GPML2017

We are currently working intensively on an updated GPML schema with lots of improvements and new features.

---

Summary

• XML element names in upper camel case (e.g. DataNode)
• XML attribute names in lower camel case (e.g. fillColor, dataSource)
• Documentation of the schema definitions included in the XSD file using xsd:annotation / xsd:documentation
• Default definitions supported by PathVisio and WikiPathways included in schema definition (e.g. type attribute for DataNode)
• Graphics attributes (e.g. centerX, centerY, width) are now included in the main XML element
• Major restructuring of citations and ontology tags (removing dependency on BioPAX)

Attribute renaming

• graphId to elementID
• version in Pathway element to revision
