Re: [GeoNetwork-users] Access Geonetwork via Python-Skript

[Lars M. <lar...@hz...>]

Hello Andreas,

another recommendation would be to use the python library owslib 
<https://geopython.github.io/OWSLib/index.html> by Tom Kralidis that 
offers various interactions with ogc-compliant APIs including CSW. It 
has nice wrapper tools in owslib.utils that might support you in what 
you are trying to do. At least it is handling the authentication, cookie 
or XR…F(?) token exchange etc. and also uses the requests class for the 
connection.

But another thing - I wasn't aware you could add attachments to metadata 
entries. Is the attachment you want to download really 'physically 
bound' to geonetwork file structure, or added via a reference? If so, 
you could first extract its link from the metadata entry and then 
download from the linked resource.

Cheers,
Lars
