Yes, I think I can explain what I meant. Thanks for asking.
I have been using TabId on my own sites as the unit from which to orient navigation and content. A TabId refers to a page, but if the page is moved the TabId stays the same.
Pages are sort of the unit from which a website is created. In DNN the TabId is the ID of the page. This may all sound obvious and redundant, but I have found that using the page or TabId as a container works for a wide variety of content.
So in my roundabout way I am saying yes, a TabId from which a link to a page could be formed. Then you could put a map on that page. But you could also put many other things on that page, such as a redirect to a new window, a ticket purchase form, gallery from last times event, video etc.
I have a site with events. Events happen at locations and on my site each location has a page. But if I put my page url in the map url of the Event Location it get's lost as soon as I get Friendly Names working right.
