A distributed approach to XML interoperability

We expand upon previous research performed on creating a lightweight infrastructure for the purpose of achieving interoperability among XML data sources. The approach is based on enriching local sources with semantic declarations so as to enable interoperability. These declarations capture the information content and concepts of the sources through mappings to a common application specific vocabulary. We design and implement a peer-to-peer network architecture through which global queries are initiated and responded to. We further examine and implement a methodology for merging the XML results of global queries into a single XML formatted response.
