RIP Scalable Vector Graphics (SVG).
Deprecated equals don’t use it. The momentum in the web-world has slowed to grinding halt.
Whilst SVG is a W3C technology, not owned by Adobe, the original specification came from PGML.
Sad, there was much potential for SVG. All it would have taken was Adobe to make a standard programming model and builder application and SVG really could have taken off. SVG is an example of good technology becoming cannon fodder, lost in the charge to an enemy: rather than technology being used for good.
Today, we have two XML-based model for generating rich interfaces: MXML and XAML. One is in the operating system and a part of a download, the other requires a bolt-on application in the browser.
SVG pre-dated these technologies by some years. A standardised widget library; extension into 3D and co-operation by large companies could have advanced the world of rich, connected applications.
Standard file formats invite competitiveness in software applications. Consider open, standardised file formats like world-free trade. The most efficient and best survive. A darwinian selection for the best.
Better luck next time.
