OPTIMETA - Strengthening the Open Access publishing system through open citations and spatiotemporal metadata

The OPTIMETA project strengthens the Open Access ecosystem by transferring citation information and spatiotemporal metadata from Open Access journals to openly accessible data sources. A contribution is made to the metadata omnipotence by adding crucial functionalities to Open Journal Systems (OJS) as the most widely used open source software for publishing scientific journals. In this way, the aforementioned metadata can be collected, used by oneself and shared with others. The combination of open source and open data enables journals to offer their respective subject communities innovative services for semantically significant linking of articles via geodata and to contribute to open citation graphs such as COCI (OpenCitations Index of Crossref open DOI-to-DOI). Both provide better visibility and thus findability of publications in various ways, which in turn increases the attractiveness of the respective open access (OA) journals as publication venues.
