The IANA Media Types registry is the official list of media types (MIME types), such as `text/turtle` and `application/json`, maintained by the Internet Assigned Numbers Authority under the procedures of RFC 6838. Each entry links to its registration template and defining specification. It held about 2,360 registered types across ten top-level types when checked on 2026-10-04 (last updated 2026-09-24).

The Internet Assigned Numbers Authority (IANA) maintains the registry of media types, also known as MIME types or content types. A media type has a top-level type and a subtype, such as application/ld+json or text/turtle. Registration procedures are defined in RFC 6838.
The registry is published as one HTML page, one XML file and one text file, plus one CSV file per top-level type: application, audio, font, haptics, image, message, model, multipart, text and video. The example top-level type is reserved for documentation and has no CSV. Row counts in the CSV product descriptions were taken on 2026-10-04.
IANA’s licensing terms dedicate any rights IANA and the IETF hold in the protocol registries to the public domain under CC0 1.0.
The biopragmatics obo-db-ingest project publishes an iana.mediatype conversion of this registry (OBO, OWL, JSON, TSV and SSSOM) at https://w3id.org/biopragmatics/resources/iana.mediatype/. It is not yet listed on the obo-db-ingest page in this registry.
