Hi [~jomarko]

The "Relation editor" is [here|https://github.com/manstis/kie-wb-common/tree/GUVNOR-3397/kie-wb-common-dmn/kie-wb-common-dmn-client/src/main/java/org/kie/workbench/common/dmn/client/editors/expressions/types/relation].

You can download the DMN Specification from [here|http://www.omg.org/spec/DMN/1.1/PDF] page 103 covers "Relations". They are basically a simple grid of key/values where the key is the name of a {{InformationItem}} and the value is a {{LiteralExpression}}. The underlying DMN object model supports any type of expression by [~tirelli] has stated it is sufficient to only support {{LiteralExpressions}}. FYI our code can support any type of expression however the Relation Editor has been limited to {{LiteralExpression}}.
