Interoperability of contentInteroperability of content

• I-MASS deals with diverse content throughout I-MASS deals with diverse content throughout various heterogeneous systemsvarious heterogeneous systems

• This content is to be provided uniform from a This content is to be provided uniform from a user’s point of view, this is done in three steps:user’s point of view, this is done in three steps:– From data source to RDFFrom data source to RDF– From local standard to global schemaFrom local standard to global schema– Towards full semantic interoperabilityTowards full semantic interoperability
