The Semantic Web (SW) efforts produced a suite of standards and technologies that provide some syntactic and semantic formats for data distributed over the World Wide Web (Web). Its ultimate goal is to provide a way to integrate and combine heterogeneous information sources that are geographically spreaded, evolving without a master control and under different ownerships.

Considering that metabolic and regulatory pathways related data have been published in different formats, we believe that the use of SW technologies may address the integration challenge that is behind those types of data.  We have implemented models of regulatory and metabolic pathways using an RDF framework, a SW data model describing Web resources that provide merge mechanisms for data integration. In order to accomplish that we extended the IsaViz software, an RDF public authoring tool. Examples of metabolic and regulatory networks were implemented to show the library use and how the models are built. Refer to the Models section for more details.
