The prototype is written in an Object-oriented language and style (Perl 5). Release 0.1, a tarred, gzipped version of the code is SemiStructured.tar.gz (180KB) can be downloaded.
- This is a prototype system. There will be bugs and other gotchas. Several known unimplemented features have been documented. Please send comments and bug reports to Curtis.Dyreson at usu.edu.
- The code is documented using POD, see the on-line documentation.
- The code is stand-alone, and does not use any non-standard Perl packages. In the current release it is configured to use Berkeley BSD (see BerkeleyDB at CPAN), but can be configured to use and DBM implementation as the underlying database (e.g., GDBM). For more information see OODatabase.
- The parser is generated with the excellent Parse::Yapp package written and maintained by Francois Desarmenien. Parse::Yapp can be found at CPAN. Version 1.0 of Parse::Yapp is provided in the installation so that you can make changes to the SELECT or INSERT BNF if desired, but the existing version of AUCQL is independent of Parse::Yapp.
