Energistics, the upstream oil and gas open standards consortium, has published the Energy Industry Profile (EIP) Version 1.0 of ISO 19115-1. The EIP is an open, non-proprietary metadata exchange standard designed to document structured and unstructured information resources of importance to members of the energy community and to maximize metadata interoperability within the industry. Energistics' Geoportal is a Reference Implementation of a searchable catalog compliant with the EIP metadata standard. The implementation demonstrates discovery of distributed resources documented by EIP and any of three metadata standards transformable to EIP (ISO 19115, ISO 19115-2, FGDC).
