Thank you so much for your interest in GOA TOOLs and for taking your time to write us.

I just added a Jupyter notebook to explain how to access the optional attribute, "def" (aka definition or defn).

https://github.com/tanghaibao/goatools/blob/main/notebooks/Optional_attribute_definition.ipynb

Please let us know if the new notebook answers your question adequately.

Thank you so much for this excellent question, which will surely benefit all of the researchers who use GOA TOOLs in their work
