Dataset connectivity. Querying across datasets in Petagraph requires connecting relationships. A hallmark feature of Petagraph is the rich set of ontological and biomedical mapping data sources that connects phenotypic and genomic data together across human and mouse models. This figure only captures a select set of datasets and relationships in Petagraph. The log10 relationship count between Petagraph-specific datasets reveals which of these datasets have direct Concept to Concept relationships through one-hop relationships, however many of these datasets are linked together through one or more intermediary datasets. For example, HGNC establishes a connection to MP through the HPO dataset (HGNC to HPO to MP).
