Quick Start

Sandbox

To understand how G2GML works quickly, please visit the sandbox.

Some usage samples are provided. Notice that in order to use the sandbox effectively, knowledge about RDF and SPARQL are strongly recommended.

Command Line Usage

Installation

Set an alias to run a docker container:

$ alias g2g='docker run --rm -v $PWD:/work g2glab/g2g:0.3.5 g2g'

Check if it works:

$ g2g --help

Execution

Download example turtle file:

$ wget https://raw.githubusercontent.com/g2glab/g2g/master/examples/mini-05/mini-05.ttl

mini-05.ttl

@prefix : <http://example.org/> .
:person1 a :Person .
:person2 a :Person .
[] a :Follow ;
   :follower :person1 ;
   :followed :person2 ;
   :since 2017 .

Download example g2g file:

$ wget https://raw.githubusercontent.com/g2glab/g2g/master/examples/mini-05/mini-05.g2g

mini-05.g2g

PREFIX : <http://example.org/>

(p:person)
    ?p a :Person .

(p1:person)-[:follows {since:s}]->(p2:person)
    ?f :follower ?p1 ;
       :followed ?p2 ;
       :since ?s .

Run (mapping against RDF data file):

$ g2g mini-05.g2g mini-05.ttl

Check the output file:

$ more output/mini-05/mini-05.pg

mini-05.pg

"http://example.org/person1" :person
"http://example.org/person2" :person
"http://example.org/person1" -> "http://example.org/person2" :follows since:2017
