A practical introduction to OBO-Edit2

Tutorial by David Osumi-Sustherland (FlyBase)

Date: ???

OBO-Edit2, the new version of the popular ontology editing tool, has many powerful new tools for ontology analysis and construction. This tutorial will provide an introduction to the use of OBO-Edit2 to build and maintain OBO ontologies with special emphasis on working with necessary and sufficient definitions.

The following topics will be covered

OBO basics

The type/instance distinction [2]

Theory of OBO relations [2]

Necessary and sufficient definitions

Avoiding tangled hierarchies [1]

OBO-Edit2 basics

Basic editing with the tree editor and the parent editor

Basic searching, filtering and rendering

Necessary and sufficient definitions and use of the reasoner

Declaring disjunction and finding contradictions

OBO-Edit2 advanced:

Advanced searching and rendering

Using renders to track editing progress

Selective importation of foreign terms

Tracking redundancy

Graphing with OBO-Edit

Preparing OBO files for release:

Verification

Making implied links hard and stripping redundancy.
