Hi,
i am doing a project on semistructured databases right now. One thing that doesn't seem to be defined precisely is whether semistructured data is a graph or a tree. All the earlier papers (the lore project ones etc) state that it should be represented as a graph. But quite a lot of papers assume that the data model is a tree. Could anyone help me out.

Also is XML currently the most popular semistructured data format?
I've also heard of something called the RDF (Resource Description
Framework). does it have anything to do with semistructured data as
well?
Finally, has any work on parallel semistructured database systems been
done?
Thanks
Chaitanya
