[GeoNode-users] GeoNode - PyCSW integration issues

[Alessio Fabiani]

Dear all,
I want to highlight some important issues about the current integration
between GeoNode and PyCSW.

Other than a non-trivial security issue (basically the CSW exposes metadata
for all Layers no matter if they are accessible or not by the user), one
more, I would say, big issue is that currently is not possible to recognize
the Layer "real name" from the metadata documents.

Let me provide an example. Here below a snippet of a DublinCore XML
produced by PyCSW

...
<csw:Record>
    <dc:identifier>941a8d7e-7159-11e7-b283-002215079c40</dc:identifier>
    <dc:title>san_andres_y_providencia_highway</dc:title>
    <dc:type>dataset</dc:type>
    <dc:subject/>
    ...
    <dct:references scheme="WWW:DOWNLOAD-1.0-http--download">
http://localhost:8080/geoserver/wms?request=GetLegendGraphic&format=image/png&WIDTH=20&HEIGHT=20&LAYER=geonode:san_andres_y_providencia_highway&legend_options=fontAntiAliasing:true;fontSize:12;forceLabels:on
</dct:references>
    <dct:references scheme="OGC:WMS">
http://localhost:8080/geoserver/geonode/wms</dct:references>
    <dct:references scheme="OGC:WFS">
http://localhost:8080/geoserver/geonode/wfs</dct:references>
...

(full XML here https://pastebin.com/Wu0vm79B)

Seems to be good right? *Wrong!* There some important things missing here:

1. It is not possible to recognize the layer name at all; The element
"title" is mapped to the resource title, meaning that whenever I change it
on the metadata into a human readable fashion, I lose the layer name forever

2. Layer qualified name is missing; if the name had a namespace, like on
GeoServer, it is not possible to know which is at all

3. WMS and WFS links cannot be used at all, since the layer name cannot be
retrieved anywhere

*Proposal*

Following the notes written by Stephen Richard here
https://github.com/geopython/pycsw/wiki/Geonode-notes

the proposal here would be to add more references

OGC:WMS-1.1.1-http-get-capabilities
OGC:WMS-1.3.0-http-get-capabilities
OGC:WMS-1.1.1-http-get-map
OGC:WMS-1.3.0-http-get-map
OGC:WMS-1.1.1-http-get-featureinfo
OGC:WMS-1.3.0-http-get-featureinfo

OGC:WFS-1.0.0-http-get-capabilities
OGC:WFS-1.0.0-http-describe-feature
OGC:WFS-1.0.0-http-get-feature

OGC:WCS-1.1.0-http-get-capabilities
OGC:WCS-1.1.0-http-describe-coverage
OGC:WCS-1.1.0-http-get-coverage
...

in order to let CSW being able to send correct links to the clients.

If there are no objections, I will create a PR accordingly related to the
following ISSUE
