proloGraph

A demo for a REST server developed in prolog reading facts from a CSV file

Usage

Install SWI Prolog, with Linux Debian/Ubuntu just run

apt-get install swi-prolog

Clone my git repository

git clone https://github.com/matteoredaelli/proloGraph
cd proloGraph
mv graph-edges.csv.sample graph-edges.csv

Run the server with

swipl webserver.pl --port=8888

and open the followsing url with your browser

http://myserver:8888/edges_by_name?name=matteo

The result will be

{ "edges": [ { "from": {"name":"matteo"}, "to": {"name":"ele"}, "rel":"follows" }, { "from": {"name":"matteo"}, "to": {"name":"italy"}, "rel":"lives_in" }, { "from": {"name":"matteo"}, "to": {"name":"gabriele"}, "rel":"follows" }, { "from": {"name":"ele"}, "to": {"name":"matteo"}, "rel":"follows" } ] }

And

http://myserver:8888/edges_by_relation?relation=follows

{ "edges": [ { "from": {"name":"matteo"}, "to": {"name":"ele"}, "rel":"follows" }, { "from": {"name":"matteo"}, "to": {"name":"gabriele"}, "rel":"follows" }, { "from": {"name":"ele"}, "to": {"name":"gabriele"}, "rel":"follows" }, { "from": {"name":"ele"}, "to": {"name":"matteo"}, "rel":"follows" } ] }
