An asset in a catalog contains information about data or data analysis. A catalog can contain up to 50 assets.
The information about assets that is stored in a catalog includes:
- The type of asset
- Asset properties, such as the description and format.
- The asset access to control who can access the asset
- A preview of the contents of some asset types
Types of assets
You can add assets from these types of sources to a catalog:
- Files from your local system, including structured data, unstructured data, and images.
- Connections to data sources. You can add connections to IBM or third-party data sources.
- Data assets from a connection to a data source.
- Folder assets from a connection to a file system.You can use folder assets in Watson Knowledge Catalog only.
- Data assets from projects.
- Notebooks from projects.
- Trained Watson Machine Learning models from projects.
All asset types have a common set of properties. Some asset types have additional properties.
When you add an asset to a catalog or edit an existing asset, you specify these common properties:
- The asset name and an optional description. The asset name cannot be empty, contain Unicode control characters, or contain only blank spaces. You can include links in the description.
- Asset format. Automatically detected.
- Tags. Metadata that makes searching for the asset easier. Tags can contain only spaces, letters, numbers, underscores, dashes, and the symbols # and @. Click to add tags.
You can control access to an asset on the Access page with the privacy level and asset membership:
- Privacy. You can choose whether to restrict access to the asset:
- Public = Default. No restrictions on finding or using the asset.
- Private = Only asset members can find or use the asset.
- Members. The catalog collaborators to add as members of the asset. Members are important if you restrict access to the asset.
