mime-types 2.5

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 add additional type definitions (see Contributing.rdoc). The primary sources for MIME type definitions found in mime-types is the {IANA Media Types registry}[https://www.iana.org/assignments/media-types/media-types.xhtml], RFCs, and W3C recommendations. It conforms to RFCs 2045 and 2231. This is release 2.5 with a couple of bug fixes, updating to the latest IANA type registry, and adding a user-contributed type. mime-types 2.x supports Ruby 1.9.2 or later.
