[Bigdata-developers] How to setup the defaultGraph property when using the bulk loader?

[Daniel H. <da...@de...>]

Hi,

I am trying to load quads into Blazegraph 2.1.0 using the bulk loader.

java -cp blazegraph.jar com.bigdata.rdf.store.DataLoader 
config.properties data.nq

The documentation [1] said that I have to set the defaultGraph property when
loading quads (because some statements are triples). Thus, I added
the line

defaultGraph=http://example.org

to the properties file. However, it continues producing a context error. 
I think
that I'm not doing this properly. So, how can I specify the defaultGraph?

(I first asked in Stackoverflow [2]. I guess that this mailing list has more
readers.)

Daniel,

I believe you need < > around the URI:  <http://example.org>.

Let us know how it goes.

Thanks,  Brad

Brad, I tried with the line

defaultGraph=<http://example.org>

in the properties file, but I got the same error: "context not bound".

Thanks,
Daniel

Daniel,

Can you post your configuration file for the bulk loader?

Thanks, --Brad

Brad, I put the steps and files to reproduce my problem in:

Thanks,
Daniel

[Michael S. <ms...@me...>]

Dear Daniel,

afaik you need to pass the defaultGraph parameter as a command line argument to the DataLoader call (rather than providing it inside the properties file). Could you please try that?

Best,
Michael

I am not sure where I have to put this option, so I tried with all 
possible ways:

$ java -cp blazegraph.jar com.bigdata.rdf.store.DataLoader 
-DdefaultGraph=http://example.org server.properties data.nq
Unknown argument: -DdefaultGraph=http://example.org
usage: [-closure][-verbose][-durableQueues][-namespace namespace] 
propertyFile (fileOrDir)+

$ java -cp blazegraph.jar -DdefaultGraph=http://example.org 
com.bigdata.rdf.store.DataLoader server.properties data.nq
=> context error

$ java -DdefaultGraph=http://example.org -cp blazegraph.jar 
com.bigdata.rdf.store.DataLoader -DdefaultGraph=http://example.org 
server.properties data.nq
=> context error

Thanks,
Daniel

Hi Daniel,

please try

It works! The usage message did not include the option -defaultGraph. I 
could not have solved this without your help.

Thanks,
Daniel

Glad I could help — you’re right, I’ve created https://jira.blazegraph.com/browse/BLZG-1886 <https://jira.blazegraph.com/browse/BLZG-1886> as a follow-up to improve the usage message with all available options.

Best,
Michael
