US: The Open Geospatial Consortium (OGC) has adopted "OGC I15 (ISO19115 Metadata) Extension Package of CS-W ebRIM Profile 1.0." as a standard.
The OGC Catalogue Services Standard establishes a general framework for implementing catalogue services used for publishing and discovering geospatial data and geoprocessing services. The developers of the I15 standard anticipate that this standard will be useful to stakeholders in a wide variety of domains whose spatial metadata conform to the ISO19115 Metadata standard.
The I15 standard provides an extension package aligned with the ebRIM application profile of CS-W for the cataloguing of data and services whose metadata implements ISO geospatial metadata standards. The I15 Extension Package defines mechanisms that allow an ebRIM catalogue to manage and search ISO conformant metadata in ways that enable arbitrary, complex and deep searches involving multiple metadata elements.
The draft standard was initially produced during the ESA HMA (Heterogeneous Missions Accessibility) initiative (HMA) and related projects. The OGC OWS-9 testbed initiative tested the draft standard and provided input.
