There are two ways you can integrate this with Rave.
1. Put a service facade onto the Role store to expose the JSON REST API that
Rave currently expects
2. Override the implementation classes in Rave to work with the ROLE SPARQL
endpoint
The first option is probably the best as it makes it much easier to switch
between marketplaces just using the Rave admin UI, and Rave users don't need to
do any special configuration to use your marketplace with a default setup.
OMELETTE have taken this approach; their repository also uses RDF and SPARQL
natively, but provide a service facade for integration.
However, if you want to put an alternative implementation in Rave thats doable
also; you'd need to provide an alternative implementation of
org.apache.rave.portal.service.WidgetMarketplaceService and override
DefaultWidgetMarketplaceService in deployment.
