Deliverable D6.2 Toolchain required by guidelines for system portal

Abstract

This deliverable provides a description of the tools that support the manipulation with semantic

information within the SPIKE platform. The formalisms and tools for ontology development are

proposed for particular steps of the requirement-driven approach. The WSMO Studio is selected

as a general toolkit for business processes modelling and for semantic annotation of process

elements –tasks, services, and information artefacts. The identified toolkit will be employed to

produce the ontologies and business process models for the SPIKE application cases in the first

trial of the pilot applications.

 

This deliverable describes a suite of tools that are proposed as a semantic framework within

the SPIKE platform. The proposal of tools is based on the methodology published in [D6.1]

for creation of semantic knowledge base and its usage for semantic annotation and mark-up of

business processes and information resources. In particular, the steps of the requirementdriven

approach towards the ontology development [KliUk07] are taken as functionality

constraints for selection of formalisms and tools that will support the semantic knowledge

base creation and maintenance. Various formalisms such as structured texts, tables, taxonomy

of categories, and ontology-like structure are proposed for the steps 1-5 of this approach, i.e.

to capture the requirements and information needs of the users within the scope of the SPIKE

application cases.

The WSMO platform [WSMO] was identified already in [D2.1] as an appropriate solution for

representing the semantically enriched data within the SPIKE platform. In addition to the

WSML ontology language and powerful WSMX execution environment, it provides the

WSMO Studio toolkit [WSMOStudio], which enables quite easy and user-friendly

implementation and maintenance of the resource ontology structure. This toolkit is proposed

for steps 6-8 of the requirement-driven approach, i.e. for the implementation, semantic

enhancement, validation, and administration of the resource ontologies.

Moreover, the WSMO Studio provides in its latest version the BPMO modeller tool

[Dimitrov07], which enables visual creation of business process models. Integration with the

resource ontologies and Web services in a single environment enables easy and transparent

annotation of the tasks, sub-processes, and artefacts in a process model by the semantic

ontology elements (i.e. goals, mediators, axioms, concepts and instances).

This deliverable presents a process of selecting a suitable toolkit for the SPIKE semantic

framework. Envisioned functionality, defined according to the methodology proposed in

[D6.1], usability, and technical compatibility with the other components of the SPIKE

platform are used as criteria to evaluate the candidate tools for the ontology design,

development, business process modelling, and semantic annotation. The WSMO Studio is

consequently proposed as the most suitable toolkit.

In addition to the selection of tools, this deliverable provides quite a detailed description of

features and functions of the selected toolkit, as well as some usage instructions that are

specified from the users’perspective. It should help the user partners to employ the WSMO

Studio toolkit in the next phases of the project to construct the semantic knowledge bases and

process models that will adequately represent the semantic characteristics of the respective

application cases. The results of this effort, i.e. the resource ontologies and semantic models,

will be published in the forthcoming deliverable D6.3.
