CMS vendor Percussion is pitching their latest Version 6.0 of Rhythmyx not so much as an ECM product solution – but as the core of an interoperability strategy that enables ECM. This seems like a smart approach for a niche solution. The company has added a WSDK (Web Services Software Developer's Kit) and web services API, making it easier to pull and push content into and out of the Rhythmyx repository. Percussion also productized a WYSIWYG web forms tool (à la Ektron) previously developed by a channel partner. That all sounds good, but Rhythmyx V6 doesn't actually release until the end of July and it will be some months before Percussion's customers have put it through its paces. We'll let you know...
