XML Goo-i-ness Inside

Microsoft pre-released their XAML-in-the-browser technology, WPF/e earlier this week. XAML inside.

XAML “smells” like the W3C’s Scalable Vector Graphics (SVG). DOM-inside-a-DOM, Declarative animation, 2D graphics. XAML maybe not SVG, but it certainly tips its hat to SVG.

Adobe today pre-released their XML-in-a-PDF technology, Mars, for Acrobat 8. Essentially, Mars as a technology is presently delivered as plugins for Adobe Reader 8 and Acrobat 8 Professional. You can save an existing ‘binary’ PDF out as a .mars file. These .mars files are like .jar or .war files: manifested, structured ZIP files. Looking inside a description of a page, you have an SVG Tiny 1.2+ (as Adobe state, SVG/FSS0 representation. The specification clearly documents that .mars takes the current concept of PDF, a document format, and extends this as XML.These technologies do not directly intersect: an XML representation of SWF rather than PDF would be closer to XAML. Having cross-platform viewer support for Microsoft’s XPS would be closer to PDF.

I was premature in saying SVG was deprecated.
