Thanks again Morsey. Greatly appreciate your help!
The encoding issue explains several of the cases that I have seen. However, I
saw other cases, where dbpedia ontology properties are missing in the triples
returned from live.dbpedia, where it may not be due to the uri encoding issue.
For example,
http://live.dbpedia.org/data/Spanking_the_Monkey.ntriples
vs
http://dbpedia.org/data/Spanking_the_Monkey.ntriples
In the triples returned from live.dbpedia.org, the properties -
<http://dbpedia.org/ontology/musicComposer>,
<http://dbpedia.org/ontology/director> and few other ontology properties are
missing. These ontology properties are, however, returned from dbpedia.org. I
am wondering whether the missing triples are not existing in the live.dbpedia
triple store (or) if they are getting dropped during the request.
Another example is
http://live.dbpedia.org/data/Silver_Linings_Playbook.ntriples. In this case,
both the <http://dbpedia.org/property/director> and
<http://dbpedia.org/ontology/director> are missing. Is there any known issue
that may be causing this?
ThanksArun

Hi,
Frequently, I am finding that the set of triples
returned by live.dbpedia.org for a resource would be missing
some properties, when compared
to the triples returned by dbpedia.org.
For example, compare
http://live.dbpedia.org/data/Titanic_(1997_film).ntriples
vs
http://dbpedia.org/data/Titanic_(1997_film).ntriples
The triples returned from live.dbpedia.org for
Titanic do not have any of the ontology properties for
director, writer, musicComposer etc, whereas the triples
returned from dbpedia.org (using the above url) do have
these properties for director, writer, musicComposer
There is an encoding issue here, and we will try to fix it ASAP.
Is it expected that live.dbpedia.org wouldn't have
all the properties for a resource, although they are
available from dbpedia.org?
The data in DBpedia-Live is complete and if you use the following
query, you will get the complete data about "Titanic":
http://live.dbpedia.org/sparql/?default-graph-uri=http%3A%2F%2Fdbpedia.org&query=CONSTRUCT+{%3Fs+%3Fp+%3Fo}+WHERE+{+%3Fs+%3Fp+%3Fo.+FILTER%28%3Fs+%3D+%3Chttp%3A%2F%2Fdbpedia.org%2Fresource%2FTitanic_%25281997_film%2529%3E%29+}&should-sponge=&format=text%2Fplain&timeout=0&debug=on
Thanks
