2025-03-25 Metamodel Discussed at OMG TC Meeting in Reston VA
In Q1, the team of CASCaDE work-package 1 has prepared a draft metamodel for a knowledge graph containing interrelated product information from different sources. A major design goal is to reduce the graph’s power of expression as much as permitted by the real world data, so that the choice of technologies is as wide as possible. Requirements have been identified to assess potential solutions. A simple example has been prepared for illustration and review.
The discussions last week in Reston with other OMG initiatives such as SysML v2, RAS, SPDX and others have shown a lot of potential for cooperation and reuse. For good reason, users expect complementary standards.
Please have a look:
- Product Information Graph Metamodel (draft): Online with Relations and transformed to HTML.
- Very Simple Model with Requirements: Online with Relations and transformed to RDF according to the metamodel.
As a next step, an ontology shall be developed to map the concepts of different domains to the integrated graph and the metamodel shall be verified and validated with real world data. Towards this end we urgently need help by companies developing and offering mechatronic products (the ‘users’) and interested software vendors: CASCaDE is for you!

2024-12-13 OMG approves RFP
We are pleased to announce that the CASCaDE Request for Proposal (RFP) has been approved by the OMG Architecture Board (AB) and Technical Committee (TC). This is a major milestone on the way to standardize the collaboration in the product lifecycle from end to end. A controlled vocabulary and a common context for so far partial product data are in focus.
Major ideas behind the RFP are explained here and the RFP itself ist published on the OMG website.
Members of prostep ivip and GfSE have prepared the RFP document in the past months.
As a next step, a submission team for a standard will be formed. The associations GfSE, prostep ivip and VDA have agreed to sponsor the effort. The team is looking for further funding to accurately verify and validate the concepts to be submitted.
