Unknown body atom type: EQUALITY_PROPERTY_ASSERTION

[harshal patni]

Hi Everyone,

        I am trying to execute this rule below. The rule is added to my graph and I am trying to execute using the following command - 

./stardog query "mmi;reasoning=SL" "select ?x ?y where {?x <http://www.motivemi.com/ontologies/2014/09/mmi.owl#matches> ?y}"

I am getting the Unknown body atom type: EQUALITY_PROPERTY_ASSERTION. 

Can someone guide me on whats wrong here?

Rule ----------------------------------------

@prefix rule: <tag:stardog:api:rule:> .

[] a rule:SPARQLRule ;

rule:content """

    FILTER (?u1 = ?u2)

}

THEN 

{

  ?e mmi:matches ?o .

Can you provide the data that causes that message when combined with the aforementioned query?

Thanks.
