# Creating a Collection

## Overview

Create custom collections to organize and share specific datasets from your Publisher data sources. Collections are user-defined subsets of the data connected to Publisher.

## Creation Process

### Starting a New Collection

* Navigate to Collections in the sidebar
* Click "Create Collection" in the top-right corner
* You'll see a list of all available files and tables from your connected data sources

### Using Filters

Use the Filters panel (accessed via the filter icon) to define collection contents:

* Toggle between Files and Tables views
* Set conditions for:
  * File names
  * Filename suffixes
  * Data source types
  * Data source names
* Apply filters to update the view
* Multiple filters can be combined
* Active filters are displayed and can be removed individually

{% hint style="info" %}
To learn more about the filters, please see [Collection Filters](/products/publisher/collections/collection-filters.md)
{% endhint %}

### Collection Information

Provide required details about your collection:

* Name (e.g., "Precision Medicine Initiative")
* Description (study details, sample information, data types)
* URL (automatically formatted for web access)
* Tags (optional)

{% hint style="info" %}
This metadata can also be edited later. See [Editing Collection Metadata](/products/publisher/collections/editing-collection-metadata.md)
{% endhint %}

### Sharing Options

Configure data sharing services:

* Discovery: Makes collection metadata publicly visible
* Search: Enables content searching
* Download: Allows file downloads
* [Access Policy](/products/publisher/access-policies.md): Set permissions for collection access

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.omics.ai/products/publisher/collections/creating-a-collection.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
