  "formatDescription": "MXF is a media container format which supports a number of different streams of coded \"essence\", encoded with any of a variety of codecs, together with a metadata wrapper which describes the material contained within the MXF file. \r\n\r\nMXF allows for different degrees of complexity within the wrapper, which are standardised and defined as Operational Patterns, and this may be a consideration for an institution considering preserving the format, hence the separation of these Operational Patterns into separate PUIDs.\r\n\r\nOP3a: A material package that plays out an edit list from one or more file packages where only a single file package may be referenced at any given position on any material package timeline.",
