Dear,

  I'd like to write a designer for the UIPAB. According to some information I've found on the web, a DSL and a recipe are appropriate to develop an UIPAB designer. Accoring to others, I should use GAT.
  There are four walkthroughs for DSL and a book about software factories. Where do I find such information for GAT ? It seems that there is "only" one sample (TechEd2005Hol) for GAT and no "abstract overview" of the GAT functionality. Is the "Guidance Automation Toolkit Help" the only option to get a 10 000 feet overview of GAT ?

Kind regards,
Bart

The GAT help gives you quite a closer view than 10000 feet ;). You should definitely start from there.

With regards to designers, yes, you should do them with the DSL SDK.
