[jira] [Updated] (ARIA-119) Syntax for executing a relationship operation on a specific edge (source/target)

     [ https://issues.apache.org/jira/browse/ARIA-119?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ran Ziv updated ARIA-119:
-------------------------
    Description: 
TOSCA doesn't define a syntax for specifying which edge (source/target) of the relationship a relationship operation should run on. At the moment, this will be determined by the workflow author.
We could provided a syntax where the `implementation` field value would also hold the information for the edge, e.g.:

{{implementation: script.sh @ SOURCE}}

SOURCE and TARGET are already familiar "TOSCA constants", and the implementation field already has special syntax using the "@" sign so this seems to make the most sense.
