- ----------------------------------------
-
-
- The preliminary agenda called for discussion on a wide range of topics
- related to the creation and implementation of Living Documents but in
- practice the majority of the discussion revolved around data
- representation issues for network-based information discovery and
- delivery systems.
-
- Much of the discussion centered upon the characteristics needed to
- implement a practical scheme for Universal Document Identifiers,
- contrasting these with a proposal for Unique Document Serial Numbers.
- UDIs have been proposed to allow multiple information systems to
- communicate location and access information. Initial proposals that had
- been circulated by Tim Berners-Lee, Brewster Kahle and others were
- discussed and these were compared to the information needed and currently
- provided by such systems as Prospero, W3, WAIS and others. No firm
- conclusions were reached, but it was agreed that a mailing list
- (nir@cc.mcgill.ca) would be created to pursue this issue with a goal of
- disussions about a possible standardization of UDIs for Internet use and,
- by extension, the purpose for which this BOF was initially called: Living
- Documents. Initially, all attendees of this BOF are to be placed on the
- list, and existence of the list is to be announced to the Internet
- community.
-
- Discussion concerning Unique Document Serial Numbers centered around the
- perceived need to identify and compare the _contents_ (in contrast to
- the location) of documents in an internet environment. Ideally, we would
- have a means for:
-
- a) Identifying the contents of a document
- and comparing it with other documents without
- copying and comparing them directly.
-
- b) Identifying derivative works and ancestral links
- between documents.
-
- c) Identifying documents that contain the same
- information despite representational changes
- that do not add or delete information contents.
-
- It was generally accepted that the first of these could probably be met
- with relatively straightforward signature schemes, but that the last two
- would be difficult or impossible using strictly syntactic means.
-
- The discussion continued across a range of topics, examining the other
- issues to be addressed in implementing Living Documents and
- network-based information systems. The following list was drawn up
- outlining some of the issues to be addressed in subsequent work:
-
- Univeral Document Identifiers:
- - design, documentation and deployment. Issues involved include
- the need to encode individual access methods and specific
- location information within a specified access method. An
- initial proposal for such a scheme had been circulated by Tim
- Berners-Lee prior to the meeting.
-
- Unique Document Serial Numbers:
- - design, documentation and deployment. Issues involved include
- identifying specific documents, version control and derivation
- information.
-
- Cataloguing Information:
- - Librarians already make use of far more cataloguing
- information than any of the experimental systems currently
- in use on the Internet. Work with those directly involved in
- library science working with extending MARC records, ISBN
- and ISSN numbers is called for.
-
- Discovery mechanisms:
- - There remains a large open problem in rapidly and
- efficiently discovering the existance and location
- of information in a large distributed computing environment.
- The proposed UDIs and UDSNs may enable such systems to be built
- but additional work is still needed. There are problems both
- in locating individual service providers and specific pieces
- of information.
-
- Authentication and Access Control:
- - Security issues were not discussed in depth, but it was agreed
- that such issues would become more important as large-scale
- systems are developed and deployed.
-
-
- Editorial Control:
- - Again a topic touched upon only briefly, it was suggested by
- one participant that true Living Document systems would have
- to include some method of imposing editorial control.
