Sven V.

Thanks Donny, are there any domains that indicate that an identifier needs to be skolemized? What I am looking for is something that indicates to a different entity that the blank node should be skolemized, like a blank node, but is treated as a constant, like an IRI, by reasoners.

Also, the first link https://www.w3.org/TR/rdf11-concepts/#section-skolemization states "Systems may wish to mint Skolem IRIs in such a way that they can recognize the IRIs as having been introduced solely to replace blank nodes. This allows a system to map IRIs back to blank nodes if needed." I guess I am looking for any such established approaches.

Thanks Dimitris, I have been looking at skolemization a lot. I do have ambitions of one day publishing my data so I would like to use an IRI that indicates that the blank nodes are to be skolemized later, but also specifies that the blank node identifier is a constant. I guess the second link you shared describes a method of assigning hashes as ids. Is that different from an IRI?
