  dcterms:description "Portable Network Graphics (PNG) was designed for the lossless, portable, compressed storage of raster images. The main reason for the creation of the PNG format was due to a patent issue with the Graphics Interchange Format (GIF) file format. PNG 1.0 was released in 1996 through the World Wide Web Consortium (W3C) and is openly documented. Since PNG is non-proprietary, widely adopted, and has software available for rendering, NARA recommends retaining PNG as-is." ;
