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/>

Gets 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 raw unmasked value of the field is returned. If the field is currently configured for masking and the requesting user is not authorized to reveal the value of the masked field, the result is an error.

The metadata that defines a class of entities. This definition includes a list of fields, language-specific labels, icons, and other relevant information.


Entity Type

A single field that is associated with an entity type object.

Entity Type Field

Entity Type Summary

The abstract parent class for expression types. Subclasses include the following expression types: <ul>
  <li>Arithmetic</li>
  <li>Boolean</li>
  <li>Conditional</li>
  <li>Field Reference</li>
  <li>Function Call</li>
  <li>Literal</li>
  <li>Logical</li>
  <li>Named Parameter</li>
  <li>String</li>
</ul>


Abstract Expression

Arithmetic expression of the form: leftOperand operator rightOperand. The expression evaluates to a Boolean result.

String Expression

A representation of the masking configuration for a single field.


Field Masking Configuration

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


Field Restriction

Represents all of the field restrictions of a datatype as a map of field name to field restriction object. The keys of this map are strings representing field names. The value mapped by each key is the Field Restriction object containing all the field restrictions for the field with that name.


Restricted Fields Map

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.


Field Restrictions Bundle

Field Value Collection

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.


Count Links Result

A list of count links result items. Each item provides a count of the number of links between the "from" entity and other entities of a specific type.


Count Links Result Collection

Represents a list of choices that the user can select as the value for a field. Common examples might include "Size" (small, medium, large) or "Color" (red, green, blue). In the first example, "Size" is the list and (small, medium, large) are items of that list.
