MOM and SOA on Linux?
dogmeant asks: "I have yet to see MOM (message oriented middleware) offerings on Linux much less open source projects that address the same. And while we're at it, what about tools that address SOA/BPM (Service oriented architecture/business process modeling) type architectures on Linux? Is the Open Source community ready to take on challenges like this?" If anyone else out there has this particular itch, maybe this will be another niche in which Open Source software can catch some Enterprise mindshare.
The IBM middleware family, formerly known as MQSeries, now called IBM WebSphere MQ family, has ports for Linux. More info on the IBM site
Vinci is a SOA for Linux. The site describes it as "a local area service-oriented architecture designed for rapid development and management of robust web applications"
I have attended presentations on MQ series, and found it interesting, but never had any opportunity to use it. I found the Vinci paper by googling.
Jabber is normally thought of as yet another IM system, but "Jabber is an open XML protocol for the real-time exchange of messages and presence between any two points on the Internet" (from the Jabber site). Its first application has been IM, but it is by no means limited to IM. Jabber is a protocol specification, and there are several open and closed source implementations of clients and servers.
xmlBlaster is a more traditional MOM offering, under LGPL. It supports numerous protocols and bindings into a number of languages.
As usual, Google offers a lot of advice on the topic of 'mom middleware "open source"', including a list of MOM implementations which tells us that JORAM is also open source, and an article entitle Open Source in Middleware.
