working Group)
The DCAT-AP • A common vocabulary for describing datasets hosted in data portals in Europe, based on the Data Catalogue vocabulary (DCAT). • It enables cross-portal search for datasets. • As an application profile of DCAT, the DCAT-AP • Defines mandatory, recommended an optional classes and properties • Recommends a number of controlled vocabularies for assinging values to properties, e.g. Eurovoc for dcat:theme.

The DCAT-AP The DCAT-AP facilitating the development of the pan-European data portal
ADMS • A common vocabulary for representing semantic standards • ADMS allows public administrations, businesses, standardisation bodies and academia to: • describe semantic standards in a common way so that they can be seamlessly cross-queried and discovered by developers from a single access point; • keep their own system for documenting and storing semantic standards and still be interoperable with others; • improve indexing and visibility of their own standards; • link semantic standards to one another in cross-border and cross-sector settings. • ADMS evolved into a W3C Working Group note based on DCAT.

Reusing semantic standards Re-use by extension: 3 levels of abstraction RDFS /OWL XML Schema representation techniques UML model … Message level Domain level Levels of abstraction Core Vocabularies Core level
Example of reuse Example of reuse by extension: defining Patient as a subclass of Core Person
Example of reuse OSLO: Open Standards for Local Administrations • Putting the core vocabularies into a local context – in Flanders, Belgium. • Local administrations need locally enriched data models and data.

Open Data Support • Aims to improve the visibility and facilitate the access to datasets published on governmental Open Data portals in order to increase their reuse within and across borders by providing a single point of access to metadata descriptions of datasets homogenised using the DCAT-AP. • Visits us at opendatasupport.eu • Benefit from our online training service on Linked Open Government Data at training.opendatasupport.eu ODIP Pan-European Data portal
Conclusions • Public administrations should become aware that semantic standards are an important asset for eGovernment systems development. • Public administrations should identify and document semantic standards with reusepotential for developing eGovernment systems. • Public administrations should make their semantic standards open for reuse. • Public administrations should provide their semantic standards both in human and machine-readable formats.
Conclusions • Whenever possible, definitions of semantic standards should reuse existing specifications to avoid duplication of work and overlaps. • For example, we showed how the e-Government Core Vocabularies can 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.
