Data sources
A Data source is a service where published material (metadata and files) are stored, preserved, and made discoverable and accessible. A data source is described by the EOSC Profile for data sources.
- Example:
Episciences is an overlay platform supporting the management of open-access journals on top of the Open Access repository HAL. In this context, episciences.org is a publishing Venue (journal, open access, open peer review), while HAL is a Data source. Articles published via episciences.org will be therefore linked to the respective journal (publishing Venue) and the data source HAL. However, HAL is also a publishing Venue for researchers that are directly uploading their Research product. More specifically, a publishing Venue with peer-review and some support for metadata curation. In this case, a Research product will be linked to HAL both as a publishing Venue and as a Data source.
Note
Each Research product must be associated with its publishing Venue and its Data source.
