How to set up templates that will inherit file properties from document sets

It makes a lot of sense to me! However I do not have SharePoint.

SharePoint has been reported in several forums having trouble using Word templates as templates. I am simply passing that on.

First, these are not truly "Document Properties"  but Content Controls mapped to XML parts that bear some resemblance/connection to traditional document properties. I am using the term "document properties" as parts that show up in vba under the built-in or custom document properties collections.

Greg Maxey wrote an application and explains quite a lot about the structure of these. Enhanced Document Properties AddIn  I attempted to explore them a while back and posted this discussion:  XML location of Document Properties in Quick Parts list - Expand / modify that list - Sharepoint.

Here is a video on mapping content controls in Word in general.

You could save such Content Controls as building blocks in the same template in a custom gallery and add a drop-down for that gallery to the QAT or a custom ribbon. They would need to be used in documents based on the template. I know that the mapped property would not work in a global template.

I experimented by creating a template with three mapped controls.

I saved them as building blocks in the Quick Parts gallery and when they are used in documents created from that template, they work as mapped controls.

Here is a temporary link to that template.

I added a button to the QAT in the template. If you were to save these in a custom gallery, you could put a button for just that gallery on the QAT.

I hope I've given you something to chew on and possible workarounds. I hope that someone with more SharePoint experience can point you to a simpler method.
