Context-aware web services

I am starting an MSc thesis and I investigating in the field of context-aware mashups. Do you guys know if there are any standard which have already been set on the way the cont开发者_StackOverflow社区ext or point of interests are sent to the server? Like location, social information, language and other information about the mobile being sent in a particular format like a DOM or tree like structure or maybe xml.

Thank you.

Up to now there is no all around approach used for all service descriptions so usually there are no formal specifications for web services. But there are some general academic approaches to specify web services in web service repositories with the help of service specifications by using predicates and pre- post- conditions.

An good, but too complicated and failed approach: https://en.wikipedia.org/wiki/Universal_Description_Discovery_and_Integration
