Subject: RE: [ws-caf] Patent Issue(s)


On the surface, it does not seem to confict since it requires a specific implementation of Java classes and operations that create the transaction system, whereas the WS-CAF approach is to wrap or abstract the transaction systems (i.e. not to create one).

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

Plug-and-Play Internet Data Management


-------------------------------------------

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,


Eric

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
