Decentralized Approach

Execution of agile and interorganizational workflows on application layer

Collaboration partners run their own infrastructure within encapsulated domains

Semantic data harmonization within the domain and beyond by using mappings

Data source stay under full local control of owner and are lifted to semantic data on demand

m Each partner provides an ontology of his local data model Ontologies of new partners can reuse parts of existing partners

and add missing concepts (ontology extension approach) Conflicting definitions between partners are resolved via model

mappings Each partner defines local access control policies to keep full

control about shared and protected data A set of common roles is defined throuhgout the collaboration

network

m Applications are completely decoupled from individual data soures Application connect to static endpoints for each domain to

retrieve data from different partners SPARQL is used as uniform interface on top of a uniform data

format (RDF and Linked Data design principles)

m Legacy system are integrated on demand by using adapters Linked Data adapters perform a mapping from syntactic data to

RDF Mapping is done at design-time but data extraction is done at

run-time and on-demand (no redundant semantic data needs to be synchronized)

ComVantage provides generic adapters that can be configured to be used on top of a concrete data source (configuration is done with the local ontology of the domain)

Traditional XACML architectures coarse-grained decisions (repository level) insufficient for industrial collaboration
