Exchange flow to register document
| Step | API Request | Notes |
|---|---|---|
| (1a) - OFF requests a pre-signed URL from WIPO DAS to upload a file identified by a file id | POST /das/v1/requests/files/url-uploads | Not required if OFF keeps the actual document file content in its own digital library |
| (1b) - OFF uploads the document file content using a pre-signed URL given in step (step 1a) | File upload via PUT | |
| (1c) - OFF requests document registration to WIPO DAS by referring to the uploaded file content by the corresponding file id | POST /das/v1/requests/registrations |
Exchange flow to correct filing date or parent application details in which the foreign priority document is held
| Step | API Request | Notes |
|---|---|---|
| (1c) - OFF requests document registration to WIPO DAS by specifying the new document attributes | PUT /das/v1/requests/registrations |
Exchange flow to replace document content for correction purpose
| Step | API Request | Notes |
|---|---|---|
| (1a) - OFF requests a pre-signed URL from WIPO DAS to upload a file identified by a file id | POST /das/v1/requests/files/url-uploads | |
(1b) - OFF uploads the corrected document file content using a pre-signed URL given in step (1a) | ||
| (1c) - OFF requests document registration to WIPO DAS by referring to the uploaded file content by the corresponding file id | PUT /das/v1/requests/registrations |
Exchange flow to retrieve document hosted in WIPO DAS
| Step | API Request | Notes |
|---|---|---|
| (2a) - OSF sends a document retrieval request to WIPO DAS and receives a request acknowledgement id | POST /das/v1/requests/retrievals | |
| (2b) - WIPO DAS prepares the requested document for download and notifies the OSF of the document availability (i.e. Figure A) by referring to the request acknowledgement id returned in step (2a) | POST /das/v1/requests/notifications | Alternatively , OSF may use the check status (i.e. Figure B) to download the document content when it is reported as available by WIPO DAS (i.e. GET /das/v1/requests/retrievals) |
(2c) - OSF retrieves file location URL from WIPO DAS to download the document file content | Downloads can be repeated while the requested document is not deleted from WIPO DAS | |
(2d) - OSF downloads file from WIPO DAS | ||
| (2e) - Optionally OSF deletes the download files from the DAS transit zone | DELETE /das/v1/requests/files | If OSF does not delete the downloaded file, WIPO DAS will delete it after a pre-defined period (e.g. 1 week) |
