Federating specialized digital libraries

The paper describes a procedure for creating a joint thesaurus of Architectural Heritage (AH) based on existing ones. After surveying the most important repositories of historic architectonical information and the associated thesauri, the design of a multilingual framework incorporating the different thesauri is presented and discussed. Also a system to perform semantic queries on these architectural databases is briefly presented. The implementation is based on the combination of existing technology, such as SKOS, RDF, Linked Data and semantic queries.
