Can it support OWL 2 QL ontologies? or can it be extended to support OWL 2 QL ontologies?

DataProperty should be added to DL-Programs Parser, e.g.

DL[...,Q](X, "abc"^^xsd:string)

I have drew 3, dlv2 (binary) and i am trying to execute graph.owl and graph.dlp from sample_data folder.

drew -el -ontology graph.owl -dlp graph.dlp -dlv /home/haya/dlv-2.1.0-linux-x86

But I am getting DLV Error, exitValue=110

/usr/dlv-2.1.0-linux-x86: invalid option -- 'p', , Generic error: This option is not supported., DLV Error, exitValue=110]

No matter which example I execute I get this error. Why am I getting this error?

Thankyou!

combine Horn-SHIQ rewriting in Clipper into DReW

compute only the first answer set or at most a given number of answer sets

In the currently implementation, drew encodes every constant to "o\d*" in the generated DLV output. This has problem with arithmetic operation.

e.g.

poss_dist(X, Y, 1) :- metro_next(Line, X, Y).
poss_dist(X, Y, N1) :- poss_dist(X, Z, N), metro_next(Line, Z, Y), N1 = N + 1, #int(N1), #int(N).
->
poss_dist(X, Y, "o26398") :- metro_next(Line, X, Y).
poss_dist(X, Y, N1) :- poss_dist(X, Z, N), metro_next(Line, Z, Y), N1 = N + 1, #int(N1), #int(N).
