title: Searching the Catalog
description: Searching the Catalog.
---
Audience: Developers
## Overview
The Catalog can be searched by any combination of owner, kind, type, lifecycle, processing status, namespace, and name. [Customize Filters](../features/software-catalog/catalog-customization.md#customize-filters) provides information on how to modify the available search criteria.
![Catalog search options](../assets/uiguide/catalog-search-options.png)
The [Technical Overview](../overview/technical-overview.md) provides greater detail, but the catalog displays two main types of entities:
- Core Entities
- `Components` - Individual pieces of software that can be tracked in source control and can implement APIs for other components to consume.
- `APIs` - Implemented by components and form the boundaries between different components. The API can be either public, restricted, or private.
- `Resources` - The physical or virtual infrastructure needed to operate a component.
- Organizational Entities
- `User` - A person, such as an employee, contractor, or similar.
- `Group` - An organizational entity, such as a team, business unit, and so on.
There are three additional items that can be part of the system model:
- `Location` - A marker that references other places to look for catalog data.
- `Type` - It has no set meaning. You can assign your own types and use them as desired.
- `Template` - Describes both the parameters that are rendered in the frontend part of the scaffolding wizard, and the steps that are executed when scaffolding that component.
## Searching for an entity
You can search for an entity using a combination of the following:
- **Search by name**
Enter one or more consecutive letters into the `Filter` field. As you type the letters, the entities whose names do not contain that string will be filtered out of the displayed list.
![Search catalog by name](../assets/uiguide/search-by-name.png)
- **Search by kind**
Use the `Kind` dropdown list to select which kind of entity to show in the list:
- API
- Component
- Group
- Location
- System
- Template
- User
- **Search by Type**
Use the `Type` dropdown list to select which type of entity to show in the list. The selections available in the dropdown list depend on the kind of entity selected in the `Kind` list, and the types of entity you have registered for that kind.
- **Search by Owner**
Use the`Owner` dropdown to filter the catalog list by who owns the entity.
- **Search by Lifecycle**
Use the `Lifecycle` dropdown to filter the catalog list by lifecycle.
- **Search by Processing Status**
Use the `Processing Status` dropdown to restrict the displayed list to only include those entities which are [orphaned](../features/software-catalog/life-of-an-entity.md#orphaning) or [in error](../features/software-catalog/life-of-an-entity.md#errors).
- **Search by Namespace**
Use the `Namespace` dropdown to filter the catalog list by namespace associated with the entity.

description: Unregistering and deleting a component from the catalog

Audience: Developers
## Overview
URLs to YAML files that you registered either using the `Create` button or by adding to your app-config file are both handled by entity providers.
[Implicit deletion](../features/software-catalog/life-of-an-entity.md#implicit-deletion) occurs when an entity provider issues a deletion of an entity. That entity, as well as the entire tree of entities processed out of it are considered for immediate deletion.
However, you are also able to manually unregister an entity from the catalog or perform a direct, [explicit deletion](../features/software-catalog/life-of-an-entity.md#explicit-deletion), of individual entities. This is especially useful for removing [orphaned entities](../features/software-catalog/life-of-an-entity.md#orphaning).
## Unregistering an entity
You can unregister an entity so it will not be displayed in the Catalog but still keep its `catalog-info.yaml` file in the repository. This provides the ability to register the entity with the Catalog again in the future.
To unregister an entity:
1. In the Catalog, select the entity you want to unregister. In this example, `mytutorial` is being unregistered.
2. Select the three dots.
3. Select `Unregister entity` in the dropdown menu.
![Screenshot of selecting unregister entity.](../assets/uiguide/select-unregister-entity-from-three-dots.png)
4. Select `UNREGISTER LOCATION`. The entity is removed from the Catalog.
![Screenshot of confirming unregister entity.](../assets/uiguide/confirm-unregister-entity.png)
## Deleting an entity
You can also delete an entity from the catalog. However, this requires that you also delete the `catalog-info.yaml` entity definition file associated with the entity.
To delete an entity:
1. Delete the following entity definition files for the entity in the repository:
- catalog-info.yaml
- index.js
- package.json
2. In the Backstage App Catalog view, select the entity being deleted. In this example, `mytutorial` is being deleted.
Since you have deleted the entity definition files, an error is displayed that states the `catalog-info.yaml` file cannot be found.
![Screenshot of error finding catalog info yaml file.](../assets/uiguide/error-message-catalog-info-file-deleted.png)
3. Select the three dots.
4. Select `Unregister entity` in the dropdown menu.
![Screenshot of selecting unregister entity.](../assets/uiguide/select-unregister-entity-from-three-dots.png)
5. Select `ADVANCED OPTIONS`.
![Screenshot of selecting advanced options.](../assets/uiguide/select-advanced-options.png)
6. Select `DELETE ENTITY`.
![Screenshot of selecting delete entity.](../assets/uiguide/select-delete-entity.png)
A confirmation message that the entity has been successfully deleted is briefly displayed.The entity is no longer displayed in the Catalog.

