The Digital Collections Systems Sub-Committee (DCSSC)

Annual Report, FY04

Charge

The DCSSC is charged with advising OIS on the functionality and public interfaces of systems that manage and deliver locally stored digital library materials and other OIS infrastructure components without their own explicit oversight committees. The committee represents the interests of collection owners from across the university and reports to the Digital Acquisitions and Collections Committee (DACC).

Current systems under the committee's charge include:

  • Access Management Service (AMS), including the Policy Service
  • Digital Repository Service (DRS), including Web Admin and Asynchronous Delivery Service (ADS)
  • Full-Text Search Service (FTS) load and query services
  • Image Delivery Service (IDS), including the new JPEG 2000-based dynamic imaging
  • Name Resolution Service (NRS) administrative interface and resolution services
  • Page Delivery Service (PDS) delivery interface and maintenance system
  • Streaming Delivery Service (SDS)
  • Templated Database System (TED), including the Xorro XML schema-directed editing tool

Accomplishments in FY04

During FY04, the committee's work revolved around four main issue areas:

  • Functional requirements for the re-implementation of PDS and FTS

Full review of currently deployed PDS/FTS led to extensive enhancements proposed in function, behavior, and user interface. This is now anin process ULC-approved project.

  • Review of DRS preservation policy

An initial investigation of appropriate criteria for supporting new formats in DRS led to a review of the current published DRS preservation policy. This is now a topic under internal OIS discussion.

  • Review of the new dynamic image capabilities and user interface in IDS (aka large-image delivery service)
  • Collection/inventory management

The committee has identified a need to present curators and collection owners with a unified view of the materials in their collection independent of the multiple manifestations of those materials and independent of the specific systems in which those materials are managed.

Priorities for FY05

  • Monitor the progress and effectiveness of the PDS/FTS reimplementation
  • Represent the interests of curators/collection owners in discussions of the evolving DRS preservation policy
  • Refine use cases and functional requirements for a new collection/inventory management service
  • Review workflow processes regarding DRS deposit with an intent towards lowering the technical barriers to easy deposit
  • Continue oversight role for ADS, AMS, DRS, FTS, IDS, NRS, PDS, SDS, and TED
