Not yet, no. Could you explain what you exactly mean by "build information"? There are 6 priority areas in the Web Hob analysis tool: build configuration, tasks, recipes, packages, image directory structure (if build target is a base image recipe) and time. When you say "build information", to which of these area(s) are you referring to? Once that's cleared, I can set to work in defining the data needed.

If you want to get a high level idea of what type of information is needed for each area, you can visit:

http://www.yoctoproject.org/webhob/phase3_final_web_prototype/project-build.html

And go through the pages in the left navigation.

Cheers

Belén

Thank you, Belen !

Recorded here, it this is part of our specification https://wiki.yoctoproject.org/wiki/WebHob_general_architecture

Do we have a similar definition for build information, that I am not aware of ?

Cheers,
Alex

I have managed to gather answers to most questions regarding task
information for Web Hob (thanks Paul, Alex and Richard for you help!).
I've updated bug 4275 with a new task information set

https://bugzilla.yoctoproject.org/attachment.cgi?id=1232

And a list of columns that will be available in the tasks table:

Any questions or comments, let me know.
