In 2009, we produced a guide to file formats for the Media Working Group. The following requirements were taken into account
I Web-delivery: files need to be easily viewed in browser, this pertains both to bandwidth issues (which affects the time it takes to view objects) and wider support (some formats require plug-ins to be viewed in browsers)
I Open standards: non-proprietary formats are preferred as software vendors can go out of business, start charging for certain usage, also proprietary formats can be patent-encumbered
I Compliance with IR funding bodies
I Preservation: formats should be easily migrated and normalised to preservation standard
