Soergel’s SemWeb Proposal

System of integrated access to data on concepts and terminology.

Bring together variety of sources that exist largely in separate worlds, including dictionaries, thesauri, classification schemes, etc.

Federated system with multiple collaborators.

Common interface to all concept & terminology knowledge bases on the Internet.

The Real Semantic Web

Namespace for uniquely identifying a semantic scheme & each concept within each scheme.

Broad template or conceptual schema for holding all types of semantic information & specifying relationships among them.

Definitions of services for interacting with the System.

Vocabulary Markup Language (Voc-ML)

XML schema for the Semantic Web.

Broad template for structured representation of semantic schemes. Dublin Core metadata.

Tags and syntax for uniquely identifying each concept.

Typed relationships (hierarchical, associative, etc.)

Typed notes.

Revision summary

Issues and Next steps

Voc-ML Version 1.7 Revisions

Added editDate and source attributes to all “customer” updatable elements.

Removed most remnants of Datafusion Concept Catalog, including CCID, XWalkHeader, etc.

Voc-ML Version 1.8 Revisions

Defined and commented Path ID syntax and usage. PID allows encoding of complex polyhierarchies with context-dependent children, e.g., MeSH. *

* This is still in flux. Currently all path information can be encoded in parent/child tags, but current Interwoven software will not read path tags.

Voc-ML Version 1.9 Revisions

Removed more excess elements from Datafusion Concept Catalog, including CCLoadFile, ForbiddenIDs.

Removed all instances of CTYPE attribute. (New ID reference semantics).

Changed optional Note & Misc elements to be allowed only once, not many times. *

* This is still in flux. Currently reflects what Interwoven software does, not what the standard should do.

Voc-ML Version 1.95 Revisions

Added editHistory and Edit elements in SVHeader.

Added editDate and Source attributes to Path element.

Edited and updated comments on Path, Parent, & Child to reflect new semantics of the ID reference attributes in these elements.

Added comments on commonHeaderBlock parameter entity to explain Dublin Core and cite DC reference.

Cleaned up many other comments for readability.

Voc-ML Version 1.99 Revisions

Added xmlns:dc attribute to root SrcVocab element.

Changed PID attribute in path to CDATA.

Changed UREF attribute in child to CDATA.

Made editHistory in the SVHeader optional.

Issues and Next steps

Voc-ML Issues

UID syntax (Light, 5/25/01)

Topic maps vs Voc-ML

Functions to be served by standards for machine-readable thesauri (Soergel, 11/21/01) Data input, transfer

Query and view

URIs

Normalization vs specialization (ASIS meeting, 11/13/01) Type all relationships (remove Parent, Child, RelatedTerm

elements)

Type all notes (remove Definition element, add type for Note)

Proposed Next Steps

Post Voc-ML 2.0

Provide examples of marked-up resources

Prepare W3C RFC
