Help:Special property MIME type

The MIME type property is a special property in Semantic MediaWiki with a built-in meaning: it holds the MIME type of an uploaded file. Thus it only works in namespace "File". This special property is available since Semantic MediaWiki 1.9.1 and it is possible to control if this special property is used or not.CiteRef::gh:smw:162 It is disabled by default. See the help page on the configuration setting  for details on configuring SMW for special page related properties including "MIME type".

It can be used like any other property of datatype "Text". This special property should never be set manually, since Semantic MediaWiki will take care of setting its value. Starting with Semantic MediaWiki 2.2.0 it is no longer possible to manually add values for this special property.CiteRef::gh:smw:914

See the property page "MIME type" to see which pages use this special property on this wiki. See also the page about MIME types for an overview of values this special property may hold.
