___________________________________________________________

Catalogue Service for the Web (CSW) is a standard for providing metadata about geospatial data and services on internet. It allows users to discover and access geospatial resources such as maps, satellite imagery and other data, through a searchable online catalog. 

📌 Note: to get more information about CSW, we invite you to check the <a href="https://www.ogc.org/standards/cat" rel="nofollow noopener noreferrer" target="_blank">standard OGC documentation</a>.

WEkEO Dataset Catalogue is exposed as OGC CSW service via this endpoint: 

https://gateway.prod.wekeo2.eu/elastic-csw/service

Here is the list of operations you can use via the CSW API on WEkEO:

<a href="#h_065289b6c6"><code>GetCapabilities</code></a> to obtain CSW metadata

<a href="#h_850f9f0277"><code>GetRecords</code></a> to search for records and get their metadata

- <a href="#h_065289b6c6"><code>GetCapabilities</code></a> to obtain CSW metadata
- <a href="#h_850f9f0277"><code>GetRecords</code></a> to search for records and get their metadata

The <code>GetCapabilities</code> operation allows CSW clients to retrieve a service metadata from a server. The response to a <code>GetCapabilities</code> request is an XML document containing service metadata about the server:

https://gateway.prod.wekeo2.eu/elastic-csw/service?service=CSW&amp;version=2.0.2&amp;request=GetCapabilities

The <code>GetRecords</code> operation is used to search the catalog and retrieve metadata records that match a specific search criteria. It can also be used to paginate through large result sets.

Following a few examples on how to use <code>GetRecords</code>.
