Stefan Seifert commented on SLING-6025:
---------------------------------------
i'll try an experiment with a bnd plugin. benefit is: it should work with both
maven-bundle-plugin and bnd-maven-plugin.
where should we store the build-time generated metadata files to (default
value, configurable)?
* OSGI-INF/xxx is not good, its sling-specific
* SLING-INF or SLING-INF/xxx ist not good because SLING-INF is often used as
sling-initial-content, may conflict when the developers is not aware of it.
* SLING-CONTEXTAWARE-CONFIG-INF is quite long, but on the safe side...
> Context-Aware Config: Provide configuration parameter metadata

> in order to support configuration editors GUIs we need to provide metadata
> which configurations with parameter metadata are defined by the applications.
> this means:
> * list of all configurations registered (singleton, collections, nested) with
> ** their respective configuration names
> ** label (optional)
> ** description (optional)
> * list of all parameters for each configuration
> * parameter metadata:
> ** name
> ** type (only supported: String,int,long,double,boolean and arrays of them)
> ** label (optional)
> ** description (optional)
> ** default value
> ** further custom properties that may customized the configuration editor
> (e.g. widget type to use, optional)
> the applications needs a possibility to provide such configuration+parameter
> metadata. by default the annotation interface classes are used for this. they
> have to be detected on the runtime in the classpath when a new bundle is
> deployed using an osgi extender pattern (quite similar to sling models). to
> the annotation classes further annotations can be applied an class and
> property level to provide the additional metadata (label, description etc.).
> currently we can only support automatic detection of parameter metadata for
> configurations which are defined and accessed with annotation classes, not
> when the application used direct valuemap access or the low-level
> ConfigurationResourceResolver.
> by making the configuration metadata provider pluggable via an SPI we can
> ship the default configuration providing metadata detected from the deployed
> annotation classes, but leave a door open to add other sources as well.
