Open Vector File Format is a format that was introduced in 1997
by XARA to compete with the Macromedia Flash
format. The format was open and developers could export from their products to this format, royalty free and without the need of any permission. The key characteristic and design goal was for a file format that was very compact for fast download over the internet. It supports a rich set of vector graphic
primitives including a wide variety of graduated shading and graduated transparency
The Xara Flare format was also the native file format used in the Xara X vector graphics software. In 2004 it was updated and renamed the Xar file format.
