---------------------------------
Summary: Enable Multi Var Geo Functions
Key: RYA-323
URL: https://issues.apache.org/jira/browse/RYA-323
Project: Rya
Issue Type: Improvement
Components: sail
Reporter: Aaron Mihalik
Assignee: Aaron Mihalik
Currently, all Rya GeoSPARQL functions must have at least one parameter as a
constant, eg:
{code}
?point geo:asWKT ?wkt .
FILTER(geof:sfWithin(?wkt, "POLYGON(( ... ))"^^geo:wktLiteral))
{code}
however, there is no good reason for this. In fact, we will later want to
support functions that take in two variables. For instance, a previous set of
statement patterns will resolve a wkt, then I want to pass that wkt value into
the function, eg:
{code}
<myEntity> <hasLocation> ?point .
?point geo:asWKT ?wkt1 .
?point geo:asWKT ?wkt2 .
FILTER(geof:near(?wkt2, ?wkt1))
{code}
