“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
