  • Introduce myself Thank you for the invite Comment on Michelle and Jeanne’s presentations Overview: -Briefly review history of EAD development -Give an appraisal of the current state of EAD -Review likely changes -Offer some half baked ideas of possible changes
  • -International Standard for Archival Description (General) -Encoded Archival Description 1.0 -ISAD (G) revised -EAD 2002 -eliminated some unnecessary layers of encoding, -brought EAD up to compliance with ISAD (G)’s second edition -EAD 2002 schema – Replicated the existing tag set in W3C and Relax NG schema languages. -Enforced proper use of ISO country codes, date normalization patterns. -Introduced namespaces to EAD in a limited way -Namespace for EAD and xlink
  • -International Standard for Archival Authority Records (Corporate Bodies, Persons, and Families) -Encoded Archival Context (Corporate Bodies, Persons, and Families) -Who submitted comments on the draft CPF schema? -International Standard for Describing Functions -EAC-Functions -International Standard for Describing Institutions with Archival Holdings EAC-IAH [Mention EAG]
  • Collection Management Systems ICA-AtoM open source web app
  • Current state of affairs: EAD widespread and successful. It has proven that there is a need for archival data transmission standards and inspired work on related standards such as EAC-CPF. EAD is extremely flexible, and can accommodate a broad range of descriptive practices and traditions.
  • EAD’s flexibility - it’s initial selling point - has ultimately gotten us stuck. [discussion of difficulty to implement in CMS context] It also shows its age - doesn’t play well with others. Bit of a loner. Goals for a revison: -Simplify -Play nicely with others What are some likely changes?
  • [Add unit attribute to <extent>/<dimentions>, first check in tag library.] -Dimensions -Better way to handle this in VRA core? Not sure, need to investigate
  • [Add unit attribute to <extent>/<dimentions>, first check in tag library.] -Dimensions -Better way to handle this in VRA core? Not sure, need to investigate
  • -EAD Working Group being re-charged as part of Standards Committee re-missioning. -Will become Technical Subcommittee for Encoded Archival Description -Call for volunteers will go out soon, if you area at all interested, please throw your name in the hat. -Once the new group is charged, hopefully at the Winter SAA Council meeting, revision will get under way in earnest. -Call for comments may go out earlier. -Please contribute! -Hope to complete the comment period by SAA annual meeting in DC., get started then.
