Interdisciplinary collaboration across the product lifecycle is becoming increasingly important. One of the key topics is data-driven collaboration in engineering – an area addressed by several project groups within the prostep ivip association. To enable these groups to work more closely together and jointly tackle cross-cutting topics, a consistent approach to knowledge and information management is essential. For this reason, the Technical Steering Committee launched the Psi Ontology (psiOnt) initiative.
The goal of psiOnt is to create a cross-project-group information model that identifies commonalities and interdependencies as well as gaps between individual project groups, and makes the resulting insights actionable. The use of a Top-Level Ontology (TLO) is intended to increase efficiency across project groups. In addition, the insights gained through this initiative on the use of web technologies and ontologies are designed to provide association members with valuable guidance for addressing the challenges of information interconnectivity.
The documentation, provision, and accessibility of ontologies have been standardized across prostep ivip. Accordingly, information and ontologies from VEC, CDT, and the Top-Level Ontology are now available via the association's GitHub repository. The DDP ontology is currently undergoing the OMG standardization process as part of the CASCaDE project. As an additional domain model, the VEC ontology has been assessed for its relevance to the top-level and its coverage by TLO elements.
The initiative faces the ongoing challenge of aligning the semantics of ontologies from various project groups and integrating them into a shared overarching ontology. A particular challenge is obtaining feedback from the practical application of these ontologies in order to continuously refine and further develop the models.
The next step is to pilot the TLO in line with the CDT vision, in conjunction with a Core Ontology and domain ontologies. Insights gained will feed back into further development. As in previous years, regular exchange and collaboration with all interested prostep ivip project groups will continue.
"Collaboration between the project partners and the involved project groups has worked very well. Supporting the adoption and use of ontologies remains an ongoing priority."
"The ontology landscape within the association has evolved significantly in recent years. The TLO is an integral part of this landscape – which is why we will continue to seek close collaboration with the project groups in the coming year."
