Description
Issue #642 contained a list of unimplemented builtin functions but also aggregates. Since they are handled quite differently in the implementation, I put them in a separate issue here. The missing aggregates are:
- `#avg`
- `#GroupConcat`
- `#Sample`
See https://www.w3.org/TR/sparql11-query/#aggregateAlgebra
Contributor guide
Research direction
Start with the linked SPARQL 1.1 aggregate algebra specification, then locate the existing aggregate handling in the Rust code. Confirm the expected behavior for #avg, #GroupConcat, and #Sample and identify the relevant test entry points; done means all three aggregates are supported and covered by tests.
