ITGumbo: spicing IT up

We have observed the requirement and utility of the normative metadata definition by standards organization for common vocabulary in the semantic web application open market. Also the new context and synonyms of a 'thing' can be added as property and sub-property of a subject. A web service provider can avoid metadata mapping by including metadata terms from normative vocabulary for public interface.

Meza-Aleman & et al. have discussed that it may be impossible to enforce the use of a single common vocabulary in the wider web community. I would want to argue this statement by suggesting that delay in propagating the requirement and utility of a common vocabulary will make it difficult and probably impossible; in the absence of normative metadata many RDF vocabularies may come-up which may have to be reworked at a later time. Mills Davis has predicted the development of semantic web to continue from now until fourth decade of this century. As more and more applications are being developed there is not only a requirement but necessity for normative metadata. Meza-Aleman & et al. have proposed ExpertFinder initiative to find existing vocabularies, to extend the established vocabularies and reuse vocabularies. They have illustrated a requirement of mapping metadata from one vocabulary to another through a conversion function by application of SPARQL & RIF rules. In my opinion, too many vocabularies will limit the information access scope as more conversion rules will be required for newer vocabulary support. It will be comparatively easier to build a thesaurus based context mediator. If conversion rules are to be built in the web service application this may require web service enhancement every time it interfaces with a new web service application, keeping context and semantics out of a web service will make development easier and faster leaving metadata mapping and rule resolution to context mediator (semantic broker or service intermediary). The context mediator may find new web services with a different rule set by automated service discovery or subscription service. This will allow the new web service to integrate with any number of web services supported by the context mediator without any integration overhead. The awareness about existence of normative metadata as other semantic technology standards is a task to be assimilated.

The fourth European Semantic Web Conference was held June 3-7th, 2007, in Innsbruck, Austria. In ESWC participants were encouraged to use ESWC published metadata for all published information, this enabled use of semantic tools for intelligent search. The objective was to build semantic database and demonstrate the application of semantic technologies to the attendees in order to convince them about the abilities of semantic technology. This metadata is published as an official semantic conference metadata that is also being used by ISWC.
