ChatGPT's answer:
In RDF/OWL semantics, properties and classes are assumed to be open. Thus, stating new information doesn't overwrite old information but adds to it. If these statements are in the same named graph or different ones, it won't matter in terms of the overall inferred model:
:login_datewill include:table_1,:table_2, and:table_3in its domain. This is assuming default behavior and settings; specific behavior might be influenced by the database's configuration or the application querying it.
Sounds sensible to me! Would a knowledgeable knowledge graph person be so kind as to verify?
