What is XGMML?

[http://www.cs.rpi.edu/~puninj/XGMML/ XGMML] is an XML version of [http://infosun.fmi.uni-passau.de/Graphlet/GML/ GML].

XGMML in Cytoscape

In the future releases, Cytoscape's standard format for saving graph layout will be XGMML. Users can save graph topology AND attributes in the same file.

XML Schema

The code to manipulate data element in XML file will be generated by data binding package, called [http://java.sun.com/webservices/jaxb/ Java Architecture for XML Binding (JAXB)]. JAXB automatically generate JAVA code based on XML Schema. XML schema for XGMML is available [http://www.cs.rpi.edu/~puninj/XGMML/xgmml.xsd here].

Metanode and XGMML

In Cytoscape v2.3, a new concept called Metanode will be introduced. In XGMML, metanode is a node which has a subgraph containing nodes and edges. For more information, please read ["Metanode In XGMML"] section.

File Format

Network file in XGMML has the following information:

• Interactions (Nodes/Edges)
• Attributes (annotation for nodes/edges)
• Graphical representation of nodes and edges
• Network meta-info in RDF
  • This is a general information for the network. Generic information like network name, date modified, etc. will be inserted here. The data format used for network meta-information is RDF (Resource Description Framework). The supported attributes are taken from Dublin Core Metadata Element Set (DCMES):
    • Title
    • Creator
    • Subject
    • Description
    • Publisher
    • Contributor
    • Date
    • Type
    • Format
    • Identifier
    • Source
    • Language
    • Relation
    • Coverage
    • Rights

  • Although internal data structure will support all of the above, GUI (Network Metadata Editor) supports subset of the elemets. For more information about DCMES, please visit [http://dublincore.org/documents/dces/ here].
