AGS checker: line-by-line AGS4 file validation
An AGS4 data file is checked against the format rules: row syntax, group composition, data types, in-file dictionaries and key links. Every finding is tied to a file line and a rule number, so fixes go straight into the source file.

What counts as an error and what as a warning?
An error is a direct violation of a format rule: broken syntax, field count mismatch, a wrong data type, a reference to a non-existent borehole or sample. A warning is a doubtful spot that cannot be proven without the reference dictionary: a unit or data type missing from the in-file dictionaries, a heading outside the naming format.
Is the AGS standard dictionary checked?
No: the reference dictionary of groups and headings (rule 9) is not built in. The checker validates the dictionaries of the file itself: the TYPE, UNIT and ABBR groups, and heading names are checked against the naming format.
Is the file stored?
No: the check runs in memory, the content is not written anywhere or passed to third parties.
