Exchange flow to retrieve document hosted in WIPO DAS - (2a) - OSF sends a document retrieval request to WIPO DAS and receives a request acknowledgement id (i.e. 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) (i.e. POST /das/v1/requests/notifications)
| Note |
|---|
| 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 (i.e. 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 (i.e. DELETE /das/v1/requests/files)
| Note |
|---|
| If OSF does not delete the downloaded file, WIPO DAS will delete it after a pre-defined period (e.g. 1 week) |
