Preferred and allowed document types
Some document types are preferred over others. The reasons for the choice for a specific type are
- sustainability of the type, in other words if the document will still be readable over a long period of time.
- usability in the wikibase, in other words if the software can handle and show it.
Not all document types are allowed. This can be because of a high risk it could damage the system, or it is not usable within the software.
Where possible, files should be converted to the preferred format before uploading, provided this can be done without loss of quality or information.
Document files
Document files can be 'static' (non-editable without specialist software) or 'editable'. Only use editable file formats if there is a need for users to edit the document (for example, a cue list template).
For static documents, PDFs are preferred, as they accurately preserve page layouts, typography and so on. For editable files, open standards are preferred, as they are more likely to be readable in future.
Preferred static file type .pdf type A (this PDF variant is designed for archival use) Allowed file type .pdf
Preferred editable file type .odt (Open Document Text, an Open Document Format type, standardised as ISO 26300) .txt (plain text file - may also be used to contain structured content such as XML) Allowed file types .docx (Microsoft word - .doc files are obsolescent and should be converted to .docx or (preferably) to .odt) .ps (Adobe Post script)

Video
Video file formats involve three parts:
- the video codec (a codec is the definition of how the video is encoded and decoded)
- the audio codec
- the container format, that holds the video and audio data, and metadata about the video.
Preferred video codec For optimum quality: FFV1 For good quality and much smaller file sizes: H.264 or H.265
Preferred audio codec For optimum quality: FLAC, WAV/PCM For good quality and much smaller file sizes: AAC
Preferred container type .mp4 Allowed container type .mkv (container files that support unlimited picture, audio, and subtitle tracks) .avi
3D

Tables
Preferred file type None, tables should only be added as table if the information needs to be interactive, filtered, ... Allowed file type .ods (OpenDocument Spreadsheet) .xlsx (Microsoft Excel - .xls files are obsolescent and should be converted to .xlsx or (preferably) to .ods)
