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

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”

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
![Page 14: The Isaac Network](https://reader033.vdocument.in/reader033/viewer/2022051116/56814e1b550346895dbb81f5/html5/thumbnails/14.jpg)

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
![Page 16: The Isaac Network](https://reader033.vdocument.in/reader033/viewer/2022051116/56814e1b550346895dbb81f5/html5/thumbnails/16.jpg)
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
![Page 17: The Isaac Network](https://reader033.vdocument.in/reader033/viewer/2022051116/56814e1b550346895dbb81f5/html5/thumbnails/17.jpg)
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
