Exchange flow to retrieve document transmitted by OFF to WIPO DAS transit zone
- OSF sends a document retrieval request to WIPO DAS and receives a request acknowledgement id issued by WIPO DAS (i.e. POST /das/v1/requests/retrievals)
- WIPO DAS forwards the retrieval request to the OFF and receives a request acknowledgement id issued by OFF (i.e. POST /das/v1/requests/retrievals)
- OFF requests a presigned url from WIPO DAS to upload a file and receives the file id from WIPO DAS (i.e. POST /das/v1/requests/url-uploads)
- OFF uploads the requested document file content into DAS transit zone using a presigned url given in step 3
- OFF notifies WIPO DAS of the document availability by referring to the request acknowledgement id returned in step 2 (i.e. POST /das/v1/requests/notifications)
- WIPO DAS prepares the requested document for download by OSF and notifies the OSF of the document availability by referring to the request acknowledgement id returned in step 1 (i.e. POST /das/v1/requests/notifications)
- OSF retrieves the file location URL to download the document file content by referring to the request acknowledgement id returned in step 1 (i.e. GET /das/v1/requests/files/url-downloads)
- OSF downloads the file using the URL obtained in step 8
- Optionally OSF deletes the download file from the DAS transit zone (i.e. DELETE /das/v1/requests/files)
