Semantic Web Web Services
Purpose of this Document
This page was constructed in answer to a query for resources on Semantic Web web services. Its descriptions are highly subjective and will maintained it as long as it excites me.
Resources
- Semantic Web Working Symposium (SWWS)
- Stanford University, July 30, 2001 - gathering of a couple hundred SW geeks had a track on "(Web-)Services and Applications" with some practical implementations of service discovery and recombination. Proceedings are in PDF - no HTML version available.
- DAML-S: A Semantic Markup Language For Web Services
- Describes DAML-S 0.5. Describes relationship to UDDI, WSDL, E-speak and ebXML.
- Serching for services on the semantic web using process ontologies
- Use MIT Process Handbook schema to store service description ontologies. Specialized BD query interface called Process Query Language.
- Approach to Service Description for Matchmaking and Negotiation of Services
- Advantages/disadvantages of using RDF for web service advertisement. Flower vender example. Insufficient discussion of DAML capabilities. No proposals.
- The Briefing Associate: A Role for COTS applications in the Semantic Web
- From the abstrace: Use COTS to help generate ontological descriptions of the content of manually produced documents. Tool to import DAML ontologies into Powerpoint slides.
- ITTALKS: A Case Study in the Semantic Web and DAML
- Use DAML to express ITTALKS (an IT lecture service) subject, time and location. Has fallbacks 'cause users don't actually have DAML-enabled agents yet.
- Open Learning Repositories and Metadata Modeling
- SQL-backed tripple store (different from McBride's), PHP web front end. OLR API speciallized accessors to propert values (eg. getResourceTitle). Comparison to O-Telos Modeling Language.
- DAML-S
- This web services ontology using RDF and the Darpa Agent Markup Language provides a well thought-out and practical way to descibe web services so they can be precisely discovered.
- Supercharging WSDL with RDF
- Uche Ogbuji's article describing how WSDL could be encoded in RDF. This approach differs significantly from DAML-S. I perfer DAMl-S but beleive this provides a good path for WSDL folks to see how easily their data may be made available to the semantic web.
- Annotated RDF WSDL Examples
- An annotated version of an example from Uche Ogbuji's paper that is intended to make it easier to understand the schema.
- WSDL RDF Mapping
- An attempted to translate the intended WSDL model into an RDF model.
Terms
- advertisement
- Communicating a service description to a party interested in using that service or to some third party which the party will query.
- description
- A set of parameters that characterize a web service so that someone looking for such a service will be able to identify it.
- discovery
- The process by which an interested party locates a service fitting some criteria.
