Tomek Rękawek updated SLING-4223:
---------------------------------
    Attachment: SLING-4223.patch

I prepared a strawman patch, according to the JIRA description. The {{ContentReader.PROPERTY_TYPE}} property on the {{ContentReader}} is not used anywhere yet. Oliver, Felix, Bruce - could you take a look and give some feedback?

> The current Content Loader supports a basic set of import formats which are identified by extension: {{.xml}}, {{.jcr.xml}}, {{.json}}, {{.jar}} and {{.zip}}.
> There is a [user request|http://mail-archives.apache.org/mod_mbox/sling-users/201412.mbox/%3cD0A6198C.20FBEB%25bruce.edge@nextissuemedia.com%3e] to support custom formats like Adobe Folio and [some ideas how to implement|http://mail-archives.apache.org/mod_mbox/sling-users/201412.mbox/%3cA2AB572F-FA83-4AE2-806E-49CCE87B9FBE@adobe.com%3e]:
> * we create a new org.apache.sling.contentloader.reader package to be exported at version 1.0
> * move the ContentCreator (@ProviderType) and ContentReader (@ConsumerType) to that new package
> * convert the BaseImportLoader into a standalone ContentReader service holder used by the DefaultContentImporter and ContentLoaderService components.
> * For the ContentReader service interface we define service registration properties for the service to expose the file name extension (and maybe content type) the reader supports.
