The release of the ISO standard for thesauri “ISO 25964 Part 1: Thesauri for information retrieval” in 2011 was a huge step, as it replaced standards that dated back to 1986 (ISO 2788) and 1985 (ISO 5964). By that, methodologies from a pre-Web era, when thesauri where rather developed to be published on paper have been further developed. The new standard also brought a shift from a term-based model to a concept-based model stating: “Each term included in a thesaurus should represent a single concept (or unit of thought)” – from: ISO 25964 Part 1, page 15. That brings it close to Semantic Web based data models like SKOS and also shows that formerly disconnected communities are now working together.
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.
- keep their own system for documenting and storing semantic assets;
- improve indexing 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.
