Asset types and properties

Asset types and properties

The platform provides collaborative workspaces and tools, and you provide the content to the platform, in the form of assets. An asset is an item that contains information about data, other valuable information, or code that works with data.

You add assets by importing them or creating them with tools. You work with assets in collaborative workspaces. The workspace that you use depends on your tasks.

  • Projects Where you collaborate with others to work with data and create assets. Most tools are in projects and you run assets that contain code in projects. For example, you can import data, prepare data, analyze data, or create models in projects. See Projects.

  • Catalogs Where you store assets to share with your organization or go to find assets that you need to work with. You can copy assets from catalogs into projects, or publish assets from projects into the catalog. You can edit asset properties and metadata in a catalog, but you can't run assets. See Catalogs.

  • Deployment spaces Where you deploy and run assets that are ready for testing or production. You move assets from projects into deployment spaces and then create deployments from those assets. You monitor and update deployments as necessary. See Deployment spaces.

You can find any asset in any of the workspaces for which you are a collaborator by searching for it from the global search bar. See Searching for assets across the platform.

You can create many different types of assets, but all assets have some common properties:

Asset types

To create most types of assets, you must use a specific tool. Most tools are provided by one or more services. The tools to create data assets and connection assets are provided by the platform and do not require any specific services.

To see which services you need for which tools, open the tools and services map.

The following table lists the types of assets that you can create, the tools you need to create them, and the workspaces where you can add them.

Common properties for assets

Assets accumulate information in properties when you create them, use them, or when they are updated by automated processes. Some properties are provided by users and can be edited by users. Other properties are automatically provided by the system. Most system-provided properties can't be edited by users.

Common properties for assets everywhere

Most types of assets have the properties that are listed in the following table in all the workspaces where those asset types exist.

Common properties for assets
Property Description Editable?
Name The asset name. Can contain up to 255 characters. Supports multibyte characters. Cannot be empty, contain Unicode control characters, or contain only blank spaces. Asset names do not need to be unique within a project or deployment space. Whether asset names must be unique in a catalog depends on the duplicate handling method set for the catalog. Yes
Description Optional. Supports multibyte characters and hyperlinks. Yes
Creation date The timestamp of when the asset was created or imported. No
Creator or Owner The username or email address of the person who created or imported the asset. No
Last modified date The timestamp of when the asset was last modified. No
Last editor The username or email address of the person who last modified the asset. No

Common properties for assets in catalogs

In addition to the common properties that all assets have, assets in catalogs have the properties and pages that are listed in the following table.

Common properties for assets in catalogs
Property or page Description Editable?
Asset page A view of the contents of the asset. See Asset contents or previews. No
Privacy Set to public by default. This setting can restrict access to an asset in a catalog when set to private. Only the owner and members of the asset can view and use private assets. Yes
Access page The owner and members of the asset. By default, the asset owner is the user who added the asset to the catalog. The asset members can view and use the asset when it is marked private. See Controlling access to an asset. Yes
Ratings page Optional. Catalog collaborators can rate and review assets. Yes
Tags Optional. Text labels that catalog collaborators create to simplify searching. A tag consists of one string of up to 255 characters. It can contain spaces, letters, numbers, underscores, dashes, and the symbols # and @. Yes
Relationships Optional. Relationships that appear in the Related items section of the asset Overview page are informational and do not have other effects on the asset. Can be between assets in the same workspace or different workspaces. For example, you can add a relationship between an asset in a catalog and an asset in a project. Can be between an asset and an artifact. For example, you can add a relationship between an asset and a policy. Administrators can create custom relationships for assets. See Adding asset relationships. Yes
Governance artifacts Optional. The business terms and classification that users assigned to the asset. These assignments can affect the asset. For example, an assigned business term can trigger the enforcement of a data protection rule. Yes

You can create custom properties for asset types. Custom properties are shown in the Details section on the asset's Overview tab in the catalog. See Custom properties and relationships.

To edit asset properties, you must have the required permissions. See Editing assets in a catalog.

