The document discusses updates to the STEP architecture. It provides an overview of the STEP standards and their use across the product lifecycle. The update aims to make STEP more model-based and sustainable for the long term by supporting multiple implementation technologies and integration with other standards like SysML. Achievements so far include a proof of concept for AP242. The roadmap outlines continuing work to integrate tools and fully realize the new architecture over several versions. Contributions from experts in areas like SysML and model-driven engineering are welcomed.
