ChEBI is an ontology of chemical entities of biological interest. It includes a structure-based and a role-based classification of chemical entities including molecules, ions and salts. This poster showcases recent developments and forthcoming enhancements to the ontology, focusing on modular extensions of the content. These extensions are being developed in support of error detection and consistency checking and to improve the capability for automated reasoning about the biological context of chemicals.
