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.

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.
![Page 9: Vocabulary Markup Language (Voc-ML) Project](https://reader035.vdocuments.us/reader035/viewer/2022062519/56815037550346895dbe358b/html5/thumbnails/9.jpg)
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.

Cleaned up many other comments for readability.

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
