Discussion Items: Summary Only

Paul gave some opening remarks. He explained the need for all the security which we had encountered; a great deal of the laboratory's work is for the military.

OVERVIEW OF ARCHIVING ACTIVITIES SINCE THIRD US WORKSHOP

Don provided an overview (Item 1) of what has been happening since the last meeting. His presentation covered three points:
1. Breakout of functions with a "Process Box (Item 2) which Randy had developed
2. Version 4 of draft Reference Model which was the version discussed at the International Workshop (IWS). He itemized the numerous comments from those discussions (Item 3).
3. International workshop itself (Item 4) at which there was broad international participation
He reviewed the results of the French National Data workshop
He reviewed Claude Huc's paper "Toward a metadata model" (Item 5), indicating he felt it is an interesting paper. He also felt more of the metadata perspective should be included in the Reference Model.

DATA ARCHIVE REFERENCE MODEL VERSION 5

Both Lou and Don reviewed in detail (with extended discussion) the current version 5 which basically included most of the comments from the International Workshop's sessions on Data Archives. (Items 1 and 6)

COMMISSION ON PRESERVATION AND ACCESS

The final report from their Task Force on Archiving Digital Information (Item 8) was discussed.
It was decided that we need to write a letter to the Commission on Preservation and Access (not to the Task Force).
Bob will draft a letter which is to introduce our activity to the Commission, show cognizance of their activity and indicate how our efforts are different but complementary

PLANS FOR DATA ARCHIVE REFERENCE MODEL VERSION 6

Following extended discussions in several areas (as can be provided), the following conclusions were resolved:
