Bulgarian Portal for Open Science
The Bulgarian Portal for Open Science is multidisciplinary and welcomes doctoral dissertations and peer-reviewed manuscripts or published versions of scientific publications created by researchers. The items need to be described by a mandatory set of metadata: author/s, title, publication date, resource type (e.g. journal article, part of a book, conference paper, report, etc.), resource identifier (e.g. DOI, Handle), access rights (open, metadata only, restricted, embargoed access). The system also performs selective metadata harvesting from Bulgarian institutional repositories with open access that support the Open Archives Initiative Protocol for Metadata Harvesting. It is also integrated with the national database for doctoral dissertations in the Register of academic staff.
