Paper Abstract:
|
Collaborative edition is achieved by distinct sites that work independently on (a copy of) a shared document. Conflicts
may arise during this process and must be solved by the collaborative editor. In pure Peer to Peer collaborative editing, no
centralization nor locks nor time-stamps are used which make conflict resolution difficult. We propose an algorithm
which relies on the notion or semantics dependence and avoids the need of any integration transformation to solve
conflicts. Furthermore, it doesn't use any history file recording operations performed since the beginning of the edition
process. We define editing operations for semi-structured documents i.e. XML-like trees, that are enriched with
informations derived for free from the editing process. Then we define the semantics dependence relation required by the
algorithm and we present preliminary results obtained by a prototype implementation. |
