Installed and sucessfully running the latest_core collection but no results returned for SPARQL queries or pages don't show correctly
Here is a sparql for returning entries related to Steve Jobs' page :
SELECT ?uri ?sameAs WHERE { ?uri dbo:wikiPageID 7412236 . ?uri owl:sameAs ?sameAs }
It returns values on live dbpedia but when I run through virtuoso on my machine nothing is returned. Also any dbpedia page(Even non-existing ones) have only on statement which is sameAs, pointing to live dbpedia. as below:
What should I do to make it work on my local machine correctly?
I recently installed this with the docker-compose quickstart and it seems to be loading very similarly to the "live" dbpedia page for me:
Can you clarify when you say "installed and successfully running" about how long the download/load process took and what message you saw? And you are definitely using the latest_core URI and not the https://databus.dbpedia.org/dbpedia/collections/virtuoso-sparql-endpoint-quickstart-preview ?
It took considerable time to download the data when I used latest_core. Similarly, when I use the started package to test and view the page for Berlin as suggested in the main github page, it shows a similar page to the above :
I'm running these on a VirtualBox Ubuntu machine. And here is the output of the command :
Hi, I also see differences between the public dbpedia endpoint and my local instance (I'm running the docker with the latest core collection: https://databus.dbpedia.org/dbpedia/collections/latest-core). Otherwise, I'm running dockers as they are in the repo (except for adjusting buffer sizes). The query I'm using for testing is:
SELECT DISTINCT ?child WHERE {
<http://dbpedia.org/resource/Calcium> dbo:wikiPageWikiLink ?child .}
which returns results on the public endpoint but not on my local endpoint.
The endpoint is running locally without any problem. It just seems like some data is missing. That said, I do see:
*** Error S2801: [Virtuoso Driver]CL033: Connect failed to store:1111 = store:1111.
when running docker-compose up store load
Could that be the reason for the missing data? If, what could be the issue? Thanks!
I have exactly the same problem (I only get the sameAs properties, nothing else), have you found a solution yet?
