Is there an agreed international standard on metadata for geographic information?
No, an official international standard does not exist yet. However, the International Standardisation Organisation (ISO) is developing in its Technical Committee 211 a family of standards related to geo-spatial information (http://www.statkart.no/isotc211/pow.htm), including one for metadata, IS 19115. Work on this standard has been going on for five years and is in its final stages. Version 3 of the Draft standard was published in June 2000, and comments are expected by the 1st September. A final draft will be prepared in November and the International Standard is expected to be issued in July 2001.
