[ckan-dev] Temporal extent ingest failing in CSW spatial harvester?

[Bruce Crevensten]

Hi, I'm working on a custom harvester that extends the CSW harvester and
while most ISO fields are coming through, the ingest of temporal extent is
failing.  We're harvesting from GeoNetwork and an example specimen we're
ingesting is here:

https://athena.snap.uaf.edu/geonetwork/srv/xml.metadata.get?id=22

The XPath expressions in the relevant ISODocument code
<https://github.com/ckan/ckanext-spatial/blob/master/ckanext/spatial/model/harvested_metadata.py#L762>
looks like it should be working and I confirmed in a 3rd party tool that
they do, in fact, work.  I tried a few varying paths in the extended
get_package_dict function, but no luck.  I also tried running the built-in
CSW harvester (getting my custom code out of the loop), but it also fails
to capture temporal extent.

Other XPath expressions I'm using to pull out data from the harvest source
are working, and the ISODocument is reasonably complete (there are places
where our metadata may not be entered into GeoNetwork in a way that CKAN
understands, but the Temporal Extent looks solid).

Our CSW endpoint for this harvest job is here:

https://athena.snap.uaf.edu/geonetwork/srv/en/csw?request=GetCapabilities&service=CSW

It doesn't seem like we have a malformed document or XPath, so I almost
wonder if this relates to a lower-level Python or other system
configuration in some way?  We're running:

CentOS 6.5
CKAN 2.2.1 (from source install)
Python 2.2.6
LibXML 20900

Ingest of temporal extent also fails using a CKAN 2.0 install we're running
on a similar platform (same versions of libraries listed above).

If any developer were able to try a CSW harvest job using a known-good
installation or could give some suggestions on where to look next, it would
be much appreciated!
