AB: Accurate constraints on the chemistry of hydrothermal fluids are critical in our capacity to computationally model and simulate how ore deposits form. To maximize results and subsequent interpretation the fluid inclusion populations should be fully characterized using standardised observational and processing techniques. A Virtual Centre for Geofluids and Thermodynamic Data, which includes the fluid inclusion (FIncs) system, has been established to achieve this. The FIncs system is designed to pull together fluid inclusion data from many individual, often disparate studies. The FIncs database and web applications allow researchers to search and retrieve fluid inclusion data and images via a web browser interface. The database will help standardise the way fluid inclusion data and associated metadata are stored. Furthermore, it follows the principles outlined by the Open Geospatial Consortium (OGC) for the Observation and Measurement application schema. It is tightly coupled to enable formalisation of the observations and measurements made on fluid inclusions, and to standardise how these measurements are processed to achieve consistent constraints for geochemical models. FIncs uses both domain factual knowledge and problem-solving knowledge by providing a choice of models (equations of state) for obtaining additional fluid properties via a web-based calculator, which allows researchers to calculate isochoric T&P values and other chemical and physical properties (e.g. salinity, density, etc.). This method has the benefit of ensuring that all derived data are produced and standardised by a selected set of routines. It also enables data from multiple sources to be quickly reprocessed by new routines as they become available and are added to the database toolkit. The database is being developed as an "open" project, which intends to bring together researchers interested in the properties of geological fluids or fluid inclusions. The ultimate goal of the Virtual Centre for Geofluids information system is to provide machine-to-machine (software-to-software) data readability, enabling more or less seamless integration of different datasets and computer codes. In future, users' applications will be able to access the system as web-services using XML.
