Re[2]: [stp-dev] Proposal for a generic validation framework

[Alex <atelesh@xxxxxxxxxxx>]

Hi David!

    Unfortunately our proposal document does not contain
    clear description regarding to using OSGi background.
    Yes, you are correct OSGi services is more applicable
    for such purpose. Furthermore we already have sample
    implementation of OSGi-based Validation Framework
    which is used OSGi services in background. I hope we
    will provide our sample to Eclipse community soon.
    And the main idea of our validation framework API
    (with factory approach) is to provide general API
    knowing nothing about platform specific implementation
    (regardless to OSGi or another type of background runtime).
