For publishers, the standardization of a capable scripting language and associated open-source runtime should provide increased confidence in embedding interactivity into next-generation content experiences. There are still issues to be dealt with, including API standardization for archivable interactivity: Flash and the browser still utilize separate DOM interfaces and have other API and capability differences. But there’s no doubt that this is a major advance. It also marks a major step forwards in Adobe’s engagement with the open source and open standards communities. This is not the first and certainly not the last open source contribution by Adobe, but it is definitely the most fundamental so far, and opens the door to other win-win engagements in the future.
