For environmental datasets to be used effectively via the Internet, they must present standardized data and metadata services and link the two. The Open Geospatial Consortium's (OGC) web services (WFS, WMS, CSW etc.), have seen widespread use over many years however few organizations have deployed information architectures based solely on OGC standards for all their datasets. Collections of organizations within a thematically-based community certainly cannot realistically be expected to do so. To enable service use flexibility we present a services framework - a Data Brokering Layer (DBL). A DBL presents access to data and metadata services for datasets, and links between them, in a standardized manner based on Linked Data and Semantic Web principles. By specifying regular access methods to any data or metadata service relevant for a dataset, community organizers allow a wide range of services for use within their community. Additionally, a community service profile testing service – a Conformance Service – may be run that reveals the day-to-day status of all of a community’s services to be known allowing both better end-user experiences and also that data providers’ data is acceptable to a community and continues to remains available for use. We present DBL and Conformance Service designs as well as a whole-of-community architecture that facilitates the use of the two. We describe implementations of them within two Australian environmental information communities: eReefs and Bioregional Assessments and plans for wider deployment.
