Reader Overview
The CSW reader queries a CSW compliant server for catalogue records with a search.
Every record returned from the search is represented by the CSW reader with a single feature type.
The CSW reader currently supports searching for records using either text-based and/or bounding-box-based methods. Please refer to the Search Settings for information about specifying a search text, or Use Search Envelope for information about specifying a bounding box. The search text provided by the user will be the feature type for all the records returned in that search. If the search text was not provided, the feature type will be set to CSW Records.
Writer Overview
The CSW writer can perform transactions on a CSW compliant server.
A transaction request can insert, update, or delete catalogue records on the CSW server.
The CSW writer currently supports 2 feature types: CSW_Records and Other.
For CSW servers that use the csw:Record schema to store catalogue records, CSW_Records feature type should be used to perform transactions on the server. For all other types of records, use the Other feature type. The record will be retrieved from the record_xml_frag attribute on the Other features.
