SALUS Semantic Middleware
SALUS Advisory Board Meeting - January 17, 2013
Semantic Interoperability Formalization of more then ‘just’ terminology, but also the relations between
concepts and the context Constraining the semantics = limiting possible interpretations People can interpret according to the context, computers don’t
This summer I travelled to Java
This software module is written in Java
My preferred brand of coffee is Java
IntroductionThe Semantic Interoperability Platform (SIP)
A simple thing (?) Put a semantic layer on top if any resource Define a common ontology (or a system to mediate
between ontologies) Query data as if everything behaves as one virtual

At development (deployment) time: creating "formal library"At any time: formalizing upfront (triple cache)
At runtime: formalizing (via querying) and deducing (via reasoning with rules)Using formalisms declared in ontologies
