# Metadata glossary

Benchling In Vivo entities that can attach metadata can store a glossary field, used to design a schema. For example you can set metadata to be a select field, or a date field.

Supported field types: `text`, `select`, `multi_select`, `lookup_select`, `lookup_multi_select`, `date`, `numeric`.

> **Note**
>
> The `lookup_select` and `lookup_multi_select` field types are only supported for `study`, `group`, `treatment`, and `disease` metadata.

> **Note**
>
> For `attachment` metadata, the `multi_select` field type is **not supported**.
