Adobe has acquired Day Software, a company which specialises in web content management. Its products include the CRX Java Content Repository and the CQ5 Web Content Management Platform. One of its distinctive features is an emphasis on interaction and collaboration. Day’s chief scientist is Roy Fielding, co-founder of the Apache Software Foundation and well-known for his work on REST (Representational State Transfer).

The acquisition gives Adobe a stronger presence in the open source community, and it will be interesting to see if it influences controversial issues like the fact that the Flash Player is closed source, or that some of Adobe’s open source projects are not as collaborative as they could be.

I suspect though that Adobe is mainly aiming to broaden its technology to encompass web content management and to tie it together with its rich client platform, Flash and AIR. It is a good fit, since it is Java based and should work nicely with the existing LiveCycle pieces. We might also expect integration with Omniture web analytics as well as with the content authoring tools in Creative Suite.

Looks like a sane acquisition to me.
