The national infrastructure consists of four university repositories and a national portal (http://openscience.si/) that aggregates content from the university repositories and other Slovenian archives in order to provide a common search engine, recommendation of similar publications, and similar text detection. The Slovenian open access infrastructure dataset comprises of metadata and author data of diploma, master and doctoral theses and research publications of Slovenian universities and other Slovenian archives (dLib.si, Videolectures.NET, DKOMORS, repository SciVie...). The dataset is available in n-triples, RDF/XML and CSV format. Metadata from dataset is also accesible via the web interface. Each query returns a JSON object with a variable amount of properties (depending on the metadata available and the type of request).
