I'm not sure I understand the question correctly. Yes, it is possible to carry information in the url. Try for example to click the upload image on the right side of http://en.wikipedia.org/wiki/Wikipedia:WikiProject_India/Wiki_Loves_Monument... . That could give for example: http://commons.wikimedia.org/w/index.php?title=Special:UploadWizard&camp... which carries the identifier, the description, latitude and longitude.
Yup. See [1] & [2] for more documentation
