  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 was first released in 1996 through the World Wide Web Consortium (W3C) and version 1.2 was released in 1999 to add the iTXt chunk to the specification. The specification for PNG 1.2 was later standardized by ISO in 2004. PNG 1.2 is considered a preferred or acceptable format, depending on the record category, per NARA Transfer Guidance. Since PNG is non-proprietary, widely adopted, and has software available for rendering, NARA recommends retaining PNG as-is." ;
