I am trying to create several master lists at the top level of a SharePoint Online site - master calendar, master contacts, etc.

I want to be able to display these lists on Subsites, but I'm running into an error. I've used SharePoint Designer 2013 to create a data view web part which I then save to the site gallery. But when I try to add the new web part on a subsite, I receive the following error:

"The file you imported is not valid. Verify that the file is a Web Part description file (*.webpart or *.dwp) and that it contains well-formed XML."

What am I missing? I would very much appreciate any ideas! Thanks!
