“The Crete Meeting” -- Cooperation between Subject Gateways, held at EDLC, Crete, September 1998, organized by UK
“The View from the States”
The Isaac Network: One contribution to the “IMesh”
I. “The Crete Meeting”I. “The Crete Meeting”
Inspired by UK discussions of the future of “subject gateways,” e.g. coverage, sustainability
2nd Annual European Digital Library Conference: EDLC Informal meeting of 25 participants from 15 countries
DiscussionDiscussion
Common questions worldwide:
– Duplication and gaps in subject coverage
– Ongoing funding, self-sufficiency
– Interoperability and standards Need for guidelines for subject gateway development to
facilitate cooperation
Identified Common NeedsIdentified Common Needs
Summary of existing gateways “Best practice” guidelines Definition(s) of “quality resources” Scope of content Interoperability and standards
Result: Workshops Series for Result: Workshops Series for development of “IMesh Guidelines” development of “IMesh Guidelines”
Modeled on the success of the Dublin Core Workshop series
Invited group: 30-40 experts in related fields UK: Spring 1999 CEI/JISC funded USA: Fall 1999 NSF funded (proposed)

Working TogetherWorking Together
Educators and librarians will continue to use a wide variety of sources; special interest directories will play an important role
Organized and presented by those expert in the systemization of knowledge
Willingness to learn from success and failure of both ourselves and others
Cooperate, InteroperateCooperate, Interoperate
Cooperate to avoid duplication of effort on content Devise a division of responsibility Standardized content and quality guidelines Reasonably similar user interfaces Development of an “information architecture”
Metadata (!)Metadata (!)
Consistent metadata standards Metadata applied by neutral, expert third parties Mapping of different metadata schemas across collections Standardized indexing schemes
III. The Isaac Network: Resource III. The Isaac Network: Resource Discovery GoalsDiscovery Goals
Search highly selective collections of resources, hand-chosen by information specialists
A single query will reach geographically distributed collections
User doesn’t need knowledge of all collections Ultimately the end user is judge of what is relevant and
credible: we can narrow the subset
Content Development:Content Development:Top Down or Bottom Up?Top Down or Bottom Up?
Funding = Audience = Funding Local projects, funding based on local needs, local
audience Most chance for longevity: “projects” are becoming part of
operations Bonus: As content providers they want to share their work
more broadly
Needs of Content ProvidersNeeds of Content Providers
Content providers need to retain control Content, look and feel, maintenance of records Application of metadata Retain ownership and credit
Goals of the Isaac NetworkGoals of the Isaac Network
Build an infrastructure for sharing and searching metadata from distributed metadata collections
Test bed for experimentation with metadata, indexing, and query referral systems
Develop collaborative laboratory for future research: indexing algorithms, assisted robots
Potential Content PartnersPotential Content Partners
While primary audience is higher education, all are welcome and encouraged to join
Government, public libraries, non-profit, commercial May be focussed on a single discipline, or cover a broad
subject range Closed system maintains quality Can be a “full node” or a “collection node”
