The European context and
the need for Core
Vocabularies
I.T.
The ISA Programme undertakes a number
of initiatives to promote interoperability
European Interoperability Framework
Political context
European Interoperability Framework
• 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.
Core vocabularies
https://joinup.ec.europa.eu/node/43160
Simplified, reusable, and
extensible data models that
capture the fundamental
characteristics of a data entity
in a context-neutral fashion.

The Core Location Vocabulary
I.T.
Core Location Vocabulary
• A simplified, reusable and extensible data model
that captures the fundamental characteristics of a
location, represented as an address, a geographic
name, or a geometry.
• Developed in the period December 2011 – May
2012 by a multi disciplinary Working Group
Core Location Vocabulary
• co-chairs: Michael Lutz, Paul Smits, Andrea Perego (DG
JRC)
• editor: Phil Archer (W3C)
• task force: Segun Alayande, Adam Arndt, Joseph
Azzopardi, Chirsina Bapst, Serena Coetzee, Andreas
Gehlert, Giorgios Georgiannakis, Anja Hopfstock, Andreas

W3C Location and Address Community
• The W3C Location and Addresses Community
Group is to review the existing efforts such as the
Core Location Vocabulary and assess whether
any use cases would be served by harmonization
and/or new standardization work.
• It may produce specifications or use cases and
requirements documents, which may be proposed
for adoption by the W3C Government Linked Data
(GLD) Working Group
INSPIRE data specifications
• Core Location can be seen as a subset of the INSPIRE
address specification as it based on the INSPIRE
AddressRepresentation class.
• INSPIRE XML versus Location RDF
representation.
• The Location CV and INSPIRE are complementary
• A linked data service can be implemented on top
of an INSPIRE representation.
