OAI-PMH and IUCr Publications

The Open Archives Initiative (OAI, www.openarchives.org) was set up to develop and promote a framework for facilitating the efficient dissemination of digital content, for example between publishers and libraries/digital archives.

The OAI-PMH (Protocol for Metadata Harvesting) sets out the technical standards to be used in order to allow harvesting (collection) of metadata.

The IUCr fully supports the OAI-PMH; technical details of our service are given below.

OAI-PMH service

The IUCr OAI-PMH service is one method of obtaining article metadata for IUCr publications in oai_dc - Dublin Core format.

OAI-PMH Base URL:

The IUCr OAI-PMH base URL is http://scripts.iucr.org/cgi-bin/oai/.

OAI-PMH setSpecs:

In addition to general OAI queries the IUCr OAI-PMH service provides 11 "set" filters, these are as follows:
