Hi! I'm not sure about using "has part" for theatres and its twin. In my opinion part of (P361) <-> has part (P527) shouldn't be used for places in general, I would use only location (P276) to indicate the place. What do you think? Thank you very much for the work you are doing and good night!
P361 and theatres
I understand what you mean. I considered the theater as part of the archaeological site. This element is also used in similar cases of temples that are part of archaeological sites (Parthenon). I would be happy to use only the location if that is the case. Do you need if there has been any discussion about this? Perhaps we can start a conversation in the chat page.
In my opinion we should have distinct items for ancient city (Q15661340) and archaeological site (Q839954). I agree about using part of (P361) for rapport with archaeological site (Q839954), while it shouldn't be used with ancient city (Q15661340). Often unfortunately there is confusion between ancient city (Q15661340) and archaeological site (Q839954).
We can discuss at Wikidata talk:WikiProject Ancient Greece, I hope someone will answer our question ;-)
I know. Having distinctive items for ancient city and archaeological site would be great. However, I'm afraid this is really difficult due to the different entries in the various wikipedia languages
