I'm not finding what I'm looking for in the API for the arcpy.mp class. I would like to access the metadata properties of a map inside my Pro project in a python script. I'm guessing the answer is "no, you cannot" since its not in the documentation, but I thought I'd put it out there just in case.
I am using a map to create a draft service and it would be nice to pull out the metadata information of the map (Summary, Description, tags, etc) and incorporate them into the SD file. I would have thought that information would be passed along automatically, but it doesn't seem to be.
Just had a look at the API and I too cannot find a way to drill down to that information in ArcGIS Pro 1.4. I would say that information is currently unavailable in that version of ArcGIS Pro. Suggest you add that to the ideas website as an improvement.
