The DiscoverEd project is a scalable search of educational resources with a special emphasis on Open Educational Resources (OER). As such, it utilizes a web-wide index, promoting results which have been identified as OER. DiscoverEd.creativecommons.org is serving as an aggregation point for other organizations which have identified or produced OER.
Data are aggregated from several sources, including:
- RSS and Atom feeds (title, description and subject information)
- OAI-PMH repositories (OAI-DC metadata)
- Crawled pages (embedded RDFa)
You can read more details about our metadata specifications. The aggregated information, along with source annotations, is stored in a triple store. This information is available as a SPARQL endpoint.
