Multiple values of a facet? #7

Closed borsna closed 10 years ago

borsna commented 10 years ago

For the mapping eg. for the 'Subject' facet multiple values is needed. This is also something we need for other facets. I have marked possible multiples or single value facets in the overview document: https://docs.google.com/spreadsheets/d/1-2sP5cQj4wN8NptHRgzIiuGruL7HA1F2Hu2bM_HTbdQ/edit

Is this in line of the work done in the mapping tool and the portal?

Dear Olof,

thanks for your message. This is a good point. It is always possible to create a list of values. Dublin Core supports this. There is subtle issue when implementing a catalog however. While any field that can show a string can also show a list of strings, when using such a list the relation between the values from the perspective of the database is lost. I think that for the moment it is safe to assume that the catalogue can work with lists in terms of strings, but not in terms of the database. However, tomorrow I will ask our expert. Please note that discussions about this take place in the ckan forum.

https://github.com/ckan/ckan/issues/1365

Anyway, I will confirm as soon as I know the exact in and outs of the ckan interpretation of 'multiple values'.

Hope that you can work with this for the moment.

Best wishes,

Hi Kees Jan, Is the handling of multiple values for the import done as in the example https://github.com/DASISH/md-mapping/blob/master/mapfiles/cmdi.xml#L27 for all facets (first;second;third)? If so i will make a note of this in the documentation.
