DCAT Dataset URIs - Githubissues

Hello,

I was wondering whether anyone could provide me with some insights on an issue I am experiencing when importing DCAT records into CKAN.

I have a large set of dataset records in DCAT format that I can successfully import into CKAN using the DCAT Harvester. When the harvesting takes place, the dataset URIs and IDs from the DCAT records are mapped as extra:uri and extra:identifier data fields. CKAN automatically generates an additional URI and ID data field for each dataset using the ckanext.dcat.base_uri configuration of my CKAN instance.

This of course makes sense for cases where the harvested URIs are in a different format to those generated by the CKAN instance. However, I have specifically modelled the URIs and IDs in my dataset records to follow the configuration of my CKAN instance. As such I am trying to figure out a way that my harvested URIs and IDs will be mapped as the main CKAN URI and ID data fields (and not just the extra:uri and extra:identifier fields). Would anyone have advice on how to implement this?

Below is a sample of the DCAT records that I am harvesting into CKAN. Here the datasets have URIs and IDs in the same format as those of my CKAN instance. These URIs and IDs are currently being imported as extra:uri and extra:identifier. This causes the following:

If I enter https://myckansite.ie/MyCKANSiteName/dataset/4fd42b48-507b-4a9e-ba6a-c88245cb9ce1 into my CKAN instance I am brought to a 404 not found error.
However, if I enter the new URI generated by CKAN I am brought to the dataset page.
On the other hand, if I view the RDF endpoint of a harvested dataset, the DCAT record displays the original URI and ID (i.e. the extra:uri and extra:identifier) and not the new URI generated by CKAN.

Thank you, Lucy @lucymc12
