The OCLC/NCSA Metadata Workshop Report
• “The Dublin Core is not intended to supplant other
resource descriptions, but rather to complement them.”
• The Dublin Core metadata elements describe essential
features of electronic documents (or “document-like
objects”) that support resource discovery…
• Dublin Core descriptors are intrinsic, extensible, syntax-
independent, optional, repeatable, and modifiable
1995

Some enduring ideas from Dublin Core…
Supports resource discovery. Fills a gap between indexing
and professional description. Is comprehensible across
domains and communities of practice.
Can be modified and extended.
Interoperable. Designed for reuse. Coexists with other
standards.
Dublin Core is a vehicle for contributing expertise from the
library community to the web (and vice versa).
