Web Open Font Format
Description
"WOFF combines the work of Leming and Blokland had done on embedding a variety of useful font metadata with the font resource compression that Kew had developed. The end result is a format that includes optimized compression that reduces the download time needed to load font resources while incorporating information about the font's origin and licensing. The format doesn't include any encryption or DRM, so it should be universally accepted by browser vendors—this should also qualify it for adoption by the W3C."
