Metadata Guidelines
NTL - Dublin Core Metadata Guidelines
The NTL catalog is a metadata repository for information about the digital objects preserved in the digital repository and about the websites selected for inclusion. The Catalog uses a modified Dublin Core metadata schema. Current refinements are defined to support the use by the transportation community. The current NTL Catalog Metadata Guidelines are available for review and use by other transportation resource providers. This standard follows the Dublin Core Metadata Library Application Profile.
