View source for GraphML export

Wandora is capable to export Topic Map as [http://graphml.graphdrawing.org/ GraphML] formatted graph. Exported GraphML serialization can be later used with external graph applications such as [http://www.yworks.com/en/products_yed_about.html Yed]. GraphML export starts with '''File > Export > GraphML export''' option.

== Export details ==

* Each topic is exported as a graph node.
* Each binary association is converted to an edge between player nodes. Edge's label is association type.
* If association has more than two players, an extra intermediate node is created and each player is linked to the intermediate node with an edge.
* If association has only one (or none) player, it is not exported.
* Each occurrence is exported as a node and an edge between occurrence text and topic node.
* Subjects, scopes, association roles, and variant names are not exported.

Exported nodes and edges don't include coordinates.

== Configuring the export ==

To configure the GraphML export hold CTRL key down while starting the export. Configuration dialog allows you to select whether or not to

* Export class-instance relations as edges.
* Export occurrences as edges.
* Export n-ary (n>2) associations as edges.
* Export directed or undirected graph.
