Working with Unified Attributes

The Schema Mapping page displays all source attributes, and allows you to map them to the attributes in the unified schema.

Creating a Unified Dataset

To Create a Unified Dataset

1. Select Create Unified Dataset on the right hand side of the screen. The left hand side will display each of the source attributes from every uploaded dataset.
2. Create the unified schema by editing the text box before choosing Create Unified Dataset. The default is [project name] - Unified Dataset. Once you choose the Create Unified Dataset, the screen changes to show that there are no unified attributes.

Creating Unified Attributes

To Create a Unified Attribute

1. Select Create a new unified attribute on the right hand side, or
2. Selecting one or more unmapped attributes on the left side and choose Bootstrap. Tamr launches the bootstrapping attributes process which:

• Groups together attributes with the same name
• Assigns source attributes to unified attributes
• Uses the same name for a unified attribute as the name of the source attribute. You can also change the name.

3. Once you create a unified attribute, drag and drop additional source attributes onto it.

Naming Unified Attributes

Unified attributes must have names that conform to the following:

• Names cannot contain the . (period) character
• Names cannot match (case-insensitively) any other unified attribute in your project
• Names cannot be empty, and cannot contain leading or trailing whitespace
• Names cannot match (case-insensitively) these Tamr-generated attribute names:
• tamr_id
• origin_source_name
• origin_entity_id
• clusterId
• originSourceId
• originEntityId
• sourceId
• entityId

If there is a source attribute that you choose not to map, hover over the Unmapped label, and select Do not map this attribute. You can also select this option from the Map drop-down menu.

You can map multiple source attributes using the Map drop-down menu.

Tip

A helpful strategy for mapping is to filter input dataset attributes to display only the Unmapped attributes. This will display only those input attributes which have not been mapped.

Editing Unified Attributes

If a source attribute is incorrectly mapped to a unified attribute, hover over the list of mapped source attributes, and select the attribute from the list.

You can also unmap input dataset attributes from the left-hand panel. Hovering over the name of the unified attribute reveals the option to toggle mapping for the attribute.

Changing the Unified Attribute Type

Another important aspect of the unified attribute is deciding whether Tamr will treat it as a number or a string value. The attribute's type affects the approaches Tamr uses for machine learning.

To toggle the attribute type, choose the three dot menu to the right of each unified attribute.

Deleting a Unified Attribute

To delete a unified attribute, select it and choose Remove.

Updating a Unified Dataset

To update a unified dataset:

1. Navigate to the Schema Mapping tab of any project.
2. Choose Update Unified Dataset.
