Mars Bar

Just noticed that there is now (as of last month) a blog for Mars (“Mars: Comments on PDF, Acrobat, XML, and the Mars file format”). See this from the initial post:

“The Mars Project at Adobe is aimed at creating an XML representation for PDF documents. We use a component-based model for representing different aspects of the document and we use the Universal Container Format (a Zip-based packaging format) to hold the pieces. Mars uses XML to represent the individual components where that makes sense, but otherwise uses industry standard formats to represent other components. Examples of these include Fonts (we use OpenType), Images (PNG, GIF, JPEG, JPEG2000), Color (ICC Color Profiles), etc.. We use SVG to represent page content, which fits as both an XML format and an industry standard.”
