  2. data URI scheme - Wikipedia

    en.wikipedia.org/wiki/Data_URI_scheme

    A common media type parameter is charset, specifying the character set of the media type, where the value is from the IANA list of character set names. [6] If one is not specified, the media type of the data URI is assumed to be text/plain;charset=US-ASCII. An optional base64 extension base64, separated

  3. Base64 - Wikipedia

    en.wikipedia.org/wiki/Base64

    Base64 is particularly prevalent on the World Wide Web [1] where one of its uses is the ability to embed image files or other binary assets inside textual assets such as HTML and CSS files. [ 2 ] Base64 is also widely used for sending e-mail attachments, because SMTP – in its original form – was designed to transport 7-bit ASCII characters ...

    en.wikipedia.org/wiki/Extensible_Metadata_Platform

    The defined XMP data model can be used to store any set of metadata properties. These can be simple name/value pairs, structured values or lists of values. The data can be nested as well. The XMP standard also defines particular namespaces for defined sets of core properties (e.g. a namespace for the Dublin Core Metadata Element Set). Custom ...

  5. Binary-to-text encoding - Wikipedia

    en.wikipedia.org/wiki/Binary-to-text_encoding

    The ASCII text-encoding standard uses 7 bits to encode characters. With this it is possible to encode 128 (i.e. 2 7) unique values (0–127) to represent the alphabetic, numeric, and punctuation characters commonly used in English, plus a selection of Control characters which do not represent printable characters.

  8. Ascii85 - Wikipedia

    en.wikipedia.org/wiki/Ascii85

    Ascii85, also called Base85, is a form of binary-to-text encoding developed by Paul E. Rutter for the btoa utility. By using five ASCII characters to represent four bytes of binary data (making the encoded size 1 ⁄ 4 larger than the original, assuming eight bits per ASCII character), it is more efficient than uuencode or Base64, which use four characters to represent three bytes of data (1 ...

  9. CBOR - Wikipedia

    en.wikipedia.org/wiki/CBOR

    A tag of 2 indicates that the following byte string encodes an unsigned bignum. A tag of 32 indicates that the following text string is a URI as defined in RFC 3986. RFC 8746 defines tags 64–87 to encode homogeneous arrays of fixed-size integer or floating-point values as byte strings. The tag 55799 is allocated to mean "CBOR data follows".
