GO Annotation Standard Operating Procedures

This page documents some of the standard operating procedures used by members of the GO Consortium during the process of annotation. Please note that these do not represent the best, or only ways to carry out annotation, but are simply a guide to how some groups currently annotate.

GO Projects

The following areas of biology are the focus of ontology development and annotation in the Gene Ontology Consortium (GOC). Some of these projects are currently underway and we welcome your feedback and contributions. Please reach the GOC using our "Contact us" form.

Biological Process Ontology Guidelines

A biological process is a recognized series of events or molecular functions. A process is a collection of molecular events with a defined beginning and end. Mutant phenotypes often reflect disruptions in biological processes.

General Considerations

Beginning and end

Every process should have a discrete beginning and end, and these should be clearly stated in the process term definition.

GO Annotation Conventions

Annotation Conventions

This page contains guidelines which apply to all annotation methods and are particularly useful for manual literature-based annotation. More information on annotation can be found in the introduction to GO Annotation Policies and Guidelines and the GO Annotation Standard Operating Procedures.
