I'm having some difficulty adding a web service to my hub. I've copied the url and input the required fields but it seems like the "Tag*" is not being accepted. I've tried creating a new tag and making sure that the entry matched existing tags but neither seems to work. Please advise:
I think that you just need to press Enter on your keyboard once you've typed the tag, or word. The ArcGIS Hub Metadata Tags will accept the asterisk "*" (see below); however, I can't think of many cases when this would be necessary.
