We present a semantic B2B gateway based on the WSMX se- mantic Service-Oriented Architecture to tackle heterogeneities in RosettaNet messages. We develop a rich RosettaNet ontology and use the axiomatised knowledge and ...

Developers of Semantic Web applications face a challenge with respect to the decentralised publication model: where to find statements about encountered resources. The ¿linked data¿ approach, which mandates that resource ...
