| childDocuments.identifier | If this document has been split into a number of child documents, this attribute points to those child documents |
| pages | The number of pages in the document |
| isOcrd | Boolean indicating whether the document has had OCR applied to extract text (if false, the data was extracted from an existing text layer on the document) |
| ocrConfidence | Overall confidence in the accuracy of text extracted from the document by OCR |
| reviewUrl | A signed URL that is valid for 60 mins that can be used to review and validate the data extracted by the model. Learn more in Embedded Mode. |
| extractor | The Extractor that is associated with the Collection. An Extractor is an AI model used to extract data from documents |
| confirmedDt | The date-time when the document was confirmed |
| isConfirmed | Boolean to show if the document has been confirmed |
| rejectedDt | The date-time when the document was rejected |
| isRejected | Boolean to show if the document has been rejected |
| createdDt | The date-time when the document was created in Affinda |
| errorCode | If document processing fails, will return an error code |
| errorDetail | If document processing fails, will detail error identified |
