Introduction and Background

The ISA Programme
Digital Agenda for Europe - Barriers
Semantic Interoperability in the
European Interoperability Framework
Political context
Cooperating partners with compatible visions,
aligned priorities, and focused objectives
Legal interoperability
• Aligned legislation so that exchanged data is
accorded proper legal weight
Organisational
Interoperability
• Coordinated processes in which different
organisations achieve a previously agreed and
mutually beneficial goal
Semantic
Interoperability
• Precise meaning of exchanged information
which is preserved and understood by all parties
Technical
Interoperability
• Planning of technical issues involved in linking
computer systems and services

What is “Semantic Interoperability”
How to ensure semantic interoperability
6
Semantic Standards
Semantic Standards = common ways to describe information
• Generic data models
• Reference data (e.g. codelists, taxonomies, dictionaries, vocabularies)
Sharing and Reuse of semantic standards contributes to:
a) Reduce development costs, not reinventing the wheel
b) Reduce integration, and sharing of information costs
c) Increase interoperability between systems

ADMS & Catalogue of
semantic standards
How to increase visibility of semantic standards
A large number of semantic standards already exists
These are scattered in numerous places linked with various
initiatives
–
Several national initiatives to create repositories/libraries/catalogs
of semantic standards (e.g. Germany, Denmark, Finland, Estonia…)
–
Standardization bodies and third party initiatives generate valuable
and highly reusable specifications (e.g. OASIS, W3C, UN/CEFACT…)
–
Independent projects make available semantic standards to their
own websites
How could we promote reuse at a European level?
The need for federation
How could we promote use of semantic standards at a
European level?
… by increasing the visibility of what already
exists
…enabling a federation of semantic standards
repositories
–
Cross-querying and discovery should be supported
–
Respect the autonomy of each repository
How to federate?

standards

• May 2012: Endorsed by the EU member states (ISA
Coordination Group)

ADMS-based federation of
semantic standards repositories
Catalogue of semantic
standards
• 1800+ semantic standards from 22 repositories are
currently searchable through Joinup
• Semantic standards are described using ADMS
• Features simple and advanced search of semantic standards

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

Pilots
using Linked Data technologies
5 Linked Data pilots featuring the
Core Vocabularies
1) Interconnecting Belgian address data using the
Core Location Vocabulary
– In collaboration with AGIV, CIRB, bpost, FEDICT, SPW, NGI /IGN
and EC INSPIRE team.
– Pilot available at: http://location.testproject.eu/BEL/
2) Linking national plant protection products
registers
In collaboration with DG SANCO and agencies from 8
Member States, i.e. Austria, Belgium, Germany, Greece,
Hungary, Poland, The Netherlands and Sweden.

Guidelines & good
practices
Guidelines & good practices
rules
10
URIs
for persistent
Follow the pattern
e.g. http://{domain}/{type}/{concept}/{reference}
Re-use existing identifiers
e.g. http://education.data.gov.uk/id/school/123456
Link multiple representations
e.g. http://data.example.org/doc/foo/bar.html
e.g. http://data.example.org/doc/foo/bar.rdf
Implement 303 redirects for
real-world objects
Avoid stating ownership
e.g. http://education.data.gov.uk/ministryofeducation/id/school/123456
Avoid version numbers
e.g. http://education.data.gov.uk/doc/school/v01/123456
Avoid using auto-increment
e.g. http://education.data.gov.uk/id/school1/123456
e.g. http://education.data.gov.uk/id/school1/123457
Avoid query strings
e.g. http://education.data.gov.uk/doc/school?id=123456
Use a dedicated service
i.e. independent of the data originator
e.g. data.gov.uk and publications.europa.eu are decoupled from
specific government department and could readily be transferred and
run by someone else if necessary.
Avoid file extensions
http://education.data.gov.uk/doc/schools/123456.csv

Conclusions - Challenges
Conclusions
• Technical standards have contributed to mature solutions at the
technical interoperability layer
• Semantic standards are still missing to address semantic
interoperability
• The EC ISA Programme has initiated work in this area
Challenges
Open Challenges
• Freedom versus regulation: Over-specification versus
lean start-up and minimum viable product approaches.
• Which process for creating semantic standards: Roles
for standardization bodies, governments, markets,
communities.
• How to align and promote the (re)use of semantic
standards: Alignment, internationalization
