More robust info

give the ability to view one particular property. show all attributes in the manifest. display in html by default or json if accept header is set
Thus far it hasn't been worth it to me to care about additional information being displayed that wasn't strictly needed.  That being said, I don't have an objection to these particular attributes being excluded, but I think we need to be careful not to be too judgemental.  It's better to include some information that isn't needed than accidentally omit information that is needed.
