for harvesting service metadata from OGC web services. To enable this capabilities documents of the OWS will be accessed and transformed into a valid format that will be understood by the underlying catalogue. To enable a lot of flexibility a XSLT read from resource bundle (harvestservice.xsl) script will be used to perform the required transformation.

A valid harvest SOURCE for a service must be a complete GetCapabilities request; the RESOURCETYPE must be 'service'. Example:

...?request=Harvest&version=2.0.0&source=[http://MyServer:8080/deegree? service=WFS&version=1.1.0&request=GetCapabilities]&resourceType=service& resourceFormat=text/xml&responseHandler=mailto:info@lat-lon.de&harvestInterval=P2W

value in brackets [..] must be URL encoded and send without brackets!

This is not absolutly compliant to OGc CSW 2.0.0 specification but Harvest definition as available from the spec is to limited because it just targets single metadata documents.
