Conclusion of the survey
Overall, it seems that Europe is still at the
dawn of metadata management
but several Member States are already working to close the gap between their current modest level and the
one required for them to be effective and efficient in managing
this type of assets.
8
The need for ADMS
Information black holes
Overall it is hard to discover the appropriate schema, code-list or data model at the right moment.
Lack of collaboration, common agreements and consensus
ADMS provides a common way
for publishers to describe their
semantic assets
Information silos
There are still significant differences in the way Member States describe common entities such as an address, a person, a location, etc.
9
The need for federation
How could we promote
reuse of semantic assets
at a European level?
Respect the autonomy of each repository
… by enabling a federation of
semantic assets repositories
Cross-querying and discovery should be supported
10
Federation of Semantic Assets Repositories 2
• The specification: ADMS
• Implementing the federation: Joinup
• Building a Community: CESAR
11
The Asset Description Metadata Schema
(ADMS) is a common way to describe
semantic interoperability assets making it
possible for everyone to search and discover
them once shared through the forthcoming
federation of asset repositories.

Direct benefits Indirect benefits
Federated semantic assets described in a common way
(made possible by the use of ADMS)
Cost savings can be made through:
• better informed ICT purchase decisions
• reuse of semantic assets instead of creating them
More commonality and interoperability
Benefits for users
19
Raise visibility of reusable semantic assets
Federation makes it easier for everyone to discover quickly and for free the appropriate code-list, data model,...

Improve understanding of semantic assets
All federated assets are described in ADMS
Create positive reinforcement of sharing behaviour
Create collaboration and other positive externalities
Benefits for asset publishers
Add value to semantic assets by increasing their User Base

Interviews with Ubitech, GS1 and Listpoint (available on Joinup)
21
“By joining the federation and being among the first to implement
the ADMS specification, Listpoint can receive further international
recognition for its undertakings and get better visibility to its
service and the assets it contains. This will reinforce its role as a
central code list repository for both governmental organisations
and industry” - David Mitton
“GS1 in Europe wants to federate some of the content in its eDox
platform to give more visibility to its work and that of its Member
Organisations. In time, GS1 in Europe considers better aligning its
internal data model with ADMS, for example at the level of the
taxonomies.” - Douglas Hill
“Describing the ICCS’s XML Schemas as semantic
interoperability assets the organization will gain advantages
divided into two main axes:
• Organization’s publicity, visibility and dissemination of its work:
• Allow countries to provide mappings from their legacy/national
models to ICCS model” - Dimitris Alexandrou
...and more to come

• Implementing the federation: Joinup
• Building a Community: CESAR
23
CESAR The Community of European
Semantic Assets Repositories
Bring together semantic assets repository
representatives, national e-Government policy
makers and e-Government professionals to:
Disseminate good practices on metadata management
Encourage Member States to set policies, processes, and infrastructures
for metadata management
Discuss and build common grounds for the future federation of semantic
assets repositories
Business cases on Semantic Assets
Repositories will soon be available
