Introduction

Ontology Pattern Languages

An OPL for ISO Software Processes (ISP-OPL) The Language ISP-OPL Patterns

Applying ISP-OPL Requirement Process Ontology

Final Considerations

Motivation

Standards Harmonization Many standards and models

ISO/IEC 12207, ISO/IEC 29110, ISO 9001, CMMI, MPS.BR etc.

They are developed by different organizations or groups. They are not created under the same base of terms, concepts

and semantics.

When used in combination Interoperability problems.

Motivation

ISO Study Group Standards harmonization initiative Proposal: Ontological Framework

DEO: Definitional Elements Ontology

CDO: Configured Definitional Ontology

SDO: Standards Domain Ontology

Is there a good solution for ontology derivation?

Ontology Pattern Languages

Advantages expected of using OPLs for deriving compatible ontologies.

Modularity and Reuse

Productivity

Consistency

Interoperability (compatibility of the resulting models)

ISP-OPLISO-based Software Process OPL

Characteristics

Based on the Ontological Analysis of ISO/IEC 24744(in the light of UFO)

Reusing SP-OPL and E-OPL patterns

Purpose: to propose a sound solution for the derivation of ontologies in the ISO harmonization initiative.

ISP-OPLISO-based Software Process OPL

Scope Work Units

Regarding the composition of work units and its application contexts.

Human Resources Dealing with how people are organized in organizations and

teams, involved in projects, allocated to tasks, and perform work units.

Work Products Representing the nature and composition of work products and

how they are handled in work units.

ISP-OPL PatternsID Name Intent

Work UnitsWUD Work Unit Dependence Represents the dependences between work units.

WUC Work Unit Composition Establishes the composition of work units in terms of processes and tasks.

PPD Project Process Definition Defines the project of a defined process.WUS Work Unit Scheduling Defines the time boundary for work units.

PWUT Performed Work Unit Tracking

Register the tracking between performed and scheduled work units.

PWUD Performed Work Unit Dependence

Represents the dependences between performed work units.

PWUC Performed Work Unit Composition

Establishes the composition of work units in terms of performed processes and tasks.

PPP Project Process Performing

Defines the project of a performed process.

Final Considerations

Once understood, the OPL is easy to apply The major difficulties are on understanding the

standards and identifying the concepts and relations.

Enables a good productivity The development of the resulting ontology is faster

Leads to more consistent ontologies UFO ground, OPL built-in knowledge

Reaches interoperable ontologies Same OPL: compatible concepts
