The mime-types library provides a library and registry for information about MIME content type definitions. It can be used to determine defined filename extensions for MIME types, or to use filename extensions to look up the likely MIME type definitions. MIME content types are used in MIME-compliant communications, as in e-mail or HTTP traffic, to indicate the type of content which is transmitted. The mime-types library provides the ability for detailed information about MIME entities (provided as an enumerable collection of MIME::Type objects) to be determined and used programmatically. There are many types defined by RFCs and vendors, so the list is long but by definition incomplete; don't hesitate to to add additional type definitions (see Contributing.rdoc). The primary sources for MIME type definitions found in mime-types is the IANA collection of registrations (see below for the link), RFCs, and W3C recommendations. This is release 2.2, mostly changing how the MIME type registry is updated from the IANA registry (the format of which was incompatibly changed shortly before this release) and taking advantage of the extra data available from IANA registry in the form of MIME::Type#xrefs. In addition, the {LTSW list}[http://www.ltsw.se/knbase/internet/mime.htp] has been dropped as a supported list. As a reminder, mime-types 2.x is no longer compatible with Ruby 1.8 and mime-types 1.x is only being maintained for security issues. No new MIME types or features will be added. mime-types (previously called MIME::Types for Ruby) was originally based on MIME::Types for Perl by Mark Overmeer, copyright 2001 - 2009. It is built to conform to the MIME types of RFCs 2045 and 2231. It tracks the {IANA Media Types registry}[https://www.iana.org/assignments/media-types/media-types.xhtml] with some types added by the users of mime-types.
