• We propose to define and adopt a complete universal profiling schema for the content negotiation.

• The universal profiling must target different parameters of the heterogeneous environment:

Client: device description, user preferences
Services: documents and other services
Server capabilities: adaptation methods
Network: characteristics, etc.

The schema must be extensible and not limited to a particular kind of devices or architecture. Schemas must cover a wide range of description elements to allow developers to define their applications-related profiles
