Although very similar, the Fedora 6 Transactions API is not backwards compatible with previous versions
This API is an implementation of the Fedora Atomic Batch Operations Specification After retrieving a transaction URI from the "Location" header in the response to the following HTTP request, the client can execute any POST/PUT/PATCH/DELETE/GET REST API method within the transaction scope by including the transaction URI in the "Atomic-ID" request header. Transactions are automatically closed and rolled back after 3 minutes of inactivity. Transactions can be refreshed by POSTing to the transaction URI Example: Response: Usage: When a transaction has been created, it will return a Location header. Use this location (transaction URI) as the value of the "Atomic-ID" request header for performing REST API operations within the transaction. When you are done with the transaction, either commit the transaction to the repository by making a PUT request to the transaction URI, or discard the changes and rollback the transaction by making a DELETE request to the transaction URI. Status: 201 Created: if the transaction is created successfully To get the status of a transaction, perform a GET request on the transaction URI that was previously returned as the value of the "Location" header from the transaction creation request. The "Atomic-Expires" header indicates the time at which the transaction will auto-rollback. Example: Response: Status: 204 No Content: If the request was successful 404Not Found: Transaction not found By performing a POST request on an existing transaction URI, the transaction's expiration time is extended by the value of the session timeout duration (default: 3 minutes) Example: Response: Status: 204 No Content: if the transaction is renewed successfully 404Not Found: if the transaction doesn't exist Example: Response: Status: 204 No Content: if the transaction is committed successfully 404 Not Found: if the transaction doesn't exist Example: Response: Status: 204 No Content: if the transaction is discarded successfully 410 Gone: if the transaction has already been committed or rolled back 404 Not Found: if the transaction does not exist POST Create a new transaction

PUT Commit an open transaction
Any operations you made within the scope of the transaction will be applied together, meaning if any of them fail, the whole transaction will fail.curl -X PUT "http://localhost:8080/rest/fcr:tx/ce4bb2bf-8ced-4c7d-b281-f2132e3064bb"
Status: 204 No Content
DELETE Rollback and close an open transaction
