Signpost (not a knowledge pack) for OMG modelling specifications — UML, SysML, BPMN, UAF, SoaML, MOF, OCL, XMI, DDS. Contains NO source content: it only points to where the official specs live and what each is for. Use when you need an OMG modelling/architecture specification — the OMG licence forbids redistributing or transforming the text, so these cannot be reconstituted into a pack; download them from OMG directly.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<!-- argument-hint: [spec name, e.g. SysML / BPMN] --> # OMG Specifications — Signpost (download pointers only) **This is a signpost, not a knowledge pack.** It carries **no OMG content** — no reproduced text, no synthesised summaries. The OMG Specification License permits only informational, unmodified, non-network-posted use, so OMG specs cannot be reconstituted into a redistributable knowledge pack (see this repo's `docs/SOURCE-VETTING.md`). What this skill does: tell you which spec you want and send you to OMG to get it. ## When to use You're modelling and reach for an OMG language/framework — UML, SysML, BPMN, UAF, etc. This points you at the authoritative source; read it from OMG, don't expect it summarised here. **Prerequisites:** none — plain Markdown. ## How to use Find your spec below, then download the current version from OMG. Every OMG spec lives at `https://www.omg.org/spec/<NAME>` (e.g. `/UML`, `/SysML`, `/BPMN`), which always links the latest formal version. Catalogue of all OMG specs: `https://www.omg.org/spec/`. ## The specs (what each is for — facts only) | Spec | What it is | Get it at | |------|-----------|-----------| …

How to install
mdr add jgsystemsconsulting/jgs-se-knowledge-packs/omg-signpost@sha256:cb76d7f50a9b28beThe line at the top of this page pins the label git:20260619.138f6d2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
