Tango QuickStep Studio is web-based data-publishing software that sorts and organizes various forms of information, and now allows variable graphic and text elements to be dropped directly into QuarkXpress layouts without leaving QuarkXpress, thanks to a free XTension released today. The XTension works with QuarkXpress v8 and currently requires 32-bit mode (a 64-bit version will be released soon, according to Elixir Technologies, the developer).
