Mondo is the disease ontology for the Monarch Initiative, which is an NIH supported project that integrates, aligns, and re-distributes cross-species gene, genotype, variant, disease, and phenotype data. The Monarch Browser allows users to browse not only human diseases but to see their links to other organisms, genes, phenotypes, and pathways, which may be of special interest to translational researchers.

Mondo is co-developed with HPO, to ensure interoperability and alignment between the two ontologies and create a more holistic semantic disease resource. A subset of HPO classes are imported into Mondo. HPO terms are used in the logical definitions for the disease terms, where applicable. For example, MONDO:0003337 ‘acute hemorrhagic encephalitis’ is computationally defined as encephalitis and ('disease has feature' some 'Abnormal bleeding') (Abnormal bleeding is an HPO term, HP:0001892).

Why do we need Mondo?

Please see our blog post that describes why we created Mondo.

Does the definition of ‘equivalent-class’ mapping require that the Mondo/Other relationship is strictly 1:1?

The semantics of owl equivalentClass are such that all concepts are strictly identical in meaning. This always translates to a 1:1 mapping, except when we do a ‘proxy merge’ - we decide that two concepts in an external resource mean the same thing. This is rare, and the numbers usually come down as we work with the upstream to resolve this. See ticket.
