This coordination is typically organized through orchestration (requiring a central coordinating entity) or through choreographies. While the latter approach allows for a fully distributed coordination, the need also arises for a distributed conformance check, ensuring that each participant of the choreography behaves according to the general choreography. <\/jats:p><jats:p> In this paper, a formalism is presented to ensure this conformance at design time, with possible extensions to deploy time and to runtime conformance checking. This formalism is referred to as the piX-model and it will be shown that the approach taken is inherently less complex, both in time and space, than the conventional \u03c0-calculus-based approach, whilst offering the same conformance guarantees. This gain in performance allows for a small design turnaround time, and also opens the avenue to runtime conformance checking by resource constrained devices. <\/jats:p>","DOI":"10.1142\/s0218843010002097","type":"journal-article","created":{"date-parts":[[2010,6,17]],"date-time":"2010-06-17T11:17:33Z","timestamp":1276773453000},"page":"1-30","source":"Crossref","is-referenced-by-count":1,"title":["WEB SERVICE CHOREOGRAPHY CONFORMANCE VERIFICATION THROUGH THE piX-MODEL"],"prefix":"10.1142","volume":"19","author":[{"given":"GREGORY","family":"VAN SEGHBROECK","sequence":"first","affiliation":[{"name":"Department of Information Technology (INTEC), Ghent University \u2013 IBBT, Gaston Crommenlaan 8 bus 201, B-9050 Ghent, Belgium"}]},{"given":"BRUNO","family":"VOLCKAERT","sequence":"additional","affiliation":[{"name":"Department of Information Technology (INTEC), Ghent University \u2013 IBBT, Gaston Crommenlaan 8 bus 201, B-9050 Ghent, Belgium"}]},{"given":"FILIP","family":"DE TURCK","sequence":"additional","affiliation":[{"name":"Department of Information Technology (INTEC), Ghent University \u2013 IBBT, Gaston Crommenlaan 8 bus 201, B-9050 Ghent, Belgium"}]},{"given":"BART","family":"DHOEDT","sequence":"additional","affiliation":[{"name":"Department of Information Technology (INTEC), Ghent University \u2013 IBBT, Gaston Crommenlaan 8 bus 201, B-9050 Ghent, Belgium"}]},{"given":"PIET","family":"DEMEESTER","sequence":"additional","affiliation":[{"name":"Department of Information Technology (INTEC), Ghent University \u2013 IBBT, Gaston Crommenlaan 8 bus 201, B-9050 Ghent, Belgium"}]}],"member":"219","published-online":{"date-parts":[[2012,4,6]]},"reference":[{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1016\/0890-5401(92)90008-4"},{"key":"rf3","volume-title":"The \u03c0-Calculus: A Theory of Mobile Processes","author":"Sangiorgi D.","year":"2003"},{"key":"rf6","volume-title":"The Spin Model Checker: Primer and Reference Manual","author":"Holzmann G.
