> Epic to track individual steps towards improved modularisation of Oak
> Until now Oak modules are all released together, which has some drawbacks. Work on the modules must be somewhat kept in lockstep. Releasing a fix for a module means all other modules must be in a state that can be released as well. For a user it may be desirable to just update a single module to get a fix and not a complete set of Oak bundles.
> The general approach for this epic should be to modularize only as needed and not split everything. Obvious candidates are stable interfaces like Oak and NodeStore API and NodeStore implementations.
> This requires fixing potential circular dependencies between logical modules we want to split up. We need a better distinction between the interface part of the SPI and its implementations. Utilities and commons code must be reviewed and potentially moved.
> The oak-it related dependencies should be reconsidered and that a development version of a NodeStore implementation can run integration tests. With the current dependency setup a release of the NodeStore implementation is required first to run the integration tests with those changes.
> Some modules will probably be moved to the top-level and have their own branches and tags.
> To avoid branches it is important to always have trunk stable. Feature work must happen on feature branches, in a forked module or protected with a feature flag until it is ready for prime time. No more unstable work in trunk.
> Module owner is primarily responsible for module releases. At some point there won't be a dedicated person anymore responsible for 'the Oak release'.
