Data Catalog Resource¶
The EnOS Data Catalog enables you to query and manage the metadata information of the data assets in your organization (OU).
Metadata is data that describes other data and is often used in the following business scenarios.
- Describing objects such as information resources or data.
- Providing structured data about resources to identify resources, evaluate resources, and track changes of resources in its usage.
- Simply and efficiently managing a large amount of networked data to achieve the discovery, searching, integrated organization, and effective management of information resources.
For more information, see Data Catalog Overview.
Resource Application Scenario¶
Through Data Catalog, you can create new measurement points and query metadata information about measurement points, including basic information about measurement points, storage policy information, data archiving task information, and associated instance lists. Before creating a new observation point and inquiring metadata information of the observation point, it is necessary to apply for the Data Catalog resource.
Note
The maximum number of resource instances that can be applied for under each OU is 1.
