DLF Registries

A key role of the DLF is to facilitate information sharing amongst its members. In support of this, the DLF Office of the Director maintains registry services that record information about members' digital collections, their digital library activities, and their documented expertise.

Services are maintained on the basis of information supplied by members in their Newsletter reports.

Available registries include:

Digital collections

A web-searchable database of members' publicly-accessible, online, digital collections.

Documenting the digital library

A web-searchable database of policies, strategies, working papers, standards and other application guidelines, and technical documentation developed by DLF members to inform or reflect upon their digital library development activities.

Both registry databases are now harvestable using the OAI metadata harvesting protocol. To see harvestable records:

1. Go to http://oai.dlib.vt.edu/cgi-bin/Explorer/oai2.0/testoai
2. Select "University of Michigan Library, Digital Library Production Service" from the scroll list
3. Select "List Sets"
4. Scroll to the bottom of the list.
5. Select Digital Library Federation (DLF) Catalog
6. You retrieve a hypertext list of the metadata record identifiers

An OAI service provider would use the link from the top of the page, e.g., http://www.hti.umich.edu/cgi/b/broker20/broker20?verb=ListIdentifiers&metadataPrefix=oai_dc&set=oaiall;Adlfbib, to run a harvester to gather IDs for these records, or http://www.hti.umich.edu/cgi/b/broker20/broker20?verb=ListRecords&metadataPrefix=oai_dc&set=oaiall;Adlfbib to harvest the records themselves. .
