Hi.

apartments inside a big building?

I guess you meant samePlaceAs - owl:sameAs is much too specific for that
case.

Saying that a shop is located at Gare du Nord is one of the cases. But Jano
notes that this impreciseness isn't that useful. Presumably a more
mathematical spatial predicate might be used based on the geometry of the
shop and the station; e.g.

ex:shop geo:within ex:gareDuNord .

... but this triple would need the geometries of both shop and station to
be available to compute (or evaluate) the relationship.

(I think)

More discussion on the plenary call this evening at 20:00utc.

Hi all,

As far as the Anne Frank house example is concerned, I would be surprised
to see an even-driven fire incident entity being defined samePlaceAs as a
building. Instead, I would say 'ex:fireIncident-56a38 tookPlaceAt <
https://g.co/kg/m/02s5hd>' or from an event perspective
'ex:fireIncident-56a38 involved < <https://g.co/kg/m/02s5hd>
https://g.co/kg/m/02s5hd>' or ''ex:fireIncident-56a38 covered <
https://g.co/kg/m/02s5hd>' (if the space is the key issue here), or  any
other form of modeling the relation between the incidents and places. This
seems way more useful to me than saying that the fire incident is the same
place as the house; after all I want to say that the fire happened there
not that they are the same.


+1.
Just asking…. What about using sameAs for more precise entities, for
example rooms, apartments inside a big building? (*)
For example one could have:
 ex:gareDuNord a :Location.
 ex:ShopInGardeDuNord :samePlaceAs ex:gareDuNord ?

Best,
