Thanks Kingsley! Very helpful, as always :) -- nice map too!

Re: dbpedia, do you generally ensure either wgs84 or
dbpedia.org/property/{lat,long}Degrees, or should such a mapping rule
exist?

We need to make a mapping rule, then add it to the default list. Once in place, via /FCT or /SPARQL, you can then optionally invoke inference context that drives your queries.

OK, got it down to:

select ?uri, ( ?sc * 3e-1 ) as ?sc, ?label, ( sql:rnk_scale (
<LONG::IRI_RANK>    ( ?uri ) ) ) as ?rank where  {
    ?uri<http://www.w3.org/2000/01/rdf-schema#label>    ?label .
    ?uri<http://dbpedia.org/property/latDegrees>    ?posLat .
    ?label bif:contains '( sand and dunes )' option ( score ?sc ) .
    FILTER( lang(?label) = "en" ) .
} order by desc ( ?sc * 3e-1 + sql:rnk_scale (<LONG::IRI_RANK>    ( ?uri ) )
)

but there is only 1 result!?

Wrong endpoint? Is inference re. latDegrees == wgs84#lat disabled?
Such a rule wouldn't be on by default. We could add this to the
pre-configured list of rules that you can then select via /FCT.

For now, see:

I dropped these in a hurry as I saw this pass by :-)

Hello, I copied a query /fct running fine for sand dunes:

select ?s1, ( ?sc * 3e-1 ) as ?sc, ?o1, ( sql:rnk_scale (
<LONG::IRI_RANK>    ( ?s1 ) ) ) as ?rank where  {
    ?s1 ?s1textp ?o1 .
    ?o1 bif:contains '( sand and dunes )' option ( score ?sc ) .
} order by desc ( ?sc * 3e-1 + sql:rnk_scale (<LONG::IRI_RANK>    ( ?s1
) ) ) limit 20 offset 0

It runs fine. After adding just 1 constraint, that these are locations
(have longitude+latitude):
    ?o1<http://dbpedia.org/property/latDegrees>    ?posLat .

Virtuoso 42000 Error The estimated execution time 751545 (sec) exceeds
the limit of 1500 (sec).

I am trying to build a query that lets me search for linked data
places I can put on a map. Sorry I'm not more familiar with Virtuoso
and thanks for any suggestions...

Best regards,
