[glue-wg] flat xml rendering

[Warren Smith]

My general opinion is not to have any -ies elements (e.g. ComputingActivities) to group elements. To me, this grouping of elements (e.g. ComputingActivity) isn't needed in XML. It doesn't seem to make it any easier to process the XML using SAX or DOM. It seems easy to find all -y elements in a document without a -ies element as a parent for visualizing. Similarly, it also seems easy to find -y elements in an XML document if you want to translate it to LDAP or SQL or whatever.

I haven't really done much xPath... Can someone explain how grouping elements would help? It seems like either way you'd include 'ComputingActivity' in the expression. That is the expression would start with "/Entities/ComputingActivities/ComputingActivity..." or "/Entities/ComputingActivity...".

Bear in mind that in the production Grid there are about 4000 endpoints, so grouping may not help a lot with visualisation unless you do it more finely.
