Hi list, I would like to discuss some potential optimisations to the csw
server implementation in geoserver. I wanted to use the csw endpoint in
a geoserver training, however I noticed some challenges in the
implementation. For me having a csw service in geoserver makes sense,
because in that case data and metadata are managed in the same system,
things like last update date, title, abstract, contact are always in
sync between wms/wfs-getcapabilities and metadata.
@nielscharlier: Thank you for your suggestion about the metadata
language (on a thread some weeks ago), indeed the metadata language was
the one causing the error (although i still think the error should
indicate which element causus the issue).
A challenge I have with the current implemetation is that I noticed all
metadata elements are in some random order, and this breaks the xsd. How
is the order of the elements applied? Something might be wrong in my
md_metadata.properties, although I think it's a bug in the implemetation.
my md-response has:
<gmd:MD_Metadata>
<gmd:referenceSystemInfo>...
<gmd:dataQualityInfo>...
<gmd:fileIdentifier>...
<gmd:distributionInfo>...
<gmd:language>...
...
Another optimisation to discuss might be to allow to create a
md_metadata.properties per workspace, because in quite some cases layers
in workspace do share some metadata.
Another option I would suggest is to add an option "use internal csw for
metadata links" on the service or workspace level. In that case the
metadata url field will either not be visible, or filled with a default
in the layer-management-form
A last optimisation I would suggest is related to customisation of the
getcapabilities response itself, can it be an option to add a similar
approach as md_metadata.properties to the getcapabilities response?
(INSPIRE requires some custom elements in the getcapabilities response,
and this might be an approach to add them)
