The Semantic Puzzle

ADMS implemented in PoolParty Thesaurus Manager (PPT) 3.1.0 Release

ADMS – the Asset Description Metadata Schema of the European Commission Joinup Initiative, is a metadata vocabulary to describe semantic interoperability assets.

The Asset Description Metadata SchemaADMS, the Asset Description Metadata Schema, is a profile of DCAT for describing so-called Semantic Assets (or just 'Assets'), that is, highly reusable metadata (e.g. xml schemata, generic data models) and reference data (e.g. code lists, taxonomies, dictionaries, vocabularies) that are used for ...

One of the main objectives of ADMS is e.g. to foster cross-boarder services in EuropeEurope is, by convention, one of the world's seven continents. Comprising the westernmost peninsula of Eurasia, Europe is generally divided from Asia to its east by the water divide of the Ural Mountains, the Ural River, the Caspian Sea, the Caucasus Mountains, and the Black Sea to the ... by the efficient re-use of semantic assets in e-Government.


Description of ADMS
ADMS will allow public administrations, businesses, standardisation bodies and academia to:
  • keep their own system for documenting and storing semantic assets;
  • improve indexingAutomatic indexing is the ability for a computer to scan large volumes of documents against a controlled vocabulary, taxonomy, thesaurus or ontology and use those controlled terms to quickly and effectively index large document depositories. As the number of documents exponentially increases ... and visibility of their own assets;
  • describe semantic assets in a common way so that they can be seamlessly cross-queried and discovered by the community through a single access point (Joinup);
  • retrieve, compare and potentially link semantic assets to one another in cross-border and cross-sector settings;
  • identify assets to be reused avoiding duplication and expensive design work.

Outreach of ADMS
ADMS is the first step towards a federation of european assets repositories. From mid 2012, Joinup will make available a large number of semantic interoperability assets, described using ADMS, through a federation of asset repositories of Member States, standardisation bodies and other relevant stakeholders. Through this federation, semantic interoperability assets will become retrievable and available via a single point of access.

Please consult the ADMS brochure for further information.


ADMS implemented in PoolPartyWeb based ontology manager which can serve as a central hub for your knowledge organization. With PoolParty you can organize and maintain knowledge models based on widely accepted specifications like RDF, SPARQL and SKOS.

The largest thesaurus in the world is the Historical Thesaurus of the Oxford English Dictionary, which contains more than ... Manager (PPT) 3.1.0 Release


The current release 3.1.0 of the PoolParty Thesaurus Manager (PPT) of the Semantic Web Company provides now full ADMS capability!

They are used in subject indexing schemes, subject headings, thesauri and taxonomies. Controlled vocabulary schemes mandate the use of predefined, authorised terms that have been preselected by the designer of ...

Thesaurus) – means the meta data of a controlled vocabulary – following now also ADMS standards – these ADMS relevant meta data is automatically published with a controlled vocabulary using the ADMS RDF schema and thereby can be used to publish a vocabulary in the repository of Joinup or another relevant repository of semantic assets to ensure re-use of the controlled vocabulary and thereby interoperability for services et al.
