General eXchange Format (GXF) is a file exchange format for the

transfer of simple and compound clips between television program storage systems. It is a container format that can contain Motion JPEG (M-JPEG), MPEG, or DV-based video compression standards, with associated audio, time code, and user data that may include user-defined metadata.

GXF was developed by Grass Valley Group, then standardized by SMPTE as SMPTE 360M,[http://store.smpte.org/product-p/smpte%200360-2009.htm SMPTE 360M] and was extended in SMPTE RDD 14-2007[http://store.smpte.org/product-p/rdd%2014-2007.htm SMPTE RDD 14-2007] to include high-definition video resolutions.

GXF has a fairly simple data model compared with SMPTE MXF container format since it should be used for file transfers and not as a storage format with no editing capabilities.[http://broadcastengineering.com/mag/broadcasting_file_interchange_formats/ File interchange formats] SMPTE RDD 14-2007 is only 57 pages long, compared with many hundreds of pages for the MXF standards.
