Hi Thad,
"Assignment" can be done with CONSTRUCT, so something like this would work
to split a name into two parts:
PREFIX ex: <http://example.org#>
CONSTRUCT {
?human ex:hasfirstName ?first.
?human ex:hasSecondName ?second
} WHERE
{
?human wdt:P31 wd:Q5; rdfs:label ?label .
BIND (STRBEFORE(?label, " ") AS ?first) .
BIND (STRAFTER(?label, " ") AS ?second) .
FILTER (lang(?label)= "en") .
}
