REST Resource: projects.locations.entryGroups.entries

Resource: Entry

Entry metadata. A Data Catalog entry represents another resource in Google Cloud Platform (such as a BigQuery dataset or a Pub/Sub topic) or outside of it. You can use the linkedResource field in the entry resource to refer to the original resource ID of the source system.

An entry resource contains resource details, for example, its schema. Additionally, you can attach flexible metadata to an entry in the form of a Tag.

Output only. The resource name of an entry in URL format.

Note: The entry itself and its child resources might not be stored in the location specified in its name.
linkedResource

string

The resource this metadata entry refers to.

For Google Cloud Platform resources, linkedResource is the Full Resource Name. For example, the linkedResource for a table resource from BigQuery is:

//bigquery.googleapis.com/projects/{PROJECT_ID}/datasets/{DATASET_ID}/tables/{TABLE_ID}

Output only when the entry is one of the types in the EntryType enum.

For entries with a userSpecifiedType, this field is optional and defaults to an empty string.

The resource string must contain only letters (a-z, A-Z), numbers (0-9), underscores (_), periods (.), colons (:), slashes (/), dashes (-), and hashes (#). The maximum size is 200 bytes when encoded in UTF-8.
