Research for Development (R4D) Gateway
所有者:
R4D is a free access on-line database containing information about research programmes supported by DFID. R4D provides you with the latest information about research funded by DFID, including news, case studies and details of current and past research in over 30,000 project and document records.
… The R4D Gateway data provider service allows access to metadata about documents and outputs that are available in the R4D research portal repository. The service implements the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) using either Dublin Core or RDF formats.
Special instructions for getting data from this service:
This dataset is available through different services (see specific instructions under the relevant distribution):
1) A SPARQL endpoint at http://linked-development.org/sparql;
2) An OAI-PMH target at http://r4d.dfid.gov.uk/Gateway/;
3) A Linked Data API with base URL http://linked-development.org/.
4) A data dump at http://linked-development.org/data/r4d/dump.
