-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've seen this happen loading custom vocabularies built by the Generic RDF Indexer and I'm honestly still not sure of why. In my case, restarting the custom bundle and the Solr Yard bundle seemed to make it work. I imagine that restarting Stanbol would do the same. Perhaps there is some subtle error in the building of the custom bundle that makes it possible for a Solr index service to be created but not started?
As to managing configuration, you may want to follow: https://issues.apache.org/jira/browse/STANBOL-529 which offers a future way to provide configuration at startup. I'm not familiar enough with the Sling Launcher system to know how difficult it would be to directly expose deployment via REST, but it might be more feasible using the Apache Felix Web Console which is normally included in Stanbol builds: http://felix.apache.org/site/web-console-restful-api.html http://felix.apache.org/site/apache-felix-web-console.html#ApacheFelixWebConsole-RESTfulAPI - --- A.
