Common Thesaurus Framework

Co-funded by the Community Programme eContentplusECP-2007-GEO-317007

COMMON THESAURUS FRAMEWORKBASIC IDEA

FRAMEWORK REQUIREMENTS Modularity:

new KOS may be added as a new module plugged in the set of thesauri in the NatureSDIplus solution.

Openness: Each KOS should be easily extendable keeping separated

the original one.Interlinking:

Interlinking among the terms referring to the same concepts in more then one thesaurus in order to harmonize their usage.

Exploitability:encoding in a standard and flexible format in order to

encourage the adoption and its enrichment from third party system

DESIGN PRINCIPLES

SKOS-Simple Knowledge Organization System to encode the thesaurus contentto model basic structure and content of thesauri

according to semantic web\W3C recommendations

Linked data best practicesTo publish the thesaurus in machine

understandable format exploiting existing protocols in the web

LIST OF KOS INCLUDED

THESAURUS FRAMEWORK CONTENT RESULT Number of available concepts

The Thesaurus Framework for Nature Conservation includes more than 200,000 concepts

Thesaurus language All thesauri are in English except for Species in Latin Official languages of other EU countries has been

considered according with the availability translation of the existing thesauri

Interlinks have been generated Habitats to Species and vice versa; EARTh to Bio-geographical regions and vice versa; EARTh to GEMET; Species to official linked data dataset available at the

EUNIS/EEA web site.
