3.4.2 GEO Type Definition
To: ietf-mime-directory@imc.org
Subject: Registration of text/directory MIME type GEO
Type name: GEO
Dawson & Howes Standards Track [Page 16]
RFC 2426 vCard MIME Directory Profile September 1998
Type purpose: To specify information related to the global
positioning of the object the vCard represents.
Type encoding: 8bit
Type value: A single structured value consisting of two float values
separated by the SEMI-COLON character (ASCII decimal 59).
Type special notes: This type specifies information related to the
global position of the object associated with the vCard. The value
specifies latitude and longitude, in that order (i.e., "LAT LON"
ordering). The longitude represents the location east and west of the
prime meridian as a positive or negative real number, respectively.
The latitude represents the location north and south of the equator
as a positive or negative real number, respectively. The longitude
and latitude values MUST be specified as decimal degrees and should
be specified to six decimal places. This will allow for granularity
within a meter of the geographical position. The text components are
separated by the SEMI-COLON character (ASCII decimal 59). The simple
formula for converting degrees-minutes-seconds into decimal degrees
is:
decimal = degrees + minutes/60 + seconds/3600.
Type example:
GEO:37.386013;-122.082932

ROLE:Programmer

To: ietf-mime-directory@imc.org
Subject: Registration of text/directory MIME type LOGO

Type value: A single value. The default is binary value. It can also
be reset to uri value. The uri value can be used to specify a value
