AbstractGWML2 is a new international standard for the online exchange of groundwater data, developed by an international consortium of major groundwater data providers. It addresses the data heterogeneity problem, in which the data needed to manage groundwater resources is typically distributed amongst multiple agencies making it challenging to find and use. Overcoming this challenge requires a common data representation, however until the development of GWML2 the groundwater community has lacked an internationally sanctioned groundwater data exchange standard. GWML2 represents key entities relevant to hydrogeology such as aquifers, water wells, groundwater flow and fluid properties. It is developed rigorously using an innovative three-part methodology, resulting in conceptual, logical, and encoding schemas, and is tested by major groundwater data providers in North America, Europe, and Australasia. GWML2 facilitates many forms of data exchange and information representation, as well interoperability between groundwater data networks.
