> Construct Query Support for Rya Fluo
> ------------------------------------
>
> Key: RYA-273
> URL: https://issues.apache.org/jira/browse/RYA-273
> Project: Rya
> Issue Type: New Feature
> Affects Versions: 3.2.10
> Reporter: Caleb Meier
> Assignee: Caleb Meier
>
> Add support for Construct Queries to the Rya Fluo Application. This will
> require implementing ConstructQueryMetadata for Fluo and creating the
> appropriate observer to generate the statements indicated by the construct
> query. See the documentation for creating a new query node for Fluo:
> https://github.com/meiercaleb/incubator-rya/tree/periodic_query_service/extras/rya.pcj.fluo
