Hi,
FYI, here is the patent application's description:

Well, the LRA model as I read it seems to be a
relatively close mapping of sagas, which were as far as I know first
described in 1987 by Garcia-Molina. I think it would be useful if someone
took the action to provide a more detailed breakdown of what exactly is at
issue for the group, because it's not obvious to me after a cursory review
of the CheeTah papers.

Hi everyone,
The VLDB paper is attached. It describes composite
systems in the CheeTah prototype (which served as the provisional
application for the US patent).
Concerning WS-CAF, I think there may be some
overlapping with the LRA model described in the TXM spec.
It was not my intention to raise panic and 'warn'
anybody, rather just to point out that the patent exists (which is, I
believe, required on behalf of TC members).
Best,
Guy

Robin, thanks. I think a description from Guy about
how he thinks any patent
relevant to this paper may conflict with WS-CAF is in
order though. Many
companies have been doing composite
applications/transactions for years so
I'd like to know what aspect of CheeTah may either
impact WS-CAF now or in
the future. This is certainly the first I've heard of
CheeTah so from an
Arjuna perspective it certainly didn't influence
WS-CAF, but maybe Guy's
email is intended to just warn the TC in its future
directions?
Mark.

CheeTah: a Lightweight Transaction Server for

-------------------------------------------
Guy Pardon, Gustavo Alonso.

Abstract:
The ability to maintain transactional interaction
in a distributed system has proven to be a key
feature
in information systems. Unfortunately, as technology
moves
towards more distribution and decentralization, it
becomes
increasingly difficult to use existing transactional
tools. In fact, current solutions are entirely
unsuitable
for what we call composite systems. Composite systems
can be characterized as a collection of distributed,
autonomous components, linked in an arbitrary
configuration.
In this paper, we describe CheeTah, a Java based set
of
tools for building composite components capable of
interacting transactionally in arbitrary, dynamically
changing configurations. We describe the technology
provided,
how designers would use it to build composite
transactional
systems, and examine in detail the performance of the
resulting solution. Among the results we have
achieved,
the performance and the simplicity of use are of
particular
interest.

Guy,
To second Mark's email, can you please also send
additional information
about the patent, such as the VLDB paper you mention.
Thanks,

Hi all,
As a TC member it is my duty to report that there
exists a US patent (US
patent application 09/682,969 -- finally approved
about two months ago)
concerning composite systems and an additional
European application being in
process. This patent is probably relevant to the CAF
specs (and most likely
to BTP as well).
Basically, the patent is an extension of the
Composite Systems VLDB
paper we (Gustavo Alonso and I) had at VLDB2000.
Best,
Guy
