The GraphML Schema version 1.0 is located at
http://graphml.graphdrawing.org/xmlns/1.0/graphml-structure.xsd
-> Types
Elements:
-
desc
-
Description: Provides human-readable descriptions for the GraphML
element containing this <desc> as its first child.
Occurence: <key>, <graphml>, <graph>,
<node>, <port>, <edge>, <hyperedge>, and
<endpoint>.
-
locator
-
Description: Graphs and nodes are declared by the elements
<graph> and <node>, respectively. The optional
<locator>-child of these elements point to
their definition. (If there is no <locator>-child
the graphs/nodes are defined by their content).
Occurence: <graph>, and <node>.
-
data
-
Description: In GraphML there may be data-functions attached
to graphs, nodes, ports, edges, hyperedges and
endpoint and to the whole collection of
graphs described by the content of <graphml>.
These functions are declared by <key> elements
(children of <graphml>) and defined by <data>
elements.
Occurence: <graphml>, <graph>, <node>, <port>,
<edge>, <hyperedge>, and <endpoint>.
-
key
-
Description: In GraphML there may be data-functions attached
to graphs, nodes, ports, edges, hyperedges and
endpoint and to the whole collection of
graphs described by the content of <graphml>.
These functions are declared by <key> elements
(children of <graphml>) and defined by <data>
elements.
Occurence: <graphml>.
-
default
-
Description: In GraphML there may be data-functions attached
to graphs, nodes, ports, edges, hyperedges and
endpoint and to the whole collection of
graphs described by the content of <graphml>.
These functions are declared by <key> elements
(children of <graphml>) and defined by <data>
elements.
The (optional) <default> child of <key> gives
the default value for the corresponding function.
Occurence: <key>.
-
graphml
-
Description: <graphml> is the root element of each GraphML
document.
Occurence: root.
-
graph
-
Description: Describes one graph in this document.
Occurence: <graphml>, <node>, <edge>, <hyperedge>.
-
node
-
Description: Describes one node in the <graph>
containing this <node>.
Occurence: <graph>.
-
port
-
Description: Nodes may be structured by ports; thus edges
are not only attached to a node but to a certain
port in this node.
Occurence: <node>, <port>.
-
edge
-
Description: Describes an edge in the <graph> which contains this
<edge>.
Occurence: <graph>.
-
hyperedge
-
Description: While edges describe relations between two nodes,
a hyperedge describes a relation between an arbitrary
number of nodes.
Occurence: <graph>.
-
endpoint
-
Description: The list of <endpoints> within a hyperedge
points to the nodes contained in this hyperedge.
Occurence: <hyperedge>.
