# Preferred ontologies and nomenclatures

The full schemas and data dictionaries of tables used in K-Pro can be provided upon request. Data loaded in K-Pro follows a OMOP like schema with the following notable categorical standards :

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.owkin.com/explore-and-analyse-data/k-pro-data-model-and-technical-references/preferred-ontologies-and-nomenclatures.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
