A framework for thinking about mechanisms

1
A framework for thinking about mechanisms

• Range of possible implementation mechanisms
• Some criteria for assessing various mechanisms
• Holding tank description
• Applying criteria for assessment to the holding
  tank (2 slides)

2
Possible Mechanisms for Improving Quality by
Resource Lifecycle

• More focused selection criteria from filter to
  guidelines
• Co-development of collections with user
  communities
• Development of thematic collections
  responsibility, ownership, persistence
• Pre-cataloging review of gray cases
• Encapsulation of context at design times wrap
  questionable in content guiding use
• QA of resources in Broad Collection
• Review board for marginal cases
• Holding Tank
• Annotation services / Peer reviewing
• De-accessioning request form

3
Some Criteria for Assessing Mechanisms (in random
order)

• Technical implementation
• Social implementation
• Community Participation opportunities for versus
  required to be successful
• Cataloging and QA Cost
• Maintenance Cost
• Scalability
• Preserving annotations during harvesting
• Proactively supports collection development
• Helps to create a collection that follows the
  selection criteria

Holding Tank Description

• Post-cataloging
• Provisional accessioning (30 days)
• Whats new area
• Available, but flagged, in discovery
• No comments automatic ingestion
• Comments someone has to review and pass a
  verdict

5
Applying Criteria to Holding Tank

• Technical Implementation
• Basic technical substrate is being implemented to
  support whats new in CRS
• Social Implementation
• Issues with asking collections (including NSDL-
  funded collections) to internalize DLESE
  rejections to support reharvesting
• How are holding tank reviewers mobilized to
  respond to new resources
• Registration
• Commenting
• How are comments assessed and by whom?

6
Applying Criteria to Holding Tank (part 2)

• Full cataloging and QA efforts invested in
  resources that are ultimately rejected
• Maintenance cost for 30 day holding period (e.g.
  applying link checking)
• Scalability O(n) depends on applying to all
  collections vs. community collection
• Provisional items unavailable for harvesting
• No explicit support for building collections
• Depends on the successful implementation of the
  mechanisms
