OAI support for PoliticalMashup/War in Parliament collections

We support the OAI Protocol for Metadata Harvesting (OAI-PMH) for harvesting of our data collections. The OAI-PMH endpoint lives at oai.politicalmashup.nl; it allows access to the metadata of our Dutch parliamentary proceedings, members of parliament and political parties databases. All our identifiers live in the oai:urn:nbn:nl:ui:35 namespace.

The OAI-PMH endpoint supports the verb GetRecord, Identify, ListRecords and ListSets. The only metadata format supported is DIDL, the MPEG-21 Digital Item Declaration Language.

We support the optional Sets feature of OAI-PMH. The available sets are listed by the ListSets verb; the relevant ones are currently

For example, to obtain a list of all political parties, do a ListRecords with the set p:nl. To get more information about the first item listed, urn:nbn:nl:ui:35-nl.p.aov, do a GetRecord on it: http://oai.politicalmashup.nl/?verb=GetRecord&identifier=oai:urn:nbn:nl:ui:35-nl.p.aov.

Among the returned information from a GetRecord operation is a resolver URL that can be used to fetch the full record. In the nl.p.aov example, that URL is http://resolver.politicalmashup.nl/nl.p.aov
