Load rdf data into neo4j

[Sun Yuhan]

I am trying to load wikidata into neo4j which I download from this link:

https://dumps.wikimedia.org/wikidatawiki/entities/20180222/

After unzipping, the total size is about 300GB. How can I efficiently load that into neo4j? Any suggestion?

Thanks,

[Michael Hunger]

Perhaps starting with a subset makes sense?

Jesus did you ever import wikidata?

Did you see the neosemantics library by my colleague Jesus Barrasa which supports loading RDF into Neo4j: https://github.com/jbarrasa/neosemantics

Explained a bit here: https://jbarrasa.com/2016/06/07/importing-rdf-data-into-neo4j/

For wikidata I also found these:

Cheers, Michael

I have tried neosemantics. I use a sample data of wikidata to test the loading function. The query I am running is:

CALL semantics.liteOntoImport('/home/yuhansun/Documents/GeoReachHop/test/slice_100000.nt','RDF/XML')

After running that, it shows 

Not sure where I am wrong in doing this.

One more question. Is this faster than using batchinserter?

Hi, the semantics.liteOntoImport is a limited importer for RDFS/OWL ontologies (it only takes classes, properties, domains and ranges if I remember correctly).

I think what you're trying is to load some generic RDF so probably you should try the semantics.importRDF procedure instead.

Hope this helps.
