CA 2258704

A Shared Document Framework for use by an application program (1410) provides collaborative access to a shared document (1490) by means of a caucus service (1460) associated with the shared document (1490). The caucus service (1460) receives messages from caucus members (1430, 1441, 1480) and broadcast transmits them to all caucus members (1430, 1441, 1480) in global order. The Framework includes shared document class information (710), from which a shared document instance may be created. The shared document class information includes means for creating a local copy of the document being shared (1410, 1440); means for causing the application program to join the caucus service as a member (JOIN); means for receiving a command binding from the application program and sending it to the caucus service as a message (1432, 1442); and means, responsive to a command binding broadcast by the caucus, for applying the received command binding to the document when the application program did not send the command binding and for applying the original command binding when the application program did send the command binding (1431, 1443).

L'invention concerne un structure pour documents communs, destinée à être utilisée par un programme d'application (1410) et qui donne l'accès commun à un document commun (1490) au moyen d'un groupe (1460) associé au document commun (1490). Ledit groupe (1460) reçoit les messages provenant du groupe (1430, 1441, 1480) et les radiodiffusent à tous les membres du groupe (1430, 1441, 1480) dans l'ordre global. Ladite structure comporte des informations (710) sur la classe du document commun à partir desquelles un exemple de document commun peut être créé. Lesdites informations comportent des moyens pour créer une copie locale du document mis en commun (1410, 1440); des moyens permettant au programme d'application de rejoindre le groupe en tant que membre (JOIN); des moyens pour recevoir une confirmation de commande en provenance du programme d'application et pour l'envoyer au groupe sous forme de message (1432, 1442); et un moyen, répondant à la diffusion d'une confirmation de commande du groupe, pour appliquer la confirmation de commande reçue au document lorsque le programme d'application n'a pas reçu la confirmation de commande et pour appliquer la confirmation de commande d'origine lorsque le programme d'application n'a pas envoyé de confirmation de commande (1431, 1443).
