OGC® Catalogue Services 3.0 - General Model, Version 3.0.

Abstract

OGC® Catalogue Services support the ability to publish and search collections of descriptive information (metadata records) for geospatial data, services, and related information. Metadata in catalogues represent resource characteristics that can be queried and presented for evaluation and further processing by both humans and software. Catalogue services are required to support the discovery and binding to registered information resources within an information community. This part of the Catalogue Services standard describes the common architecture for OGC Catalogue Services. This document abstractly specifies the interfaces between clients and catalogue services, through the presentation of abstract models. This common architecture is Distributed Computing Platform neutral and uses UML notation. Separate (Part) documents specify the protocol bindings for these Catalogue services, which build upon this document, for the HTTP (or CSW) and OpenSearch protocol bindings. An Abstract Conformance Test Suite is not included in this document. Such Suites shall be developed by protocol bindings and Application Profiles (see 8.5, ISO/IEC TR 10000-2:1998) that realize the conformance classes listed herein. An application profile consists of a set of metadata elements, policies, and guidelines defined for a particular application[1]. OGC document number 14-014 – HTTP Protocol Binding – Abstract Test Suite is available to address conformance with the provisions of OGC document number 12-176r2 – HTTP Protocol Binding. All annexes to this document are informative.
