FiatFlux-P - User-Level Workflow Design: A Bioinformatics Perspective - page 110

5.3.1 Domain Model
As for any PROPHETS workflow scenarios, also the domain model for
FiatFlux-P comprises service and type taxonomies, service descriptions and
domain constraints. They are described in the following.
Taxonomi e s
Figure 5.8 shows the service taxonomy of the FiatFlux-P domain model. The
taxonomy defines the service categories DataInput , DataOutput , FiatFlux and
Helpers ,ofwhich FiatFlux defines the additional subclasses Preprocessing ,
MetabolicFluxAnalysis and MetaforAnalysis in order to distinguish between
the different analysis steps. As the figure shows, the concrete services (avail-
able as SIBs) are then sorted into the taxonomy tree, that is, the different file
reading services are classified as data input services, the file writing service
is classified as data output service, the different FiatFlux services are linked
to the corresponding sub-categories, and the special service for iterating over
multiple CDF data sets is classified as a helper service.
