Dependency version conflict with PyCSW

[rossjones]

Depending on the version of PyCSW you install, you may encounter a problem running the ckan-pycsw paster command with:

pkg_resources.ContextualVersionConflict:
 (OWSLib 0.8.6 (/usr/lib/venv/lib/python2.7/site-packages), 
Requirement.parse('OWSLib==0.16.0'), set(['pycsw']))

This is because ckanext-spatial requires 0.8.6 whereas pycsw after a certain version uses more recent OWSLib.

---

I've worked around this by installing a newer OWSLib, not yet sure what effect it has on the running of ckanext-spatial.

I'm pretty sure we can upgrade the ckanext-spatial requirement to align it with pycsw, but I haven't work on the harvesters for a long time. Do you think there will be an issue @tomkralidis? ie are there major API changes from that version?

[tomkralidis]

@amercader there’s nothing breaking in OWSLib AFAICT.

[rossjones]

It does seem to be okay in actual use, but the tests do break when I update owslib, but I think it's probably the test being wrong.

The problem is likely at https://github.com/ckan/ckanext-spatial/blob/master/ckanext/spatial/harvesters/base.py#L386 (it only adds the verified field when true) .. but I'm afraid I'm out of time to dig deeper.

Maybe a Good for contribution tag?

@amercader @tomkralidis @rossjones is there any update to this? We are trying to use the most updated version of spatial but some of our imports fail because OWSLib is not up to date
