We've been hard at work on Wikimedia Commons Query Service (WCQS) [2]. This will be a SPARL endpoint similar to WDQS, but serving the Structured Data on Commons dataset. Our goal is to open a beta service, hosted on Wikimedia Cloud Service (WMCS) by the end of July. The service will require an account on Commons for authentication and will allow federation with WDQS. We don't have a streaming update process ready yet, the data will be reloaded from Commons dumps weekly for a start.
