Context
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 standard OGC documentation.
WEkEO Dataset Catalogue is exposed as OGC CSW service via this endpoint:
https://pn-csw.prod.wekeo2.eu/elastic-csw/service
Here is the list of operations you can use via the CSW API on WEkEO:
GetCapabilitiesto obtain CSW metadataGetRecordsto search for records and get their metadata
CSW operations
GetCapabilities
The GetCapabilities operation allows CSW clients to retrieve a service metadata from a server. The response to a GetCapabilities request is an XML document containing service metadata about the server:

GetRecords
The GetRecords 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 GetRecords.
