### Parameters:

map=name [required]
  Name of vector map
  Or data source for direct OGR access
organization=phrase
  Organization where vector map was created
date=datestring
  Date of vector map digitization (e.g., "15 Mar 2007")
person=phrase
  Person who created vector map
map_name=phrase
  Vector map title
map_date=datestring
  Date when the source map was originally produced
scale=integer
  Vector map scale number (e.g., 24000)
zone=integer
  Vector map projection zone
threshold=float
  Vector map digitizing threshold number (e.g., 0.5)
comment=phrase
  Text to append to the comment line of the map's metadata file
cmdhist=command
  Command line to store into vector map history file (used for vector scripts)

## DESCRIPTION

v.support is used to set/update vector map metadata. While GRASS GIS typically generates these metadata entries automatically, v.support allows users to manually edit them when necessary.

## EXAMPLE

    # update scale to 1:24000
    v.support myvectmap scale=24000

    # update organization
    v.support myvectmap organization="OSGeo labs"
    v.info myvectmap
