The development of the ROSSIO Thesaurus - Supporting Content Discovery and Management in a Research infrastructure.

The ROSSIO Infrastructure aims at aggregating, organising and contextualising digital objects whose metadata descriptions are provided by a consortium of Portuguese academic, public and private sector institutions in the domains of social sciences, arts and humanities. ROSSIO is the Portuguese representative of DARIAH, the European research infrastructure for arts and humanities. A platform is being developed to provide search and content curation services for researchers and the general public, namely digital collections, digital exhibitions and a virtual research environment. The ROSSIO Thesaurus is being developed to support content discovery and management in the platform. The thesaurus is being modelled as a SKOS concept scheme, and it leverages on existing unstructured vocabularies, such as subject headings and thesauri, produced by the ROSSIO data providers. This paper describes the modelling process of the ROSSIO Thesaurus, its integration and role in the infrastructure, its publication as Linked Open Data, and the results of this work after 6 months of development.
