For some information filtering experiments I'm looking for XML data sources that are:
- suitable for keyword search, as RSS/Atom feeds,
as weather forecast or auction reports but also texts
- updated often, as RSS feeds are, so it make sense to filter them
- but not RSS feeds, because I need something:
- where not only schema element values can be changed
but also new schema elements (XML tags) can be introduced
to bring new semantics to the data
Do you know any example of such data?
The application will filter such data without knowing schema in advance, using keyword queries.
