Mapping from extension to MIME type

This is a programmatically generated character vector whose names identify the MIME type typically associated with the extension which are the values. This is used in guessMIMEType. We can match an extension and then find the corresponding MIME type. There are duplicates.

data(mimeTypeExtensions)

Format

The format is a named character vector where the names are the MIME types and the values are the file extensions.

Source

The table of MIME types and extensions was programmatically extracted from http://www.webmaster-toolkit.com/mime-types.shtml with tbls = readHTMLTable("http://www.webmaster-toolkit.com/mime-types.shtml") tmp = tbls[[1]][-1,] mimeTypeExtensions = structure(as.character(tmp[[2]]), names = gsub("^\.", "", tmp[[1]])) save(mimeTypeExtensions, file = "data/mimeTypeExtensions.rda") The IANA list is not as convenient to programmatically compile.
