urdad.org and docs.urdad.org are open

URDAD now has a public home. urdad.org says what the method and its tool suite offer, and docs.urdad.org holds their documentation. Everything published there is openly licensed, under CC BY 4.0.

Learn the method

The URDAD method introduces the method without presupposing any tool: its principles, the steps it repeats at every level of granularity, and two models worked through from their use cases to the processes that realise them. The cheat sheet puts the notation on two pages, every symbol drawn as the modelling tool draws it.

Look something up

• The user manual, for how the tool behaves, from modelling to deploying an instance.
• The model specification: every element of a URDAD model, generated from the model’s JSON schema, which is itself published at its identifier.
• The specifications of URDAD-OCL and URDAD-FEEL, the two notations a model’s conditions are written in: their grammar, meaning and standard library.
• The glossary, with every term at an address of its own.
