DAWG-Architecture Update
The second meeting of the DAWG group focused on discussing important new technolgies (OAI-PMH, SCORM) and on developing and clarifying the needs of the network architecture. The diagram below illustrates some of the repositories interacting with a proposed RU repository.
High level view diagram
The architecture at this point is "content netutral." It should be able to capture any kind of data. Future policies may determine what actually gets "ingested."
- Repositories may have metadata that point to objects.
- Each has "communication channels", perhaps the OAI protocol for metadata sharing
- An academic department example (like "Physics"") might be a separate repository implementation.
- Z39.50 will be explored as an IRIS interface.
The RU Repository is to be: institution based capturing RU output and is intended to be cumulative and perpetutual while remaining open and interoperable with other systems.
The OAIS Functional model (an ISO standard) will inform our work to develop functional requirments.
The OAIS Functional model (with entities)
OAIS Reference Model [http://wwwclassic.ccsds.org/documents/pdf/CCSDS-650.0-B-1.pdf] (148 pp), is the model for designing the "RU Repository".
The timeline for DAWG-A's work is:
- January 2003 - Requirements/Architechture document
- February 2003 - Discussion, feedback with RUL and RU
- March - May 2003 - Evaulation of candidate stsyems (Dspace, Fedora et al.)
- June - August 2003 - Select system and prototype sample conmtent
- September - November 2003 - Prototype/trial integrated architecture (getting multiple nodes to interact)
Next scheduled DAWG-A meeting: December 11, 2 p.m., Heyer Room.
DAWG-Infrastructure Update
Mike:
- Timeline to be developed in next DAWG-I meeting
- Focused on task "Review, select, and propose a large mass storage system (> 10 TB)"
- Status
- Reviewed 3 products from EMC: Centera, Symetrix, Clarion.
- A couple of RU systems use EMC products (eg. RIAS) - Will review products by Adic in December 2002.
- Reviewed 3 products from EMC: Centera, Symetrix, Clarion.
- Will develop requirements after reviewing the field of solutions.
- Status
SCORM
Karen gave an overview of SCORM using printed PowerPoint slides from an earlier presenation.
OAI-PMH
Ron explained OAI-PMH (A Metadata Harvester protocol) using prepared printed PowerPoint slides.