## Overview
When you first log into your standalone Backstage App, `Home` is selected in the sidebar, which displays the Catalog in the main panel.
![Portal with annotations.](../assets/uiguide/portal-with-annotations.png)
The [Technical Overview](../overview/technical-overview.md) provides greater detail, but the catalog displays two main kinds of registered entities:
- **Core Entities**
- `Components` - Individual pieces of software that can be tracked in source control and can implement APIs for other components to consume.
- `APIs` - Implemented by components and form the boundaries between different components. The API can be either public, restricted, or private.
- `Resources` - The physical or virtual infrastructure needed to operate a component.
- **Organizational Entities**
- `User` - A person, such as an employee, contractor, or similar.
- `Group` - An organizational entity, such as a team, business unit, and so on.
There are three additional items that can be part of the system model:
- `Location` - A marker that references other places to look for catalog data.
- `Type` - It has no set meaning. You can assign your own types and use them as desired.
- `Template` - Describes both the parameters that are rendered in the frontend part of the scaffolding wizard, and the steps that are executed when scaffolding that component.
It should be noted that you can also [create your own kinds of entities](../features/software-catalog/extending-the-model.md#adding-a-new-kind), if you need to model something in your organization that does not map to one of the existing entity types.
Initially, the Catalog displays registered entities matching the following filter settings:
- `Kind` - Component
- `Type` - all
- `Owner` - Owned
- `Lifecycle` - list of lifecycle values of entities in the Catalog
- `Processing Status` - normal
- `Namespace` - The ID of a [namespace](../features/software-catalog/descriptor-format.md#namespace-optional) to which the entity belongs
You can change the initial setting for the [Owner](../features/software-catalog/catalog-customization.md#initially-selected-filter) and [Kind](../features/software-catalog/catalog-customization.md#initially-selected-kind) filters.
## Informational columns for each entity
For each kind of entity, a set of columns display information regarding the entity. For example, the default set of information for a `Component` is:
- `Name` - the name of the component
- `System` - an optional field that references the system to which the component belongs
- `Owner` - the owner of the component
- `Type` - common types are as follows, but you can [create a new type](../features/software-catalog/extending-the-model.md#adding-a-new-kind) to meet your organization's needs
- `service` - a backend service, typically exposing an API
- `website` - a website
- `library` - a software library, such as an npm module or a Java library
- `Lifecyle`
- `experimental` - an experiment or early, non-production component, signaling
that users may not prefer to consume it over other more established
components, or that there are low or no reliability guarantees
- `production` - an established, owned, maintained component
- `deprecated` - a component that is at the end of its lifecycle, and may
disappear at a later point in time
- `Description` - an optional field that describes the component.
- `Tags` - an optional field that can be used for searching
- `Actions` - see [Catalog Actions](#catalog-actions)
You can modify the columns associated with each kind of entity, following the instructions in [Customize Columns](../features/software-catalog/catalog-customization.md#customize-actions).
## Catalog Actions
For each entity, there are a set of actions that are available.
- View - View the `catalog-info.yaml` file that defines the entity.
- Edit - Edit the `catalog-info.yaml` file that defines the entity. See [Updating a Component](../getting-started/update-a-component.md)
- Star - Designate the entity as a favorite. You can filter and [search](../getting-started/search-catalog.md) for starred entities.
![Screenshot explaining entity actions.](../assets/uiguide/entity-actions.png)
[Customize Actions](../features/software-catalog/catalog-customization.md#customize-actions) describes how you can modify the actions that are displayed.
## Viewing entity details
Selecting a entity in the main panel displays details of the entity. The type of details depends on the type of entity. For example, selecting a Component, such as `example-website`, displays the following details:
- `About` - Metadata for the entity, such as description, owner,tags,and domain.
- `Relations` - see [Viewing entity relations](#viewing-entitiy-relationships)
- `Links` - any links associated with the entity
- `Has subcomponents` - An entity reference to another component of which the component is a part
Selecting a System, such as `examples`, displays `About`, `Relations`, and `Links` similar to a Component, but it also includes `Has components`, `APIs` and `Has Resources`.

