The Data Hub API provides access to information that is managed by SAS Visual Investigator. This API facilitates describing data that resides in either internal writable databases or external customer-controlled read-only databases. Once the data definitions are provided as entity types, the data becomes accessible within SAS Visual Investigator. This API also provides mechanisms for fetching individual entity records that were defined by the entity type definitions. <br/> <br/>

Retrieves headers for a representation of a field value for a child document at a certain point in its history. If the field is currently configured for masking, and if the requesting user is authorized to reveal the value of the masked field, the request will succeed. If the field is currently configured for masking and the requesting user is not authorized to reveal the value of the masked field, the request will fail.

Conditional Expression

This type represents an individual result from counting the relationship links for a document. The "linkCount" property contains the total number of links that were found for each type. There will be one entry for each "to" entity type. Note that if the relationship type is  heterogeneous, then the "from" entity type will have a value, but the "to" entity type will be null.

Document and Link Bundle

Document Collection

A request to filter a collection of documents.

Document Filter Request

A request for a collection of documents by ID.

Document ID Request

The result of a bulk patch operation on a single document, optionally enriched with the full document representation. On success, `id`, `entityType`, `operation`, and optionally `document` are populated. On failure, `error` is populated with details about the failure.

Field Masking Configuration

A data object field that is used as an Expression in queries and SortCriteria.

Field Reference Expression

A representation of the set of field restrictions that are applied to a single field. Not every type of restriction applies to every field. For example, the "maxLength" restriction does not apply to numerical fields, but "precision" and "scale" might. Note that many endpoints documented in this REST API populate only a subset of these field restrictions (often only "masked").


Field Restriction

Represents a bundle of field restrictions for related data object types, as a map of object type name to Restricted Fields Map object. The keys of this map are strings representing object type names. The value mapped by each key is the Restricted Fields Map object for that data object type. The purpose of this representation is to allow the field restrictions for a top-level entity type to be bundled with the field restrictions for all of its child entity types, in one map. In this case, the top-level entity name and the child entity names will all be sibling keys in the Field Restrictions Bundle map.
