  dcterms:description "Graphics Interchange Format (GIF) is a raster image web graphics format that stores bitmap images in a single file. The 87a version is the original version and 89a was the second release that added support for animation delays, storage of application metadata, and a few other upgrades. The two versions can be distinguished by the first six bytes of the file. GIF 87a was created by CompuServe in 1987 and 89a was released in 1989. GIF used patent-protected LZW lossless compression; the patent was owned by Unisys but expired in 2003. GIF has an open specification and is well-documented and in wide use with a variety of software to render. GIF 87a and 89a are both considered acceptable formats for born-digital posters per NARA Transfer Guidance. It is recommended to retain GIF files as-is since the files can easily be opened and are prevalent in the field. \"Unspecified\" means that we have not yet identified which version of format has been found; these files should be treated as if they possess the risks and limitations inherent in any file in the format family." ;
