--------------------------------
Resolution: Done
> Provide machinery for syntax manipulation
> -----------------------------------------
>
> Key: JENA-976
> URL: https://issues.apache.org/jira/browse/JENA-976
> Project: Apache Jena
> Issue Type: Improvement
> Components: ARQ
> Reporter: Andy Seaborne
> Assignee: Andy Seaborne
> Fix For: Jena 3.0.0
>
>
> Jena ARQ does a lot of algebra manipulation (for example, the high level
> optimizer is a collection of algebra transformation rules).
> Sometimes, manipulation of query syntax is needed. Examples include rewriting
> a query with a specific variable replaced by a constant term, or simplying
> syntax after applying {{OpAsQuery}} (for safety, it adds some additonal "{ }"
> around query parts and these can only be removed in-context; that means a
> pass over a built query to detect and improve the syntax tree.
> This task is to add a framework for query syntax manipulation.
