Overview
The LTA Manager or rs-lta-manager microservice (LTA : Long Term Archive request) has been designed to improve
interoperability between external applications and REGARDS OAIS catalog.
It provides a single service that let you create product and check creation progress and errors.
It is an optional service of the OAIS Services (Functional overview).
To do so, LTA Manager or rs-lta-manager provides these functionalities:
- OAIS Product creation
- the payload is lighter than the one used by OAIS catalog
- product can be enhancement by workers
- Get request status and errors - avoid you to connect to sub service used like
rs-worker-manager,rs-ingestandrs-storage.
LTA Manager or rs-lta-manager need a worker to transform LTA request to SIP.
This worker must be deployed and registered in
the rs-worker-manager microservice.
