Hello, 

Galaxy workflow and history structure is stored in Galaxy's database vs. flat files so you can't just find the representation of those on the file system.

I actually don't know if there is any documentation about the JSON structure for those artifacts - I've CC'd the -dev mailing list so someone there might know (btw, emailing the -dev list is preferred with questions like these because your question get more exposure). In the mean time, you can explore the API documentation (available here and here) because that's where JSON objects can be retrieved.

Hope this helps,

Enis

I'm working on Galaxy.

I need to know about Galaxy syntax for worklfow internal structure description with JSON, and Galaxy workflow history.   

*if you have any technical document describing the JSON syntax used for the storage of Galaxy workflow and  Galaxy history, it will be very nice if you can send it to me.

*I installed Galaxy on ubuntu, In which directory can I find workflow histories files ?.   

Thank you for your considération, I look forward to hearing from you.
