Koza and Koza-Hub for born-interoperable knowledge graph generation using KGX

Abstract: Knowledge graph construction has become an essential domain for the future of biomedical research. But current approaches demand a high amount of redundant labor. These redundancies are the result of the lack of data standards and "knowledge-graph ready" data from sources. Using the KGX standard, we aim to solve these issues. Herein we introduce Koza and the Koza-Hub, a Python software package which streamlines ingesting raw biomedical information into the KGX format, and an associated set of conversion processes for thirty gold standard biomedical data sources. Our approach is to turn knowledge graph ingests into a set of primitive operations, provide configuration through YAML files, and enforce compliance with the chosen data schema.
