If the parser follows a standard convention like JSON, YAMML, or S Expressions, then you have the choice of maintaining the parser code or a separate database and the queries. I have had almost nothing but trouble with applications which require SQL in its dependency toolchain. They work for months to years, and then an upgrade breaks the DB/app communication. I have had much less problems with using custom YAMML, JSON, and S Expressions in a project as look as it is comes with a reasonable test suite. > Also, you can add your own metadata into a database and a query will > still work with whatever default query LinuxCNC is supplied with.
