# Additional Information

{% hint style="info" icon="lightbulb" %}

#### FAIR guidance

Throughout this documentation, you'll find explanations of why particular metadata are important and how they support the **Findability, Accessibility, Interoperability and Reusability (FAIR)** of your resource.

FAIRsharing helps resource providers describe their standards, databases and policies using rich, structured metadata that supports discovery, understanding and reuse by both people and software. These guidance notes explain why each field matters and how it contributes to making your resource more FAIR-enabling.

To learn more about FAIRsharing's approach to FAIR, see [**Alignment with FAIR**](/fairsharing/alignment-with-community-efforts.md#alignment-with-fair).

The "Additional Information" tab is used to provide registry-specific metadata, as opposed to the previous tabs which allow the update of metadata that is common to all FAIRsharing records.

## Standards

Standards records have the following sections within Additional Information:

* [Associated Tools](/fairsharing/additional-information/associated-tools.md)
* [Cross References](/fairsharing/additional-information/cross-references.md)
* [Data Processes](/fairsharing/additional-information/data-processes.md)
* [Regular expressions](/fairsharing/additional-information/regular-expressions.md): *optional, **Identifier Schema** subtype only.*

## Databases

Database records have the following sections within Additional Information:

* [Associated Tools](/fairsharing/additional-information/associated-tools.md)
* [Certification and Community Badges](/fairsharing/additional-information/certification-and-community-badges.md)
* [Cross References](/fairsharing/additional-information/cross-references.md)
* [Data Processes](/fairsharing/additional-information/data-processes.md)
* [Database Conditions](/fairsharing/additional-information/database-conditions.md)

## Policies

* [Policy Content and Scope](/fairsharing/additional-information/policy-content-and-scope.md)

## Collections

* **Reference URL**: This should be a direct link to a page either listing each of the resources included in the collection (if the collection is a live implementation of an already-released listing), or to a page describing the purpose/intent of the FAIRsharing collection as the primary source of this grouping of resources. In some small number of cases, where neither option is available, the curation team may choose to temporarily leave this field blank, until a suitable reference URL is provided by the maintainers.
