The Flemish Department of Economy, Science and Innovation (EWI) has started
the Flanders Research Information Space programme (FRIS) in 2007 with the goal of
transparent and automated flowing of research information via the construction of an
information architecture. Doing so, the FRIS programme wants to accelerate the inno-
vation value chain by (i) efficient and fast access to research information for all relevant
stakeholders; (ii) offer improved customer services (e-government); and (iii) increase
efficiency and effectiveness of the R&D policy. For FRIS to become sustainable, EWI
has set the following critical requirements.
– Data provenance and goverance Data must be collected at the point of creation,
i.e. in the operational processes of data providers (e.g., universities, funding bodies,
etc.). For example, information on a research project can be found in the assessment
process for a funding application. Collecting information at the operational process
level offers major advantages. The data are accurate and up-to-date because they
are being used in an operational process. Also, it is not necessary to establish a
parallel data gathering process, so data providers are spared a lot of administrative
work.
– Scalability FRIS, initially targeted at the Flemish region, is intended to be scaled
out to a European context. The increase the potential of design and maintenance
scalability, a service-oriented paradigm is chosen for the FRIS architecture.
– Reusability The FRIS service components must be maximally reusable. Therefore,
the use of business semantics standards to describe data and services is required.
E.g., as a member of EuroCRIS3 , EWI is participating in the further development
and maintenance of the Common European Research Information Format standard
(CERIF) standard. CERIF emerged from early pre-FP research projects including
EXIRPTS and IDEAS. Today, substantial improvements have been implemented
with the model, concerning in particular the introduction of a so-called Business
Semantics Layer4 that makes the model flexible and scalable for application in
very heterogeneous environments. Moreover, EuroCRIS wants to push forward this
standard as OMG standard by using OMG SBVR5 .
– Long Tail Variability Broadly, each nation state has a similar research process of:
strategic planning; programme announcement; call for proposals; proposal evalua-
tion and awarding; project result monitoring, project result exploitation. However,

for each of these “commoditized” processes, every stakeholder has different ex-
pectations of the underlying services. Two processes may involve many repeatable
activities. However, the effective implementation of a process to produce one par-
ticular service usually involves many variations of control flows and stakeholders.
Moreover, different regional backgrounds of the respective stakeholders add up to
the complexity. Hence, the mere static meaning (read: data semantics) of research
data is not sufficient anymore. In order to provide a more complete (i.e. less am-
biguous) interpretation of the data, data semantics has to be complemented by the
“dynamic” semantics of the particular service context in which data was created or
manipulated.
A combination of service development and a managed change process will achieve
the strategic goals6 . Artifact-Centric Service Interoperation (ACSI)7 is a new research
and development initiative funded by the EC that roots its business semantics-driven
framework on two fundamental constructs, namely, interoperation hub and business
artifact.
An interoperation hub serves as a virtual rendezvous for multiple services that are to
work together towards a common goal. Domain-specific interoperation hubs such as the
EasyChair conference submission management system or Salesforce.com have already
shown the value of interoperation hubs; the research here will make it possible to easily
create, launch, participate in, and maintain ACSI interoperation hubs in essentially any
application domain. Similar to EasyChair, an ACSI interoperation hub will serve as
the anchor for a collaboration environment, that is, an IT environment used to support
large numbers of service collaborations that operate independently, but which focus on
essentially equivalent common goals. Unlike orchestrators, an interoperation hub works
well in the context of open service networks. These hubs are primarily reactive, serving
as a kind of structured white board that participating services can refer to, that can be
updated with information relevant to the group, that can assist the services by carrying
out selected tasks, and that can notify services of key events.
The interoperation hubs used here will be structured around dynamic artifacts. These
provide an holistic marriage of data and process, both treated as first-class citizens, as
the basic building block for modeling, specifying, and implementing services and busi-
ness processes. In the context of single enterprises, it has shown that the use of artifacts
can lead to substantial cost savings in the design and deployment of business operations
and processes, and can dramatically improve communication between stakeholders, es-
pecially in cases where they represent different “silos” of the enterprise or community.
Artifacts can give an end-to-end view of how key conceptual business entities evolve as
they move through the business operations, in many cases across two or more silos. As
a result, artifacts can substantially simplify the management of “hand-off of data and
processing between services and organizations. A key pillar of the ACSI research is to
generalize the advantages of artifacts to the context of interoperation hubs and service
collaborations.

A first realisation is the FRIS research portal (http://www.researchportal.be) to exhibit current
research information on projects, researchers and organisations of the Flemish universities.
