harvesting from CKAN and ESRI products

Travis Kirstine
Sorry I'm a bit of noob when it comes to metadata and CSW services and was hoping someone in the pycsw community could provide some insight.  My region has seen the growth of open data portals at all levels of gov't, most of which are using either ESRI's geohub or CKAN.  This is all great however it makes finding information difficult as you don't know which level of gov't or portal to access.  We'd like to aggregate this information into a common catalog (pycsw) through an automated process and then utilize the APIs and links to OWS / ESRI rest services provided on the portals to add the information to a web based map.  I know that HHypermap was doing something similar but it is more than we are looking for and the project no longer seems active.

Does anyone know of other projects or tools out there doing this sort of thing?  My organization has fairly limited resources and this seems like a fairly large undertaking at this point.

Any insight would be greatly appreciated.

Hi Travis: no apology necessary :)

HHypermap would be a good choice (although, as you mention, it does more
than harvesting and likely needs some updating).  You could also implement metadata
parsers into pycsw proper (we don't support ESRI geohub or CKAN harvest, but contributions
are welcome) and implement harvesters to leverage the CSW transactional workflow or
using pycsw as a library from your own Python application.
