The main goal is to generate a namespace file. For example, to generate a namespace for the Human Phenotype Ontology, abbreviated with the prefix hp, the following command can be used:

$ pybel-ols namespace_from_ols hp --encoding "O" --output ~/Desktop/hp.belns

Where --encoding "O" tells it that all terms in this ontology correspond to the pathology/phenotype BEL type.

Alternatively, the '-b' option can be used to specify an alternate OLS instance

$ pybel-ols namespace_from_ols hp --encoding O --output ~/Desktop/hp.belns -b https://localhost/ols
