2. Topics for today
• Cataloging from a linked data perspective
• Describing vs. identifying
• Mapping vs. linking
• Interlude: Technical basis for linked data
• Library Linked Data: 2 Examples
• Dewey.info
• WorldCat.org + schema.org
• Why should librarians care?

3. Define “metadata”
Implications for descriptive
cataloging “Metadata is data associated with
objects which relieves their potential
- produces surrogates users of having to have full advance
knowledge of their existence or
- transforms textual characteristics.”

17. Strings as keys
Identification by description
• Heading construction based on elimination of ambiguities
• Parts are added to increase specificity of description to avoid conflicts
with other headings
• Use of abbreviations, punctuation, special delimiters
• Form of heading carries meaning (dates, etc.)
• Headings relate to other headings
• Keys act as access points for records, not described entities
≈ cutting a key based on a vague
description of a lock that may not even exist
