Introduction to DGML[edit]
Here is what a simple directed graph with three nodes and two links between them looks like
<?xml version="1.0" encoding="utf-8"?> <DirectedGraph xmlns="http://schemas.microsoft.com/vs/2009/dgml"> <Nodes> <Node Id="a" Label="a" Size="10" /> <Node Id="b" Background="#FF008080" Label="b" /> <Node Id="c" Label="c" Start="2010-06-10" /> </Nodes> <Links> <Link Source="a" Target="b" /> <Link Source="a" Target="c" /> </Links> <Properties> <Property Id="Background" Label="Background" DataType="Brush" /> <Property Id="Label" Label="Label" DataType="String" /> <Property Id="Size" DataType="String" /> <Property Id="Start" DataType="DateTime" /> </Properties> </DirectedGraph> which looks like this:
The complete XSD schema for DGML is available at [1]. DGML not only allows describing nodes and links in a graph, but also annotating those nodes and links with any user defined property and/or category.
