AB: Assay data is a key information type used in the solid earth sciences, particularly for mineral exploration. As well as its conceptual importance it comprises a significant proportion of data transferred between organizations. In collaboration with both the commercial and regulatory sector, we have developed an XML encoding for assay data. The Assay Data Exchange (ADX) encoding is a GML Application Schema, based on the Observations and Measurements recommendation from Open Geospatial Consortium (OGC), extended with assay specific attributes. The model is normalized, distinguishing the observation event and result from the observation target (specimen) and procedure (instrument). ADX has been used in the deployment of standard web-service interfaces to the archives of agencies who are custodians of such data (geological surveys). The web-service interface is a profile of the standard http-based OGC Web Feature Service. Map-visualization and tabular-report web-clients have been deployed that access these services. In addition, a number of standard data processing and visualization software packages have been enhanced to act as clients to these sources. The immediate value of the standard format and interface is that it enables lossless transfer of assay data from laboratory to explorer, from explorer to regulator, and then from statutory custodian back to speculative explorer, using a common format. This represents the complete data transfer cycle relevant to the mineral exploration industry. However, the more general value of the project is that it demonstrates the efficiencies that can be gained by standardizing data access protocols, and the use of a consensus process within the appropriate community for design of technical standards constructed as profiles of more generic standards.
