Hi Stefan,

thanks for your detailed answer! And nice to see that you provide English 
documentation for your profile.

Regards,
Florian

Hi Florian,

I'm part of the team that implemented DCAT-AP Switzerland for 
opendata.swiss, an CKAN-based opendata portal for Switzerland.

We rely on ckanext-dcat, you can find the source here: 
https://github.com/opendata-swiss/ckanext-switzerland/blob/master/ckanext/switzerland/dcat/profiles.py
DCAT-AP Switzerland is based on the European DCAT-AP standard, but has 
some fields that are used differently. As a help for the data publishers 
we setup a handbook with the documentation, so that they have a reference 
guide: http://handbook.opendata.swiss/en/library/ch-dcat-ap

The portal provides 3 ways for data provides to add new datasets:

1. Add them manually using the WordPress backend of opendata.swiss (the 
source code of this backend can be found here: 
https://github.com/opendata-swiss/wp-ckan-backend)
2. Upload a valid DCAT-AP Switzerland XML in the WordPress backend of 
opendata.swiss
3. Provide a DCAT-AP Switzerland RDF harvester source, we then use the 
harvester provided by ckanext-dcat to harvest these data providers (
https://github.com/ckan/ckanext-dcat#rdf-dcat-harvester)

Our learnings:
- Get feedback from the data providers early on
- If possible, provide a validator for your DCAT-AP profile
- If possible, provide an export functionality for manually entered data, 
so that less experienced users have an easy way to "generate" a valid 
example

Feel free to contact me if you have further questions.

Best regards Stefan

Dear Tim, 

your profile would definitely be a great help! Since others may be in the 
same situation as me you could also think about posting the files on 
GitHub or something similar. 

Regards, 
Florian
