First, you are free to leave the tool unpopulated, with no ill effects.
Second, the tool provides a "configuration point" for setting site-wide
policies about the metadata associated with content in general; it
also allows specialization of these policies based on the content type.
The "editable" elements of the Dublin Core (at present, Title, Description,
Subject, Format, Language, Rights) each have a "default" policy, plus
zero or more content-type-specific policies. Each policy specifies:
- Whether the element is "required"
- Whether to supply a default value when a new content object
is created, and if so, that value (currently, only allows
"literal" values for the defaults).
- Whether to enforce a "vocabulary" for the element (i.e., must
its values be drawn from a controlled set of values).
- The "vocabulary" (which may be "suggested values" if the
"enforce" flag is not set).
So, for instance, you could require that Title, Description, and
Subject be supplied (your skins and/or workflow would need to use
the tool to validate this), and supply default values for Language
('en-US', or 'es-ES', or whatever) and Rights ('Copyright (c) 2001,
MyCompany, Ltd.; all rights reserved').
I've created a how-to with this information, and a more detailed
recipe for implementing these policies, at:
