    * [RDF/OWL format](./ontology/rdf/README.md)
-* [Building Configuration](./ontology/docs/building_config.md) which contains a mapping between the ontology and the "raw" data. Building Config is the Assertion Box.

-  * [Explorer](./tools/explorer/README.md) allows users to explorer the ontology types and their associated fields.
-  * [Yaml Validator](./tools/validators/ontology_validator/README.md) which allows to validate the yaml ontology upon a change or an extension.
-  * [RDF/OWL Generator](./tools/rdf_generator/README.md) which allows to generate an RDF version from the yaml ontology files.

+* Tools that enable the following:
+  * [**ABEL**](./tools/abel/README.md)**:** facilitates easier building configration construction by converting from a templatized Google Sheet to a [building configuration file](./ontology/docs/building_config.md) (and from a building configuration file back to a Google Sheet).
