[jira] [Issue Comment Edited] (STANBOL-371) Change Jobmanager api to take care of chains

I think it would be better to implement this by

* supporting multiple JobManger services
* add an implementation that supports chains (there might be several different)
* add the Chain(s) supported by an instance as OSGI property (e.g. "org.apache.stanbol.enhancer.chain")

Clients that want to enhance a ContentIem by using a specific chain could than use a Filter like:

    (& 
        (objectClass=org.apache.stanbol.enhancer.servicesapi.JobManager)
        (org.apache.stanbol.enhancer.chain={chain-name})
    )

this would inject/find/track the JobManager instance for a specific chain.

WDYT


BTW: I am currently investigating how to implement a JobManager that supports asynchronous processing by using the OSGI Wire interface (support for consumer/producer pattern with OSGI components as consumer and producers). This JobManager could also support simple "chains" (configured sets of EnhancementEngines orderd by the "ordering" properties).
