GraphML format

From TrustLet, a free, collaborative project for collecting and analyzing information about trust metrics.

GraphML is a file format for graphs. It consists of a language core to describe the structural properties of a graph and a flexible extension mechanism to add application-specific data.

More information at the official GraphML homepage.

[edit] An example

Here is how a simple undirected graph with 2 nodes and one edge between them looks like:


<?xml version="1.0" encoding="UTF-8"?>
<graphml xmlns="http://graphml.graphdrawing.org/xmlns"  
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://graphml.graphdrawing.org/xmlns
     http://graphml.graphdrawing.org/xmlns/1.0/graphml.xsd">
  <graph id="G" edgedefault="undirected">
    <node id="n0"/>
    <node id="n1"/>
    <edge source="n0" target="n1"/>
  </graph>
</graphml>
