Smart document split
Add automatic document splitting to workflows.
In cases where a single PDF file contains multiple underlying documents, smart-split allows for the automatic detection and segmentation of sub-documents. Even in cases where sub-documents have variable lengths and format.
When a source file is uploaded, it is processed and a corresponding
fileId is assigned. The /results/ for the original file will then contain one or more child document fileIds which can then be queried to obtain the corresponding sub-document results.Document splitting can be used in conjunction with other standard workflows like prediction or validation.
Sample combination of document splitting and validation.
To automatically split files on upload, a few changes to the standard
fileupload form-data parameters are required:- Specify the document-splitting workflow type by setting:
workflowId=split - Specify a
childWorkflowIdto define what workflow to run on each generated sub-document - Optionally specify
childWorkflowOptionsto parameterise the workflow run on each generated sub-document
Split workflows are a
BETA feature and subject to change.

Limitations, Errors and Recommendations
- Uploading a document for the split worflow does not enforce any page limit checks. You may upload a document of any size but recent tests have shown we cannot process more than 50 pages at this time.
- Any split documents will be checked for page limits. To avoid this scenario please ask to have your page limit increased to your expected maximum.
- If a split document is rejected due to page or file size limits, the split workflow will eventually be marked as failure. Some split documents my successfully upload however - this is not ideal and can be avoided by increasing your page limit as above.
