| 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 | POST /das/v1/requests/url-downloads | 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) |
