A Formalization of the SMEPP Model in Maude

Workflow-based semantics for peer-to-peer specifications

“…Such semantics formally establishes whether a set of SMEPP processes (viz., peer or service code) can be executed together without locking, and is currently exploited to develop a prototype MAUDE-based analyser [7]. As we already mentioned, we have also developed a prototype implementation of the SMEPP middleware that includes a tool for the transformation of SMoL descriptions into Java code [5].…”

“…The groupDescription parameter specifies the name of the group and information related to the security level of the group (viz., in the form of access credentials) that sets the visibility and the access to the group (e.g., see 3 7 The question marks denote optional parameters, square brackets represent arrays and angle brackets composite data structures getGroups and join). GetGroups returns an array of group identifiers based on an input group description (e. g., groups having a particular name and/or credentials).…”

“…3) Convert the SMoL specification into the corresponding higher-level aSMoL specification and perform a global analysis of the set of all aSMoL specifications available by exploiting the Maude verifier [7]. 4) Convert the SMoL specification into executable code (by means of automatic translators like SMoL2Java [5]), to be further tested via simulations in a SMEPP environment of peers and services.…”

“…The semantics of aSMoL formally establishes whether a set of peer and service specifications can interoperate correctly without locks. Such a formal semantics has been implemented in a proof-ofconcept verification tool based on Maude [7]. The introduction of aSMoL (as sketched in Fig.…”

Twenty years of rewriting logic

“…giving formal semantics to various object-oriented design notations, architectural notations, and software modeling languages, e.g., [33,40,42,[60][61][62]65,66,110,154,169,197,268,269,[345][346][347]363,393,394,474], and 2. giving formal semantics to various middleware and distributed coordination mechanisms, e.g., [13,14,153,167,168,350,402].…”
