Suggest: Workbookinfo, Sheetidentifier and publishing state

[came]

Hi Tableau Team,

I think that dashboard extension is an awesome concept with many valuable use-cases to come for Tableau customers (we are already using the Tableau JS API). Looking a little bit into the API I am wondering that a few (I think) essential information are missing (compared to the JS API) when using tableau.extension.*

Especially I haven't found any reference to the containing workbook of the dashboard? There are no unique identifiers for the sheet (dashboard) as well as worksheet? Besides it would be valuable to know if the workbook has already been published or not. In summary:

• no workbook references (not even the name?)
• no uniq. identifier of the dashboard (or included sheets) e.g. sheetUrl or viewIds?
• is workbook published / unpublished

Is that because of technical limitations or just because of early phase? Would be great if you share your view on that.

BR, Carsten
