10. BIBFRAME Approach
•
Identify functional descriptive requirements among various stakeholders
•
Balance the creative tensions between descriptive needs of past and
future
•
Recognize there is no “done”, but rather an evolving process
•
Define a high level Linked Data content / carrier model (simple things be
simple, complex things be possible)
•
Create Web Identifiers of “Nouns” and “Verbs”
•
Under specify the shared Schema
•
Provide a light weight means of constraining the option space to support
specific individual, community needs

11. !
BIBFRAME Profiles are a sharable
blueprint (from simple to complex) that
support a specific communities descriptive
need!
