Catalogue Service for the Web (CSW)
Last Updated 2 years ago

1. Introduction

Catalogue Service for the Web is an OGC standard defined for publishing (geospatial) metadata information in a standardized way. EODC provides such a catalog and this guide will show some basic requests that fetch metadata.

Catalogue services support the ability to publish and search collections of descriptive information (metadata) for data, services, and related information objects. 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.
