Discovery level metadata catalogue for datasets published in the [Norwegian Polar Data Centre](https://data.npolar.no), published on the web in the [Dataset API](http://api.npolar.no/dataset/?q=). The catalogue contains Arctic and Antarctic research datasets originating from the Norwegian Polar Institute and its partners. Metadata is available in a number of formats and may be harvested using [OAI-PMH](http://www.openarchives.org/pmh/), see below for details. Metadata is also available in human readable form in the [Norwegian Polar Data Centre](https://data.npolar.no/dataset), as well as shared internationally in the NASA's [Global Change Master Directory](http://gcmd.nasa.gov/). #### Dataset search API The [Dataset search](//api.npolar.no/dataset/?q=) API provides powerful search with multiple response formats: * JSON * GeoJSON * DCAT/JSON-LD * CSV Example queries * [Datasets with a distribution](http://api.npolar.no/dataset/?q=&filter-links.rel=data) HTML * [List of marine dataset](http://api.npolar.no/dataset/?q=&filter-topics=marine&fields=link.edit,title&format=csv) CSV * [Antarctic datasets (latitude -90 to -45)](https://api.npolar.no/dataset/?q=&filter-coverage.north=-90..-45) JSON * [Newest first](http://api.npolar.no/dataset/?q=&sort=-created) #### Dataset REST API The Dataset REST API supports the multiple response formats and 2 edit formats (JSON and DIF) Examples * [JSON](http://api.npolar.no/dataset/a89b2682-e1f8-44b5-ab73-e6ba65f3a7a7) * [DIF XML](http://api.npolar.no/dataset/a89b2682-e1f8-44b5-ab73-e6ba65f3a7a7.xml) * [ISO 19139 XML](http://api.npolar.no/dataset/a89b2682-e1f8-44b5-ab73-e6ba65f3a7a7.iso) * [Atom](https://api.npolar.no/dataset/a89b2682-e1f8-44b5-ab73-e6ba65f3a7a7.atom) Prior to storage documents are validated against the [Dataset JSON schema](https://api.npolar.no/schema/dataset) and against the [DIF XML schema](http://gcmd.nasa.gov/Aboutus/xml/dif/dif.xsd). #### OAI-PMH provider The [OAI-PMH provider](http://api.npolar.no/dataset/oai?verb=Identify) supports all 6 verbs from the [v2 spec](http://www.openarchives.org/OAI/openarchivesprotocol.html#ProtocolMessages) * [Identify](http://api.npolar.no/dataset/oai?verb=Identify) * [ListIdentifiers](http://api.npolar.no/dataset/oai?verb=ListIdentifiers) * [ListMetadataFormats](http://api.npolar.no/dataset/oai?verb=ListMetadataFormats) * [ListSets](http://api.npolar.no/dataset/oai?verb=ListSets) * [GetRecord](http://api.npolar.no/dataset/oai?verb=GetRecord&metadataPrefix=dif&identifier=0323b588-5023-57d1-bf98-201cd8192730) 0323b588-5023-57d1-bf98-201cd8192730 * [ListRecords](http://api.npolar.no/dataset/oai?verb=ListRecords&metadataPrefix=dif) **DIF** **Advanced** Selective harvesting (sets and time range) * http://api.npolar.no/dataset/oai?verb=ListIdentifiers&set=marine&metadataPrefix=dif * http://api.npolar.no/dataset/oai?verb=ListIdentifiers&from=2013-11-01&until=2013-11-15&metadataPrefix=dif * http://api.npolar.no/dataset/oai?verb=ListIdentifiers&from=2013-11-01&until=2099-01-01&metadataPrefix=dif&set=cryoclim.net
