Preface This document explains how Catalog Services version 1.1.1 are organized and implemented for the discovery and retrieval of data and services metadata. The prior public version of this specification was 1.0. Catalog Services version 1.1.1 supercedes and deprecates version 1.0. ii.

Future work Improvements to this document are planned in version 2.0 to incorporate independent efforts within the OGC community to include 1) a “stateless” Web profile of catalog services and 2) interfaces associated with registries of all types of information resource objects. Work on Version 2 will begin by convening a new Revision Working Group in early 2003, with issuance of a revised specification anticipated in late 2003. vii.
