RDF Dump

[Jasper Koehorst]

I tried to perform a graph dump to RDF files but somehow this either does not work or I am doing something odd...

I have this command:

jasperk@ssb2:~$ /stardog/stardog/stardog-2.2.1/bin/stardog data export -g ALL -s -p password -u user snarl://127.0.0.1:4567/ncbi /usb/ncbi.trig

Exported 1,039,766,536 statements from ncbi as TriG in 2.806 h

but when I ask the size of /usb/ncbi.trig it gives me 0 bytes.

So where did it put the data?

[Mike Grove]

It's in /usb/ncbi.trig on the server where Stardog is running.

Cheers,

Mike

That is the entire problem:

-rw-rw-r--    1 jasperk jasperk      0 Sep 10 13:31

It contains 0 bytes...

For example:

stardog data export --format TURTLE -p ssbdata -u admin snarl://127.0.0.1:4567/ncbi

or TRIG

gives

@prefix owl: <http://www.w3.org/2002/07/owl#> .

@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .

@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .

@prefix stardog: <tag:stardog:api:> .

@prefix xml: <http://www.w3.org/XML/1998/namespace> .

@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .

and thats it while...

stardog data export --format TURTLE --named-graph http://ssb.wur.nl/ncbi -p ssbdata -u admin snarl://127.0.0.1:4567/ncbi

shows nothing

and

stardog data export --format TURTLE --named-graph http://ssb.wur.nl/ncbi -p ssbdata -u admin snarl://127.0.0.1:4567/ncbi /usb/ncbi_data

creates an empty file.

When I look at IOTOP it shows that it is writing at full speed but after 2 hours it says that it finished and create ±1 billion triples but the file is empty....

Actually, it should be in .exports in your STARDOG_HOME directory.  You should actually get an error on the CLI specifying -s/--server-side and a file argument.

Thanks it might be useful to put that with big letters in the manual ;)

I found the files! (Many of them as I tried all kinds a lot…) Time to clean them up now.

It's mentioned in the manpage [1]
