# Creating a Set
{% hint style="info" %}
Registry Administrators and Registry Maintainers can create sets for the Geo-Object Types under the curation mandate of their organization.
{% endhint %}
A set is the configuration that defines a container for creating versions of lists. See [Key terms](/version/v2.0.0/explore/lists-and-spatial-data.md#key-terms).
1. Navigate to the **Lists and Spatial Data** page from the sidebar. On the left, click the Geo-Object Type under its organization.
2. Click **Create New List and Spatial Data**.
3. The **Configuration** window opens. Choose the type of set. It can't be changed later.
* **Single date:** one list of the data as it was on a single date.
* **Frequency-based:** a list for each period at a fixed frequency from a start date.
* **Period-based:** a list for each period you define.
4. Fill out the form:
| Field | Description | Required |
| ------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | -------- |
| Code | The unique identifier of the set. A code is generated for you, and you can replace it. It can't be changed later. | Required |
| Title | The title of the set, with one field per installed locale. | Required |
| Description (Abstract) | A description of the set, with one field per installed locale. | Required |
| Geo-Object Type, Geo-Object Type Code | The Geo-Object Type the set covers. Filled in automatically. | |
| Include Latitude and Longitude | For point Geo-Object Types, adds latitude and longitude columns to the list. Selected by default. | |
| Hierarchies | One row for each hierarchy the Geo-Object Type belongs to. Select parent Geo-Object Types to add their codes and labels as columns. | |
| Group hierarchies | For a group, the hierarchies of the Geo-Object Types in the group. | |
| Filter | Only include Geo-Objects that match. Choose an attribute, a condition (**Equals**, or **Exact** for a classification) and a value. Click **New** to add another filter. Filters can only be set when the set is created. | |
5. Fill out the dates for the type of set you chose:
* **Single date:** the **Valid For** date.
* **Frequency-based:** the **Frequency** (**Annual**, **Biannual**, **Quarter** or **Monthly**) and the **Start date**.
* **Period-based:** click **New** to add each period, and enter its **Start Date** and **End Date**. Periods can't overlap. A warning appears if there's a gap between periods.
6. Fill out the **Metadata** section. It has a **List** tab and a **Spatial Data** tab, and both have these fields:
```
| Field | Description |
| ----- | ----------- |
| Title | The title, with one field per installed locale. |
| Credit | Credits given to any individuals or groups. |
| Description (Abstract) | A description of the contents. |
| Process | The process used to create and curate the data. |
| Status | The progress so far in creating and curating the data (for example, ongoing or completed). |
| Access Constraints | Any access constraints. |
| Use Constraints | Any use constraints. |
| Acknowledgements | Any acknowledgements related to the data. |
| Disclaimer | The disclaimer. |
| Contact name, Telephone Number, Email Address | The person to contact with questions (under **Primary contact**). |
```
The **Spatial Data** tab also has:
```
| Field | Description |
| ----- | ----------- |
| Topic Categories | Topics covered by the spatial data. |
| Place Keywords | Keywords describing the places covered. |
| Update Frequency | How often the spatial data is updated. |
| Lineage | The process history or overall quality of the spatial data. |
| Languages | The languages the spatial data is captured in. |
| Scale or Resolution | The scale or resolution the spatial data was captured at. |
| Spatial Representation Type | Always **Vector**. |
| Reference System | Always **EPSG 4326 (WGS 84)**. |
| Report and Specification | A link to the report and specification of the spatial data. |
| Distribution Format | Always **Shapefile**. |
```
7. Click **Submit**. Geoprism Registry creates a working version for each date or period of the set.
8. The set appears on the page. Click its title to open it.
## Setting visibility and authoritativeness
Each version's **List** and **Spatial Data** has its own visibility and authoritativeness. You set them in the version's metadata.
1. Open the set and click **Metadata** next to the working version.
2. On the **List** and **Spatial Data** tabs, set:
* **Is Master:** select this if the list or spatial data is the master (authoritative) data.
* **Visibility:** **Public** (visible to all organizations) or **Private** (visible only to your organization). Public isn't available for a private Geo-Object Type.
3. Click **Submit**.
