To provide user-friendly business context to technical assets, you can associate glossary assets with data elements. A glossary is a collection of business-friendly terms, that when associated with technical assets, helps business users to manage technical data using terminology that is more familiar to them. This leads to consistency and better governance across your organization.
Curate glossaries for technical assets
If you're a data owner or a business user, you can curate business glossaries for technical assets to add more context to your data and to make your data easily discoverable. Business glossaries comprise terminology that is familiar within your organization.
When you curate glossaries, you either accept or reject the glossaries recommended for technical assets, or you manually associate technical assets with one or more glossary assets. Data Governance and Catalog can also automatically associate suitable glossaries with technical assets. You can curate the glossaries on the Overview tab or on the Contains tab of technical asset pages in Data Governance and Catalog.
The following guidelines apply if you want to curate glossaries for technical assets:
•The associated glossary asset type can be a business term or a metric.
•The technical asset should be a data element or a technical data set.
•The glossary asset that you curate should be in the Published lifecycle stage.
•To curate glossary recommendations, the organization administrator must provide your user role the Curate Automatic Glossary Associations privilege for the Data Governance and Catalog service in Administrator.
•To modify the asset properties, you should be a stakeholder of the asset, and the organization administrator should provide your user role with the Create and Update permissions for the asset type.
Automatically associate glossary assets with technical assets
By using the power of CLAIRE®, Data Governance and Catalog can infer and automatically associate meaningful glossary assets with your technical assets.
When you open the Overview tab for a technical asset in the catalog source in Data Governance and Catalog, you may see glossary assets in the Accepted and CLAIRE® Recommendations sections of the Glossaries panel. These associations are made automatically by CLAIRE® based on the following criteria:
•All Glossary assets that match or exceed the specified confidence score are automatically accepted and appear in the Accepted list. The accepted glossary asset is thus assigned as the business name of the asset. If there are several automatically accepted glossary assets with the same confidence score, the first asset in the alphabetical order is assigned as the business name of the technical asset.
•All glossary assets that are below the specified confidence score appear as recommendations in the CLAIRE® Recommendations list. You can then manually accept or decline the recommendations as mentioned earlier.
The following image shows a sample asset page for a column named PHONE_NUMBER. The Glossaries panel shows the automatically accepted and CLAIRE® recommended terms.
In the above example image, the column named PHONE_NUMBER belongs to an Oracle catalog source. Let us assume that the confidence score threshold defined for the catalog source in Metadata Command Center is 86%. The business term Phone Number matches the column with a confidence score of 88%, and the term is automatically accepted as the business term for the column. Another business term Mobile number matches the table with the confidence score of 82%, which is lower than the defined confidence score, and the term Mobile number appears as a CLAIRE® recommendation. You can choose to accept or decline the recommendation.
Accept or decline recommended glossary assets
Based on the semantics of data contained in the technical assets, the system can recommend intelligent glossary suggestions for your technical assets. You can either accept or decline the recommendations.
The following image shows the CLAIRE® recommended term and the options for accepting or declining the recommendation for the sample column PHONE_NUMBER.
For each CLAIRE® recommendation, you can perform one of the following actions:
•Select Accept to accept the CLAIRE® recommendation. The glossary asset then moves to the Accepted list.
•Select Decline to decline the CLAIRE® recommendation. The glossary asset then moves to the Declined list.
•Select Accept and save as Business Name to accept the CLAIRE® recommendation and assign this glossary asset as the business name of the asset. The asset then moves to the Accepted list and the business name of the asset is assigned.
•Select Accept and Decline other CLAIRE Recommendations to accept only this glossary asset and decline other recommended assets. The accepted glossary asset then moves to the Accepted list and other recommendations are move to the Declined list.
Optionally, you can bulk accept or decline all CLAIRE® recommended glossary assets at once. You can also bulk accept all the declined glossary assets or decline all accepted glossary assets. The following image show the options for bulk accepting and declining glossary assets for a column.
Manually associate glossary assets with technical assets
If you want to associate specific business terms or metrics with technical assets, you can manually associate them. To manually associate glossary assets with technical assets, perform the following actions:
•The Glossaries panel on the Overview tab of a technical asset page displays the glossary assets that are already assigned to the asset. To manually associate other glossary assets, click the add icon on the Glossaries panel and select one or more business terms or metrics to associate with the technical asset.
If you select one business term or metric, then you can select the option to use the name and description of the selected glossary as the name and description of the technical asset. The selected glossary assets appears in the Accepted section of the Glossaries panel. The business name and description of the technical asset changes to the name and description of the glossary asset that you selected.
The following image shows the column asset page. In this example, the associated glossary Contact Number appears as the business name of the column and in the Accepted section of the Glossaries panel.
•Use the Curate button on the Contains tab of a technical data set page to manually associate glossaries with technical data elements. You can also see the glossary asset associations that are made automatically by CLAIRE®.