Common properties for assets that run in tools

Some assets are associated with running a tool. For example, an AutoAI experiment asset runs in the AutoAI tool. Assets that run in tools are also known as operational assets. Every time that you run assets in tools, you start a job. You can monitor and schedule jobs. Jobs use compute resources. Compute resources are measured in capacity unit hours (CUH) and are tracked. Depending on your service plans, you can have a limited amount of CUH per month, or pay for the CUH that you use every month.

For many assets that run in tools, you have a choice of the compute environment configuration to use. Typically, larger and faster environment configurations consume compute resources faster.

In addition to basic properties, most assets that run in tools contain the following types of information in projects:

Properties for assets in projects
Properties Description Editable? Workspaces
Environment definition The environment template, hardware specification, and software specification for running the asset. See Environments. Yes Projects, Spaces
Settings Information that defines how the asset is run. Specific to each type of asset. Yes Projects
Associated data assets The data that the asset is working on. Yes Projects
Jobs Information about how to run the asset, including the environment definition, schedule, and notification options. See Jobs. Yes Projects, Spaces

Data asset types and their properties

Data asset types contain metadata and other information about data, including how to access the data.

How you create a data asset depends on where your data is:

  • If your data is in a file, you upload the file from your local system to a project, catalog, or deployment space.

  • If your data is in a remote data source, you first create a connection asset that defines the connection to that data source. Then, you create a data asset by selecting the connection, the path or other structure, and the table or file that contains the data. This type of data asset is called a connected data asset.

    For data sources that support SQL queries, you can also create dynamic views, which are data assets of the type Query. To create such an asset, select the connection and provide an SQL query that retrieves only the data that you need.

The following graphic illustrates how data assets from files point to uploaded files in Cloud Object Storage. Connected data assets require a connection asset and point to data in a remote data source.

This graphic shows that data assets from files point to uploaded files and connected data assets require a connection asset and point to data in a remote data source.

You can create the following types of data assets in a project, catalog, or deployment space:

  • Data asset from a file Represents a file that you uploaded from your local system. The file is stored in the object storage container on the IBM Cloud Object Storage instance that is associated with the workspace. The contents of the file can include structured data, unstructured textual data, images, and other types of data. You can create a data asset with a file of any format. However, you can do more actions on CSV files than other file types. See Properties of data assets.

    You can create a data asset from a file by uploading a file in a workspace. You can also create data files with tools and convert them to assets. For example, you can create data assets from files with the Data Refinery, Jupyter notebook, and RStudio tools.

  • Connected data asset Represents a table, file, or folder that is accessed through a connection to a remote data source. The connection is defined in the connection asset that is associated with the connected data asset. You can create a connected data asset for every supported connection. When you access a connected data asset, the data is dynamically retrieved from the data source. See Properties of data assets.

    You can import connected data assets from a data source with the connected data tool in a workspace. If you want to import sets of connected data assets, for example an entire database schema, use the metadata import tool in projects. You can create virtual tables that compile data from multiple data sources with Watson Query in the Data virtualization workspace.

    In projects, you can create dynamic views that contain filtered data from one or more tables in a data source by using the query data-access tool.

  • Folder asset Represents a folder in IBM Cloud Object Storage. A folder data asset is special case of a connected data asset. You create a folder data asset by specifying the path to the folder and the IBM Cloud Object Storage connection asset. You can view the files and subfolders that share the path with the folder data asset. The files that you can view within the folder data asset are not themselves data assets. For example, you can create a folder data asset for a path that contains news feeds that are continuously updated. See Properties of data assets.

    You can import folder assets from IBM Cloud Object Storage with the connected data tool in a workspace.

  • Connection asset Contains the information necessary to create a connection to a data source. See Properties of connection assets.

    You can create connections with the connection tool in a workspace.

Property or page Description Editable? Workspaces
Columns A summary of the properties of the columns in the data asset. Includes the quality score, description, assigned data classes, and assigned business terms for each column. The assigned data classes and business terms can affect the asset. For example, an assigned business term can trigger the enforcement of a data protection rule.

Primary key and key relationship information:
• A column that is set as primary key is identified by a key icon (key icon. A primary key is also shown in the asset side panel.
