The SWAD-Europe workplan describes the structure of the overall project. This page provides the current state of the thesaurus activity (WP8).

The SWAD-E Thesaurus Activity Reports Page provides summaries of and links to all the deliverables published as part of this workpackage.


SKOS is an open collaboration initiated by SWAD-E, developing specifications and standards to support the use of knowledge organisation systems (KOS) on the semantic web ... see the SKOS homepage for more information.

RDF representations for thesaurus data

Work is ongoing to develop RDF vocabularies for describing thesaurus data ... see the SKOS Core and SKOS Mapping pages for latest information.

Terminology Web Service API

A web service API for access to a thesaurus service along with a demonstration implementation has been developed as part of this workpackage. The SKOS API is available now along with the demonstrator described below.

Demonstrator for RDF thesaurus technology

A demonstrator has been created, building on the development, implementated as a thesaurus web service, to illustrate the power of thesauri in improving information retrieval - the DREFT SKOS Thesaurus API Demonstrator including server, client and, sample data encoded in SKOS, along with a live web service and live client demonstration calling the service.

Public list of use cases

We are collecting a public list of use-cases for all applications of thesaurus and similar services in distributed environments. These use-cases will be used as the basis for defining a web service API for access to a thesaurus service.

We invite you to contribute to this list. Anything from an anecdotal description to a formally defined use-case is welcome. Email your use-case to Nikki Rogers at ILRT.
