| # Enumerated Media Types |
| # ---------------------- |
| # |
| # This is a curated list of about 200 common Media Types (also known as MIME |
| # Types). The official name, with variable length, is in the fourth column. A |
| # fixed length contraction, presented in 4/4/2 format, is in the third column. |
| # The base38 numeric encoding of that 4/4/2 string is in the first (hex) and |
| # second (decimal) columns. These positive numbers are all less than or equal |
| # to ((1<<53)-1), also known as Number.MAX_SAFE_INTEGER in JavaScript, and so |
| # generally safe to pass around as a JSON value, float64, int64 or uint64. |
| # |
| # As an int64 or uint64, the high 32 bits (of which only 21 are used) hold the |
| # top-level type: 0x09CC62 means "application", 0x106BF7 means "image", etc. |
| # |
| # Using fixed-size numbers instead of variable-length strings can be useful in |
| # file formats, wire protocols, database tables or other contexts where dynamic |
| # memory allocation is unavailable or fallible or where variable-length data |
| # complicates matters. At the micro-optimization level, comparing or hashing |
| # uint64 numbers is also faster than for arbitrary strings. |
| # |
| # Using a sparse enumeration (instead of the dense 1 = "application/epub+zip", |
| # 2 = "application/java-archive", etc) means that, when debugging or logging, |
| # the numerical value can be converted to a somewhat-human-readable form (the |
| # "appl/java/ar" 4/4/2 string) purely algorithmically, without a lookup table. |
| # Inserting new entries can also preserve the sortedness of the 4/4/2 form |
| # without requiring renumbering. |
| # |
| # When debugging, if the numerical value is all that you know, grepping a large |
| # codebase for 0x09CC62_880DB9BE or 2757998351858110 will also produce far |
| # fewer false positives than grepping for 2. |
| # |
| # The pua.example subtypes (e.g. for private use within a system that deals |
| # with "foobar.example" files) are an unofficial suggestion for entries not in |
| # the official IANA registry, similar to Unicode's Private Use Area. For a PUA |
| # entry's 4/4/2 string, the middle-4 starts with a "~" (and cannot be "~~~~") |
| # but the rest of the middle-4-right-2 is freeform. |
| # |
| # The official IANA Media Types registry: |
| # https://www.iana.org/assignments/media-types/media-types.xhtml |
| # |
| # A popular subset of that registry, with about 800 entries, as well as a |
| # mapping between Media Types (like "application/java-archive") and filename |
| # extensions (like ".jar"): |
| # https://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types |
| # |
| # This file (enumerated-media-types.txt) is canonically hosted in the doc/note |
| # directory of the github.com/google/wuffs repository. That same directory also |
| # holds a base38-and-fourcc.md file that elaborates on base38 encoding. |
