- It is easier to build/test/deploy. With improved and localized unit testing you could most likely...
- release much quicker without having to use 1-2 weeks testing.
- release only the module(s) you changed.
- People who don not want to use NAS could instead just use the parts that fit their needs.
- For example people could use the harvest controllers and nothing else.
Harvest Control
...
Manager Component
- Remove the JMS dependency from the controller.
- Instead use a REST interface or some other means of exposing a simple extendable API.
- Remove the notion of channels from the controller.
- The management of organizing controllers into groups is left to the user of these APIs.
- Make the code independent of the rest of NAS so it can be used not only by NAS.
- Controllers should be deployed independently of the rest of NAS.
- Use a plugin architecture for core functionality. (Use classloaders)
- configure harvester
- build progress reports
- build metadata files when the job is complete
- upload data to persistant storage
- A controller is built for a specific harvester; H1, H3, API
- Extendable using custom commands that the plugins add to the controller. (Thinking beyond H3...)
- The API should include all required functions to control the harvest manager
