Hi all,
I'm wondering if someone can help me check my understanding of how ARQ
evaluates the following DAWG test query. Output below using Fuseki 1.1.0 ( How
do I check which version of ARQ is in this version of Fuseki?). I'm wondering
if in the first un-optimized algebra form, this amounts

Yeah, that's pretty close. I originally posted this thread, cause I found
myself looking at

All the answers there were close, but just slightly off. I've
posted what I now think is the
Why does this query:
PREFIX afn:http://jena.hpl.hp.com/ARQ/function#
SELECT ?s2
WHERE
{
BIND(http://example.org/book/book2/sadfju/62eja AS ?uri)
BIND( afn:localname(?uri) AS ?s2 )
}
give this answer:
-
| s2|
=
| eja |
-
shouldn't it be: 62eja ?

Hi,
I've been trying to figure out an issue with addition of strings in
SPARQL. According to the DAWG evaluation test at:

and so a workaround after Java 6 support is dropped will be to build from
source yourself.
I don't think that once support is dropped, you can build from source for
long. If Jena project makes use of a new language feature, or library included
in Java 7 or Java 8, running Jena with
correction: building from source, with Java 6. I'm guessing byte code
compatibility of the different versions is the same.

I discovered DatasetAssemblerVocab which helped me realize I was using a wrong

so it is accessing the default graph at rdfs:label -- no matches, no
results.
Remove the tdb:unionDefaultGraph - also try with out the rdfs:label to
show the index does return something.
