The new standard CSW 3.0, published on March 18, 2014, was edited by Lorenzo Bigagli, Doug Nebert, Uwe Voges, Panagiotis Vretanos, and Bruce Westcott. The main areas of enhancement in CSW3.0 with regard to CSW 2.0.2 include: 10 • Restructuring the specification document according to the OGC standard for modular specifications OGC 08-131r3, also know as Core and Extension model. • Incorporating the current mass-market technologies for discovery on the Web namely OpenSearch. • Providing a better scenario design to support distributed and federated search. The standard contains the following main content: • General Model • Hypertext Transfer Protocol HTTP Protocol Binding. In CSW, the GETKVP encoding is mandatory. The POSTXML encoding is optional. SOAP is supported as a special case of the POSTXML encoding. • The OpenSearch is mandatory in CSW 3.0, no matter which implementation profile is used in the catalogue instance. The OpenSearch Geospatial and
