Computer science description: We present a type-based analysis for role-based multiparty interaction. Novel to our approach are the notions that a role specified in a protocol may be carried out by several parties, and that one party may assume di%erent roles at di%erent stages of the protocol. We build on Conversation Types by adding roles to protocol specifications. Systems are modeled in ⇤-calculus extended with labeled communication and role annotations. The main result shows that well-typed systems follow the role-based protocols prescribed by the types, addressing systems where roles have dynamic distributed implementations. date: 2011-09 type: Conference or Workshop Item type: PeerReviewed format: application/pdf language: en identifier: http://eprints.imtlucca.it/2317/1/Inforum11_TorresVieira.pdf identifier: Baltazar, Pedro and Vasconcelos, Vasco Thudichum and Torres Vieira, Hugo Typing dynamic roles in multiparty interaction.
