| description | 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. |
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 |
|---|
| UML | Unified Modeling Language — general-purpose software/systems modelling | omg.org/spec/UML |
| SysML | Systems Modeling Language — systems engineering (a UML profile; v1.x) | omg.org/spec/SysML |
| SysML v2 / KerML | Next-generation SysML and its kernel language | omg.org/spec/SysML (v2 listings) |
| BPMN | Business Process Model and Notation — process modelling | omg.org/spec/BPMN |
| UAF | Unified Architecture Framework — enterprise/defence architecture | omg.org/spec/UAF |
| SoaML | Service oriented architecture Modeling Language | omg.org/spec/SoaML |
| MOF | Meta Object Facility — metamodelling foundation | omg.org/spec/MOF |
| OCL | Object Constraint Language — constraints on models | omg.org/spec/OCL |
| XMI | XML Metadata Interchange — model serialisation/exchange | omg.org/spec/XMI |
| DDS | Data Distribution Service — real-time pub/sub data | omg.org/spec/DDS |
Why not a real pack?
The OMG public grant says the spec "will not be copied or posted on any network computer …
and no modifications are made." A hosted, transformed pack would breach both, so the whole
OMG formal/ corpus is on this repo's Excluded list. This signpost stays clean by holding
only spec names, purposes, and the OMG URL — facts and a citation, never the source text.
