The "coordinate" property cannot be rendered using a geographically-specific format for sessions & events.(TheSessionDB)

[candlecao]

Such as:
Point(-34.56250000 -58.45833206)(longitude and latitude).

If we can render this, may be in the future, we can realize some query based on geographical information system.

ChatGPT gave this format:

@prefix ns1: <http://www.wikidata.org/prop/direct/> .
@prefix geo: <http://www.w3.org/2003/01/geo/wgs84_pos#> .

<https://thesession.org/events/1> ns1:P625 [ 
    geo:lat "55.85637283"^^xsd:float ;
    geo:long "-4.25716591"^^xsd:float 
] .

<https://thesession.org/events/10> ns1:P625 [ 
    geo:lat "55.20029831"^^xsd:float ;
    geo:long "-6.25256252"^^xsd:float 
] .

Please use this format:
such as

@prefix geo: <http://www.opengis.net/ont/geosparql#> .
@prefix ns1: <http://www.wikidata.org/prop/direct/> .

<https://thesession.org/events/754> ns1:P625 "POINT(54.25597000 -5.94771004)"^^geo:wktLiteral .

instead of

@prefix ns1: <http://www.wikidata.org/prop/direct/> .
@prefix wgs: <https://www.w3.org/2003/01/geo/wgs84_pos#> .
<https://thesession.org/events/754> ns1:P625 "(54.25597000 -5.94771004)"^^wgs:Point .

I used regular expression in Visual Studio Code temporarily:
Find: (P625 "Point\([^)]+\)")
Replace: $1^^geo:wktLiteral

[candlecao]

However, after the Find-Replace, I found more mistakes in the values of wdt:P625.
For example,

PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
PREFIX wdt: <http://www.wikidata.org/prop/direct/>
SELECT distinct (DATATYPE(?value) AS ?datatype)
WHERE {
  ?subject wdt:P625 ?value .
  BIND(wdt:P625 AS ?property)
}

We may talk over it. @Yueqiao12Zhang

[candlecao]

--some mistakes such as this. So I am concerned if there is something wrong with your code.

[candlecao]

In our original data there are events which have no coordinate:

[fujinaga]

If there's no location information in the database, there's nothing we can do.

[candlecao]

Eventually, we can use this format to render the coordinate info:
eg:

@prefix geo: <http://www.opengis.net/ont/geosparql#> .
@prefix wdt: <http://www.wikidata.org/prop/direct/> .
<https://thesession.org/events/1> wdt:P625 "POINT(55.85637283 -4.25716591)"^^geo:wktLiteral .
