Basic Definition

Value Name
BINARY
Purpose
This value type is used to identify properties that contain a character encoding of inline binary data. For example, an inline attachment of an object code might be included in an iCalendar object.

Formal Definition

The value type is defined by the following
notation:

  binary     = *(4b-char) [b-end]
  ; A "BASE64" encoded character string, as defined by [RFC 2045].

  b-end      = (2b-char "==") / (3b-char "=")

  b-char = ALPHA / DIGIT / "+" / "/"

Description

Property values with this value type MUST also include the inline encoding parameter sequence of ";ENCODING=BASE64". That is, all inline binary data MUST first be character encoded using the "BASE64" encoding method defined in [RFC 2045]. No additional content value encoding (i.e., BACKSLASH character encoding) is defined for this value type.

Example

The following is an abridged example of a "BASE64" encoded
binary value data.
