Kevin Chilton updated RYA-260:
------------------------------
Description:
A user must be able to submit a PCJ query that contains the following
aggregation functions from SPARQL:
Sum
Count
Average
Min
Max
This task does not include any aggregations that appear within a GroupBy
clause. We only need to support queries that have the aggregation within the
SELECT section.
For example, the following query should be processed:
{code}
SELECT (avg(?price) as ?averagePrice)
{
urn:BookA urn:price ?price.
}
{code}
And the following query should not be processed because it requires a group by:
SELECT ?title (avg(?price) as ?averagePrice)
{
?title urn:price ?price.
}
GROUP BY ?title
