“Payao” aims to enable a community to work on the same models simultaneously, insert tags to the specific parts of the model, exchange comments, record the discussions and eventually update the models accurately and concurrently.
“Payao” reads the models in Systems Biology Markup Language (http://sbml.org) format, displays them with CellDesigner, a process diagram editor (http://celldesigner.org) , and provides an interface for adding tags and comments to the models for the community members.
