ISSUE-24: Clarify support for complex joinConditions

Complex joinConditions

Clarify support for complex joinConditions

State:

CLOSED

Product:

R2RML

Raised by:

David McNeil

Opened on:

2011-03-01

Description:

I suggest adding text to the R2RML specification to clarify what is allowed in joinConditions. This should address for example, the use of compound join conditions (e.g. {child}.x = {parent}.x AND {child}.y = {parent}.y) as well as the use of SQL functions and operators in the expressions.
