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/>

  <li>Deleted an attachment</li>
</ul>
This representation contains detailed information about the action. For example, field value changes that occur when a document is edited.

The keys of this map are strings representing field names. The value mapped by each key is an Extended Field Properties object containing all the client field properties for the field with that name corresponding to the field's data type (if applicable).


Client Field Properties Field-Name Map

Represents a bundle of client field properties for related data object types, as a map of object type name to a Field Properties Map object. The keys of this map are strings representing object type names. The value mapped by each key is the Field Properties Field-Name Map object  for that data object type.

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.


Count Links Result

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.


Enriched Bulk Operation Result

A collection of enriched bulk operation results. Each item represents whether a bulk patch operation succeeded or failed for an individual document. Result items are in the same order as the input collection.


Enriched Bulk Operation Result Collection

Entity Type Summary

A representation of the masking configuration for a single field.


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.


Field Restrictions Bundle