title: Viewing entity relationships
description: View the relationships between the entities in the Catalog
---
Audience: Developers
Each of the entities in the Catalog have various relationships to each other. For example, the demo data includes an API that provides data to a website. `guests` is the owner of the API and the website, and anyone signed in as part of the `guests` group can maintain them.
To see these relationships:
1. Select the name of the component in the main panel, in this example, `example-website`.
![Screenshot of the Backstage portal with example-website selected.](../assets/uiguide/select-example-website.png)
A page is displayed that includes a `Relations` section. This section displays the selected entity and any other types of entities to which it is related. Each relationship is also designated, such as `hasPart/partOf` and `apiProvidedBy/providesApi`. [Well-known Relations between Catalog Entities](../features/software-catalog/well-known-relations.md) describes the most common relationships but you can also [create your own relationships](../features/software-catalog/extending-the-model.md#adding-a-new-relation-type).
Selecting any of the related entities allows you to drill down further through the system model.
![Screenshot of the example-website Relations panel.](../assets/uiguide/example-website-relationships.png)
## Filtering the relationships
You can also view the relationships in the [Catalog Graph](../features/software-catalog/creating-the-catalog-graph.md). This view allows you to filter what entities and relationships to display.
To display the Catalog Graph:
1. Select the name of the component in the main panel, in this example, `example-website`.
A page is displayed that includes a `Relations` section.
2. Select `View graph` in the `Relations` section.
![Select View graph.](../assets/uiguide/select-view-graph.png)
The `Catalog Graph` is displayed.
![Screenshot of Catalog Graph.](../assets/uiguide/catalog-graph.png)
You can set the following filters:
- `MAX DEPTH` - 1 or infinite
![Max Depth at 1 and infinite.](../assets/uiguide/max-depth-1-and-infinite.png)
- `KINDS` - select what kinds of entities you want to view, default is all kinds
- `RELATIONS` - select which relationships you want to view, default is all relationships
- `Direction`- orientation in which you want to view the entity and its associated nodes
- Top to bottom
- Bottom to top
- Left to right
- Right to left
- `Curve`
- Monotone
- Step Before
![Curve at Monotone and Step Before.](../assets/uiguide/curve-monotone-step-before.png)
You can also toggle:
- `Simplified`
- On = simple view
- Off = detailed view
- `Merge relations`
- On = You see the relationship from the selected entity to the nodes and from the nodes to the selected entity.
- Off = You only see relations from the selected entity to its nodes.

![Screenshot of the Backstage portal with example-website selected.](../assets/uiguide/select-example-website.png)
A page is displayed that includes a `Relations` section. This section displays the selected entity and any other types of entities to which it is related. Each relationship is also designated, such as `hasPart/partOf` and `apiProvidedBy/providesApi`. [Well-known Relations between Catalog Entities](../features/software-catalog/well-known-relations.md) describes the most common relationships but you can also [create your own relationships](../features/software-catalog/extending-the-model.md#adding-a-new-relation-type).
Selecting any of the related entities allows you to drill down further through the system model.
