1 Zstandard Compression Format29 using the [Zstandard algorithm](http://www.zstandard.org).37 The format uses the Zstandard compression method,58 to compress data into Zstandard format and/or decompress data from Zstandard format.59 The Zstandard format is supported by an open source reference implementation,69 Content compressed by Zstandard is transformed into a Zstandard __frame__.84 - [Zstandard frames](#zstandard-frames)97 Zstandard compressed data is made of one or more __frames__.102 There are two frame formats defined by Zstandard:103 Zstandard frames and Skippable frames.[all …]
