Abstract
The RNPLS&T’s Single Open Information Archive (SOIA) under construction supports the functionality of open access repository. To provide interoperability, the metadata describing the SOIA objects are rendered to external information systems in various formats using OAI-PMH and SRU/SRW [1, 2] technologies.The open access repositories support Dublin Core metadata. Besides, MARCXML, ORE, RDF metadata are also among the supported schemes for some program implementations, however, their presence is quite limited. The OAI-PMH proprietary software used in SOIA enables to expand the completeness of metadata, in particular, for integration with promising technologies, e. g. semantic networks and linked data.The authors analyze the match between SOIA subject headings and concepts of GEMET thesaurus built within SKOS model and RDF. Terms interpretation within the thesaurus is one of SKOS functions. Despite the relatively quantitatively low intersection of SOIA headings and GEMET concepts, the identified matchings enrich SOIA information model. The authors suggest the extended model for RDF presentation of SOIA objects.
