A theorem proving framework for the formal verification of Web Services Composition [PDF]

, 2011
We present a rigorous framework for the composition of Web Services within a higher order logic theorem prover. Our approach is based on the proofs-as-processes paradigm that enables inference rules of Classical Linear Logic (CLL) to be translated into ...
