Hi Holger ,
Thanks for pointing me in the right direction. The problem was caused by
missing out an argument the ,"#" in the query below, although it was
accepted as valid without it.
Whist on the subject of functions , if I could take the liberty of asking
you to clarify what is the difference between spif:buildUri and
smf:buildUri, I currently use smf:buildUri, I think I got the reference
from one of the tutorials or the scripts file, but looking at the help
pages function is listed with spif as the qname
Thanks again John
CONSTRUCT {
?this coreModel:source ?uri .
}
WHERE {
BIND (afn:namespace(?this) AS ?nameSpace) .
BIND (fn:substring(?nameSpace, 1, 42) AS ?subString) .
BIND (fn:substring(?nameSpace, 44) AS ?subString1) .
BIND (fn:substring(?subString1, 1, spif:lastIndexOf(?subString1, "#"))
AS ?localName) .
BIND (?localName AS ?boundLocalName) .
BIND (smf:buildURI("{?subString}#{?boundLocalName}") AS ?uri) .
}
