Properties of schema mashups: dynamicity, semantic, mixins, hyperschemas
RefleX and Active Tags were present at Balisage: The Markup Conference in August 2008 (Montréal, Canada).
The W3C XML Schema 1.1 is in a "last call working draft" status. One of the most significant change is perhaps the support of co-occurrence constraints that was missing in 1.0 and expected by the community. For the other missing stuffs -who knows what they are- we have to wait for W3C XML Schema 1.2 and so on. In this paper, we'll have a prospective approach: we examine some features that the author has already implemented as a demonstration, and imagine others that lead us to consider new usages of schema technologies.
For this purpose, we introduce an experimental but innovative schema technology : the, or ASL. The strength of ASL comes from its runtime environment : the engine that was presented last year at Extreme Markup Languages in Montreal. can host several runnable tag libraries and a schema language like ASL is just another library like other tag libraries, but built on top of this framework that offers to ASL lots of valuable services.
