 Mono-perspective business solutions
 Missing concepts for trustful inter-organizational collaboration
 ComVantage
 Collaboration infrastructure for virtual enterprises as add-on to
existing business solutions
 Secure semantic data harmonization and agile workflow
orchestration beyond organizational boundaries
Motivation & Objectives

“Initiating the transformation of isolated
individual companies towards an
integrated, agile virtual enterprise”

Decentralized Approach
6
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

 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
(Semantic) Data Modelling

 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)
SELECT ?order ?label
WHERE {
?order a <http://www.comvantage.eu/shop#Order>.
?order <http://www.comvantage.eu/shop#id> ?label.
}
Single Point of Access

 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)
Integration of Legacy Systems

 Collaboration can only be successful if partners can trust each
other
 Traditional XACML architectures  coarse-grained decisions
(repository level)  insufficient for industrial collaboration
 Need for multi-domain fine-grained access control for Linked
Data
Access Control
10
• Fine-grained policies  access to specific
sets of RDF data
• Secure and ad-hoc mobile distributed
collaboration

 Model-driven approach to create and execute workflows
across organizational boundaries
 Business process definition on multiple layers and model
types
 Navigation model as input
for application orchestration

Semi-automated selection of
generic app from pool
according to matching criteria
modeled in business process
Automated creation of orchestration
regarding the workflow model and
automated deployment as App
Ensemble to the target device
Manual adaptation of
generic app regarding
UI, data queries and
navigation design
