How to store and query RDF data in Solr? Let’s do that in 2 minutes / 5 steps!
Step #1: What we need?
- A shell (in case you are on the dark side of the moon, all steps can be easily done in Eclipse or whatever IDE)
- Java 7 or higher
- Apache Maven (3.x)
- git
Step #2: Checkout SolRDF
Open a shell and type the following:
> cd /tmp
> git clone https://github.com/agazzarini/SolRDF.git solrdf-download
> cd solrdf-download/solrdf
> mvn clean install
> cd solrdf-integration-tests
> mvn clean package cargo:run
Step #3: Build and Run SolRDF
The very first time you run this command a lot of things will be downloaded, Solr included. At the end you should see something like this:
[INFO] Jetty 7.6.15.v20140411 Embedded started on port [8080]
[INFO] Press Ctrl-C to stop the container...
Congrats! SolRDF is up and running!
Step #4: Add Some Data
Open another shell and type the following:
> curl -v http://localhost:8080/solr/store/update/bulk?commit=true \
-H "Content-Type: application/n-triples" \
--data-binary @/tmp/solrdf-download/solrdf/src/test/resources/sample_data/bsbm-generated-dataset.nt
Wait a moment and…ok! You’ve added (about) 5000 triples!
Step #5: Query
> cd solrdf-download/solrdf
> mvn clean install
> cd solrdf-integration-tests
> mvn clean package cargo:run
Open another shell and type the following:
Et voilà!
