A second approach is to make it two steps in EDG, and it sounds like you’ve done the first. For the second, it’s probably simpler to make another graph based on the more complex ontology as the target and write SHACL Rules (i.e. sh:SPARQLRule) which you can include into the target traph to be executed via the Transform tab to do the conversion. After conversion you un-include the rules graph so you’re left with only the real ontology and data based on it. [Bohms, H.M. (Michel)] Indeed. This is my intention. I did the import-step 1 and now I want to do the step 2 (conversion towards more complex multi-class ontology) with indeed shacl/sparql- rules. (well thought of plain sparql first but I guess better as shacl attached to the targets…). I will study the transform option.
The logic of when/if to create new URIs for things is, however, entirely up to you. Re-generating the same URI many times is fine though, as triples processing means that duplicates cannot be written into the graphs. [Bohms, H.M. (Michel)] That is what I hoped (that the deduplication was automatic)! Will start experimenting, thx for the help, Michel Cheers, David On 21 Sep 2021, at 11:21, 'Bohms, H.M.

In a sense I am splitting the big nonnormalized table into multiple tables. In this process I have to (I assume) create IDs for individuals that were not in the original table (more as just a column there). Is there some standard approach for this (like create only first time when encountered, reuse when already created )? Thank for pointing me to the right resources! Michel Dr. ir. H.M.
