I’m trying to migrate our existing dataset to Omeka S and everything is working fine so far. I can import CSV files and map the columns to properties. There is one thing I don’t know exactly how to proceed.
Our dataset is, of course, relational. For example do we have an item set with places. Then we do have another item set with agents and those can have birthplace and deathplace as properties. In the mappings configuration of a column > property I can chose Omeka resource (by ID) as data type. But in my provided csv I don’t have the omeka ressource ID, but the ID from the system we had in place before.
How do I import such a case?
Thanks in advance for any tipps on how to solve this
