Orphanet made available twice a year :
- ORDO to provide a structured vocabulary for rare diseases, capturing relationships between diseases, genes and other relevant features, forming a useful resource for the computational analysis of rare diseases.
- HOOM, a module that qualifies the annotation between a rare disease and phenotypic abnormalities according to a frequency and by integrating the notion of diagnostic criterion.
- SPARQL endpoints for ORDO and HOOM
