Example of a scientific

workflow that implement
a proteomic experiment
The analysis operations
that compose the
workflow are provided in
this case by third party
web services.

4. BENEFITS OF RESEARCH OBJECTS
11 February 2012
Aresearch object aggregates all elements that
are necessary to understand research

investigations.
Methods (experiments) are viewed as first class
citizens
Promote reuse
Enable the verification of reproducibility of the
results

11. GROUNDING WORKFLOW-CENTRIC RESEARCH
OBJECTS USING SEMANTIC TECHNOLOGIES
11 February 2012
Workflow-centric research objects are encoded using RDF,
according to a set of ontologies that are publicly available
Research objects use the Object Exchange and Reuse (ORE)
model, to represent aggregation.

We use the Annotation Ontology (AO), to annotate research
object resources and their relationships.

16. CONCLUSIONS
11 February 2012
ResearchObjects capture information that is
necessary for understanding the results of
research investigations as well as the methods
DICoSE workshop
(workflows) used in those investigation
Wepresented a model for specifying workflow
research objects
Wespecified how instances of that model can be
encoded using semantic web technologies using
standards such as Object Exchange and Reuse,
and the Annotation Ontology

17. ONGOING AND FUTURE WORK
11 February 2012
We
are currently developing in the context of the
Wf4Ever project a family of tools for the
management of workflow research objects
DICoSE workshop
Integration with the myExperiment Social Network
Portal
We are also investigating issues such as:
Decay
Discovery and Reuse
Scalability
