Subject: [bpel4people] NEW ISSUE: Supporting batch operations
as just discussed pls. find below the summary of the new proposed issue we have just talked about:
DESCRIPTION: Task list clients often deal with many human tasks, performing the same action on them at the same time, e.g., when a user operates on a selection of several tasks in a UI application. Today in WS-HT this is accomplished by invoking a particular operation for each single human task of such list. When dealing with larger numbers of human tasks this involves a lot of communication between client and server and thus should be optimized. For example instead of a claim operation that takes a single task id as an input we may want to offer a batch claim operation that processes a set of task ids in a single operation.
PROPOSAL / THOUGHTS: Analyse the operations in chapter "6.1 Operations for Client Applications", and particularly "6.1.1 Participant Operations", and define which operations are likely to be called for a set of human tasks and deserve optimization by offering a corresponding batch operation. Specify these batch operations (input / output / fault messages). Agree on a naming scheme for batch operations that makes clear which original operation the are derived from. .
