Precision Graphics Markup Language based on Extensible Markup Language
Precision Graphics Markup Language (PGML) is an XML-based language for representing vector graphics. It was a World Wide Web Consortium (W3C) submission by Adobe Systems, IBM, Netscape, and Sun Microsystems, that was not adopted as a recommendation. PGML is a 2D graphical format, offering precision for graphic artists, guaranteeing that the design created will appear in end user systems with the correct formatting, layout and the precision of color.
PGML and Vector Markup Language, another XML-based vector graphics language W3C submission supported by Autodesk, Hewlett-Packard, Macromedia, Microsoft, and Visio Corporation, were later joined and improved upon to create Scalable Vector Graphics (SVG).
