MICHAEL OAI repositories

MICHAEL publication modules expose data to external services using the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). These services are used by the MICHAEL European service to harvest contents from the national MICHAEL instances. The same services are also available to developers of other services using an OAI harvester.

Base Address

As specified in the OAI protocol, each MICHAEL repository has a base address from which the harvesters can collect data. The base address is built with the following parts:

• The root URL of the MICHAEL Platform (e.g. http://www.michael-culture.country/ )
• a fixed part to identify OAI services on the platform (sdx/oai/)
• the path of the search application application (usually pub-mpf or pub-country)
• the specific document base or type of records (may be one of dcollection, institution, service, pcollection, project).

For instance, the base address for the “digital collection” OAI repository for MICHAEL UK is: http://www.michael-culture.org.uk/mpf/sdx/oai/pub-uk/dcollection

Identify verb

To access the “Identify” verb, one would use the: http://www.michael-culture.org.uk/mpf/sdx/oai/pub-uk/dcollection?verb=Identify

Formats

All records in a MICHAEL OAI repository are available in the following formats.

• oai_dc Dublin Core. The schema URL is: http://www.openarchives.org/OAI/2.0/oai_dc.xsd
• oai_michael. This is the native MICHAEL record format. Terminology is coded. The schema URL is: http://www.michael-culture.org/namespaces/michael/oai/schemas/oai_michael.xsd
• oai_complete. This is the native MICHAEL record format. Terminology is de-coded (terms are available in various languages with their codes). The schema is extended to include additional information for related records. The schema URL is: http://www.michael-culture.org/namespaces/michael/oai/schemas/oai_complete.xsd
• oai_portal. This is the format used by the MICHAEL European service. It is the same as the complete format, except the terms are not expanded and are normalized to the MICHAEL Portal list terms. The schema URL is: http://www.michael-culture.org/namespaces/michael/oai/schemas/oai_portal.xsd
