The term metadata means “data about data.” Authors,
librarians, and information scientists use metadata to classify content for organization
and retrieval.
The Getty Research Institute publishes a valuable general introduction
to metadata, Introduction to Metadata available
at http://www.getty.edu/research/institute/standards/intrometadata/index.html.
DSpace currently uses a qualified version of the Dublin Core
schema based on the Dublin Core Libraries Working Group Application
Profile (LAP). DSpace uses the LAP as a starting point for its
application of Dublin Core, borrowing most of the qualifiers from
it and adapting others to fit. Some qualifiers were also added to
suit DSpace needs.
DSpace and OAI
DSpace supports the Open Archives Initiative’s Protocol for
Metadata Harvesting (OAI-PMH) v2.0 as a data provider. OAI support
was implemented using OCLC’s OAICat open-source software to make DSpace
item records available for harvesting. DSpace at MIT is registered as a
data provider with the Open Archives Initiative. Other institutions
running DSpace may choose to turn on OAI or not, and to register as
a data provider or not.
