Presently, there are two possible use cases in the current existing technical arrangements of SFTP. The below use cases are examples of how to replace the TDA-based exchange using the new DAS Rest API.
Use Case 1 - Document Registration by OFF to WIPO DAS with upload of the document content
| OFF uploads a request zip package file to sftp.wipo.int for registration | POST https://{wipo-hostname}/am/oauth2/access_token | OFF uses the OFF private key to generate the JWT client assertion (see more details) to request a valid access-token to WIPO DAS |
| POST https://{wipo-hostname}/requests/url-uploads | OFF sends a request to get a URL to upload the priority document content | |
| PUT {url-upload} | OFF uses the url-upload to upload the actual file content | |
| GET https://{wipo-hostname}/requests/url-uploads | OFF checks the readiness of the uploaded file for registration. This is because WIPO DAS performs a PDDP package file validation. | |
| POST https://{wipo-hostname}/requests/registrations | OFF sends the document registration request after receiving a successful status of the previous file upload, receives an ackId and the request status | |
| OFF downloads a response file from sftp.wipo.int to check registration result | ||
| Existing flow operated with SFTP | New flow using DAS Rest API | |
|---|---|---|
Use Case 2 - Document Retrieval to WIPO DAS by OSF
| Existing flow operated with SFTP | New flow using DAS Rest API with notifications of document availability | |
|---|---|---|
| OSF uploads a request zip package file to sftp.wipo.int for s document retrieval | POST https://{wipo-hostname}/am/oauth2/access_token | OSF uses the OSF private key to generate the JWT client assertion (see more details) to request a valid access-token to WIPO DAS |
| POST https://{wipo-hostname}/requests/retrievals | OSF sends a document retrieval request, receives an ackId and the request status | |
| As a result, OSF downloads a response file from sftp.wipo.int to check retrieval result and if successful the requested document is provided in the response file | GET https://{wipo-hostname}/requests/retrievals | OSF downloads the requested document |
Note: There is no document size limitation
