The main objectives in the development of DIGGS V2.0a from V1.0a were to:

1. Bring DIGGS into compliance with Geography Markup Language (GML),
2. Address the schema complexity of DIGGS 1.0a and corresponding performance issues with XML software to remove the technical barriers to adoption,
3. Apply modeling best practices and improve the usability of DIGGS,
4. Update to the latest version of GML,
5. Enrich/refine the geotechnical and geoenvironmental domain model,
6. Improve/test implementability of DIGGS

Much of the technical developments toward the listed objectives were accomplished between Jan 2011 and June 2012.
