This tutorial gives an introduction to using WebProtégé for curating PGx recommendations.
A Protégé is developed by Stanford University. And general tutorial -puropose tutorials (for the Desktop Protégé (desktop and web-versionWebProtégé) can be found at the [https://protegewiki.stanford.edu/wiki/Main_Page Stanford Protégé Wiki].
The best Protégé tool for looking at OWL semantics is the desktop version of Protégé, which is a visual front-end to the OWLAPI.
[[File:Webprotege main screen.png|thumb|Default ''Classes'' tab with views ''Class Hierarchy'', ''Class'', ''Comments'' and ''Project Feed'' is shown when opening a new OWL file or creating a new OWL ontology]]
When opening an OUS adapted PharmGKB OWL file PGx guideline in WebProtégé for the first time, we are presented to the ''Classes'' tab, containing four so-called views (frames)
* ''Class Hierarchy'' (a tree of all class entities of this ontology)
* ''Class'' (for description and editing of each class entity)
==Using WebProtégé for curation of PGx recommendations==
We suppose that the user has modified the ''Classes'' tab as explained above. We will use the drug voriconazole as an example. We have downloaded the CPIC guideline from the PharmGKB API and converted the PharmGKB JSON-LD file to the OWL format that can be edited in WebProtégé. 
===Curation of the functional status of star alleles===
[[File:WebProtege user interface func status.png|thumb|Inspection of the gene function element ''Voriconazole CYP2C19: Decreased function'' in the ''Class Hierarchy'' shows which star alleles that have this functional status]]
Finally, the WebProtégé can be used for writing the actual prose of the recommendations. For instance, if the curator wants to translate the CPIC recommendations into another language, in the ''Class'' view, she can enter a property ''Recommendations'', a recommendation text and tagging it with the appropriate language.

===Downloading the guideline in OWL format===
[[File:WebProtege download owl ontology.png|thumb|A new revision of the OWL PGx guideline can be downloded from the ''History'' tab]]
 
One way to download a new revision of the guideline, is to go to the ''History'' tab, click on the revision number that you want to download, and download this as a .zip-file.
