What is Tawny-OWL

Fully Programmatic Ontology Development
Built on Clojure, the JVM, OWL API and some reasoners!
Provides an R like environment

The Karyotype Ontology

The karyotypes ontology is an extreme example
~1000 classes from one pattern
Very cool, but hard to understand

Literate Programming

A program should be both readable and executable
Weak Form in Javadoc
Neither form (should!) have primacy
Because Tawny-OWL is textual, we can apply the same idea
Tangling

Lenticular Text

We use a new paradigm for text editing to support this
The user gets two views of the same content
One view for working with documentation
One view for working with code
Implemented with the lentic package

Lenticular Text

Lentic Workflow

Lentic is actually generic — can combine any syntaxes
Including things not ontology related
Tawny-OWL does not depend on lentic

Conclusions

Tawny-OWL provides a rich programmatic ontology environment
Literate Ontologies are ontologies which can also generate out rich documentation from a single source.
Lenticular text enables editing of this form of source
Tawny-OWL manual is now being written in this way
As is the Karyotype Ontology
