Joining forces
Together with BEA, IBM and Microsoft jointly drafted the Business Process Execution Language for Web Services (BPEL4WS) and two correlative specifications, Web Services Coordination (WS-Coordination) and Web Services Transaction (WS-Transaction).
The sheer number of variously complementary and conflicting specifications that have cropped up in the past six months indicate "a great deal of interest within the industry in addressing this problem area," the W3C's new working group said in its charter.
The onslaught of proposed standards reflects not only the complexity of integrating different business processes with Web services, but also the strategic nature of the proposed standards.
Third-party software companies that would eventually build software based on any standards would be reluctant to pay royalties on an ongoing basis.
And some industry executives have speculated that standardising business process integration risks making the technology a commodity, which threatens the established business of the larger information technology providers.
Where there's interest in Web services, conflict is not far behind. The intellectual property issue roiled the standards world for much of last year as companies with sizable patent portfolios tried to get the W3C to introduce an exception for RAND technologies to the consortium's policy of only implementing standards that are royalty-free.
RAND stands for "reasonable and non-discriminatory". But opponents of the RAND exception, who ultimately prevailed at the W3C, argue that with companies like IBM--last year's patent champion--negotiating within the same group as small firms, no exception to the royalty-free policy truly can be reasonable or nondiscriminatory.
With the formation of the choreography working group--which W3C members said was considerably delayed thanks to political skirmishes--the intellectual property issue is once again front and centre.
"BPEL4WS has an (intellectual property) statement that, as it stands, makes it questionable as to whether it could be used as a foundation piece," said W3C representative Janet Daly. "Given that all three authors come from the W3C membership, and they're all participants in the Web services activity, we're looking forward to them making a decision that's in their interest."
By that, the W3C means a decision to drop intellectual property claims on the specification--which analysts don't necessarily expect the BPEL4WS co-authors to do.
"I think the W3C should be careful, because the OASIS group could make the claim that the whole notion of Web services flow and choreography is in their purview," said Ron Schmelzer, a senior analyst at ZapThink, a research firm that focuses on XML (Extensible Markup Language) and Web services.
Noting that OASIS has a number of key Web services specifications under its purview already, he added that the "W3C sometimes assumes that they have the position of control, and that's not always the case."
Microsoft said it has not decided whether to join the W3C's new working group or what its position will be on the issue of intellectual property and BPEL4WS. IBM could not be reached for comment.
