+## Integration with EMMO
+
+The Electrochemistry Domain Ontology is an official domain on the EMMO. It consists of two files `electrochemistry.ttl` and `electrochemicalquantities.ttl`. The physical quantities related to the electrochemistry domain are included in `electrochemicalquantities.ttl` file, which is encapsulated to allow it to be imported by other EMMO domains without needing to import the entire ontology. The electrochemistry domain also imports the [Chemical Substance Domain Ontology](https://github.com/emmo-repo/domain-chemical-substance) from EMMO to support material annotations in electrochemical (meta)data.

 ## Obtaining the ontology
 
 The correct path to the inferred verion `emmo-inferred` is specified in the catalog file, [`catalog-v001.xml`](catalog-v001.xml).
