From: Gerhard Pfau [mailto:GPF...@de.ibm.com] Sent: Wednesday, January 21, 2009 05:09 To: bpel...@lists.oasis-open.org Subject: [bpel4people] NEW ISSUE: Supporting batch operations

Dear all,

as just discussed pls. find below the summary of the new proposed issue we have
just talked about:

TARGET: WS-HumanTask

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.
.

Best regards,

Gerhard
