The situation
• a 30 year-old thesaurus
• 40 000 terms in almost twenty languages
AGROVOCthesaurus
• Evolving through the decades by a changing, global group of institutions and terminologists
• Control over time shifting across geography and management structures
Born in an era of paper-based
research
• Used by information centers around the world
• The only globally important agri-thesaurus
An indexing standard
SemTech 2011, Yves Jaques, FAO of the UN 3
The information revolution
• AGROVOC moved to an OWL model in 2005.Semantic web
• SKOS-version released
• Over 18 000 alignments to other major thesauriLinked open data
• Library of Congress Subject Headings / Rameau
• National Agricultural Library Thesaurus
• Eurovoc / GEMET / STWAlignments

But how to maintain AGROVOC and better yet…
keep it growing?
The opportunity
Rethink how to manage AGROVOC
Embrace new frameworks
Leverage existing components and libraries
SemTech 2011, Yves Jaques, FAO of the UN 5
The work
Remodel using semantic standards, OWL then SKOS
Decentralize maintenance and evolution
Use standard platforms, e.g. web browser
Leverage existing components, e.g. GWT, Lucene, Protégé API
Hide model’s true complexity
Include the publishing workflow

Issues
Some scalability issues
(AGROVOC has 40 000 concepts in to 20 languages)
Rich GUI requires high-bandwidth connection
Not yet fully SKOS-compatible
(v2.0, late Summer 2011)
SemTech 2011, Yves Jaques, FAO of the UN 23
