Kernel Metadata at a Glance
Kernel Semantics: four required elements
who - a responsible person or party
what - a name or other human-oriented identifier
when - a date important in the object's lifecycle
where - a location or system-oriented identifier
ERC Syntax: Electronic Resource Citation
erc: who: Lederberg, Joshua what: Studies of Human Families for Genetic Linkage when: 1974 where: http://profiles.nlm.nih.gov/BB/AA/TT/tt.pdf

Working Group Status
ERC/Kernel WG Charter (October 2002):
to explore the ultra-simple ERC "kernel" approach to metadata
to identify applications of the compact ERC record format
to refine ERC value rules and minimum element requirements
to develop an XML representation of kernel elements
50 subscribers to the mailing list (October 2004)
New 6-point work plan (August 2004): much progress to report
Second face-to-face meeting

Documentation efforts
Draft Kernel Metadata Specification, now available at
//www.voudr.com/groups/kernel/spec.html
Creating an XML mapping to/from the ERC format
No progress to date
Critical for interoperation, exchange, import/export
Looking for volunteers for writing and/or editing

Kernel Working Group Recommended Next Steps
XML mapping continues to be a priority.
Documentation needs work, and should emphasize outreach.
How about ERCs for relationships and events? For example, describe a dissertation (a document) and link to its defense (an event).
Feedback suggests it may make sense to separate requirements; think about separately pursuing (a) required kernel elements, (b) ERC syntax, (c) null values for missing elements (which could use better indexing guidelines).
Question about maximizing and minimizing at the same time: how to reconcile the drives simultaneously to define a minimal record and to extend a vocabulary with additional elements?
