Abstract

We design a schema language that includes channel schemas with capabilities of input, output, and input-output. These schemas may describe documents containing references to operations of remote services on the web. In this language, the subschema relation turns out to have an exponential cost. We therefore discuss a language restriction that admits a subschema relation with a polynomial cost.
