Abstract:In the context of the wide research environment we introduce the CERIF (Common European Research Information Format) data model which (a) has a richer structure than the usual metadata standards used in research information; (b) separates base entities from link entities thus providing flexibility in expressing role based temporal relationships; (c) defines a distinct semantic layer so that relationship roles in link entities and controlled value lists in base entities are separately managed and multiple vocabularies can be used and related to each other; (d) can generate the common metadata formats used in research information. CERIF is used widely and is an EU Recommendation to Member States. At the request of the European Commission, CERIF is maintained, developed and promoted by euroCRIS.

This paper introduces a transformation engine which can be used in order to convert an existing institutional repository installation into a Linked Open Data repository. We describe how the data that exists in a DSpace repository can be semantically annotated in order to serve as a Semantic Web (meta)data repository. We present a non-intrusive, standardscompliant approach that can run alongside with current practices, while incorporating stateof-the art methodologies. Also, we propose a set of mappings between domain vocabularies that can be (re)used towards this goal.

Abstract. The OpenAIREplus project aims to further develop and operate the OpenAIRE e-infrastructure, in order to provide a central entry point to Open Access and non-Open Access publications and datasets funded by the European Commission and National agencies. The infrastructure provides the services to populate, curate, and enrich an Information Space by collecting metadata descriptions relative to organizations, data sources, projects, funding programmes, persons, publications, and datasets. Stakeholders in the research process and scientific communication, such as researchers, funding agencies, organizations involved in projects, project coordinators, can here find the information to improve their research and statistics to measure the impact of Open Access and funding schemes over research. In this paper, we introduce the functional requirements to be satisfied and describe the OpenAIREplus data model entities and relationships required to represent information capable of meeting them.
