Protein Application Ontology (P-PRO)

Currently the world is facing a large population growth and the effects of climate change, which pose challenges regarding food security, including the need for adequate consumption of proteins. More sustainable protein sources, such as legumes, aquatic crops and insects will have to be used. There is an increasing need for expressing information on proteins and their sources and determining what processes are involved in the production and use of proteins. A number of ontologies already exist to support specific aspects of protein research. In addition, the protein application ontology 'P-PRO' aims to enable and enhance data sharing between the different parties involved in protein research and production.In this report, we discuss the structure of the P-PRO ontology and how it is embedded in the web of ontologies regarding proteins. P-PRO includes information from the fields of protein technology and human nutrition and health research. There is a link between P-PRO and the Ontology of Units of Measures, OM; the sensor ontologySOSA, several anatomical ontologies and the NCBI Taxon database. P-PRO will be available as an open-source ontology. If P-PRO is adopted widely it can enrich standards that are already establishe
