The P01 Parameter Usage Vocabulary is based on a semantic model. This model uses a defined set of controlled vocabularies (the semantic components). The Facet Search below facilitates you to search for specific existing P01 terms using components for drilling down.
Are you missing specific P01 terms in the vocabulary, then you can compose and submit new terms for review and uptake using the P01 Vocabulary Builder tool.
