A model is proposed for the representation of context by means of open logic theories parameterized by metavariables covered by constraints. The model is formalized and implemented using constraint logic and metalogic programming notions. Accommodation, understood as the process of extracting presuppositions embedded in a discourse or, in general, extracting the contents embedded in a stream of observations, fits naturally into this model as abduction. A possible worlds' semantics is given similar to a proposal given by Stalnaker.
