The problem with XML (2)
- Different communities make different design choices for DTDs/XML Schemas
- all “good” (and valid)
- human reader of document can interpret (maybe)
- program needs prior “knowledge” of structural conventions in each XML schema
- Within resource description community, meaning(s) of structure(s) may be limited
- Across communities, potentially unlimited
- not scalable in an “open” environment
- how to manage ever increasing set of conventions
- always encountering unknown schemas
