GPML
Graphical Pathway Markup Language
Release planning, ongoing developments and feature requests
Directory "test" contains a variety of GPML files to serve as an acid test for GPML parsing and handling libraries (inspired by csv-spectrum).
The GPML2013a-fuller schema was never used in PathVisio-Java, but it more accurately and fully reflects the GPML used from 2013 to 2017 than does the GPML2013a schema. Both the GPML2013a and GPML2013a-fuller schemas attempt to describe the exact same GPML.
