How is NSDL different from a mere repository or a specialized "Google®"?
1. Interoperability: NSDL is not a library but a fundamental element in the transformation of educational infrastructure to the post bibliographic world. Interoperability will be the key to sustainability, and interoperability will be guaranteed by:
a. Shared metadata specified by Dublin Core Metadata Initiative
b. NSDL Metadata Resources Page:
http://metamanagement.comm.nsdlib.org/IntroPage.html
c. Collection Building NSDL: Form for submitting collection metadata:
http://metamanagement.comm.nsdlib.org/collection_forum.html
d. NSDL XML schema: currently in use by the NSDL Metadata Repository
http://ns.nsdl.org/schemas/nsdl_dc/nsdl_dc_v1.00.xsd
e. Open Archives Initiative: OAI Metadata Harvesting Protocol is preferred method for metadata harvesting:
