Operation transforms for a distributed shared spreadsheet
Christopher R. Palmer, Gordon V. Cormack · 1998
The Distributed Operation Dansform (dOPT), pr~ posed by Efi and Gibbs, is used to dfie concurrently updatable shared objects.Eh and Gibbs give the OP eration tr~orrus that d&e a simple shared text editor supporting single chmacter insertions and deletions on a hear btim.We report here on the construction of operation transforms for a more sophisticated group nwe appficatiou a shared spreadsheet.We identify a set of abstract operations that &aracterize the operations on a spreadsheet.Using Cormack's Cdtius for Concurrent Update, which extends and corrects dOPT, m'egive the tr~forms on these operations necessary to d~e a shared spreadsheet.~re use the transforms to btid a shared version of SC, the Unix spreadsheet due to Goshg.
