[ECODP-dev] ckan2ts

[Bert Van Nuffelen]

Hi Darwin, John and David,

I finally got a bit time to investigate the process ckan -> virtuoso.
The good news is that I could get it working on the odp.tenforce.com
by the next changes
   * a ecodp.ini change to the right namespace
   * adding a file called namespace with the portal namespace in it in
the ckan2ts folder ~/ckan2ts/work/rdf
   * changing the configuration of ckan2ts to let ~/ckan2ts/work/rdf
be the import folder

The bad news is that the rdf-export module of ckan does not produce
valid XML/RDF.

The problem is simple: the dates being entered are declared to be a
xsd:dateTime format but they do not comply to the standard.
Some reference on the XSD:dateTime standard.

Can you put the update to a correct version in this sprint?

A related issue:
   The xmlns abbrevations contain the next abbreviations:

   xmlns:ecodp="http://ec.europa.eu/open-data/ontologies/ec-odp#"
   xmlns="http://ec.europa.eu/open-data/ontologies/ec-odp-example#">

probably we have to change them to the right namespace prefix.
To be discussed what it should be.

kind regards,

Bert
