Each line in a GAV schema file begins with a "token" or a "descriptor". These are special keywords used in defining the format of the data. The first line of a schema file must contain only the token "GAV". This identifies the file as a GAV schema file. The remaining lines in the schema file describe the format of the data in the GAV data file.
A GAV schema file can contain comments. Comment lines begin with an exclamation mark (!) character. Comment lines and blank lines are ignored.
The following is a list of GAV descriptors:
NAME
CATEGORY
OFFSET
SEPARATOR_CHAR
SEPARATOR_CHARS
SEPARATORCHARS_ASONE
HAS_COORDFIELD
COMMENT_CHAR
COMMENT_CHARS
MAPUNITS
METADATA
METADATA_SEPARATOR
LAYER_END
LAYER_END_REUSE
DATA
ROWS
The descriptors SEPARATOR_CHAR and SEPARATOR_CHARS are equivalent, as are COMMENT_CHAR AND COMMENT_CHARS.
GAV descriptors are case insensitive.
