摘要：The article discusses how and to what extent the RDF data model is applied in major Spanish digital collections of heritage materials. This model, as well as Open Data and Linked Data initiatives, are introduced. Fifty-one digital repositories were analysed to determine whether they expressed their records in RDF, offered SPARQL query points searchable by external agents, and used references as property values. The Europeana EDM and OntoWeb models are also described. It is concluded that the use of RDF is unequal and excessively conditioned by the use of applications that automatically convert records into RDF triples. Few of the collections analysed give SPARQL points for external queries. Also, the use of references is linked to applications using different models: EDM or OntoWeb. Collections should enrich their data and define aggregation levels for generated RDF data in order to be disseminated, made accessible, and adapted to the semantic web.
