The same question written in every language. In every example self is an ArchiMate element, and in SPARQL it is ?self.

Does the element carry a name

Language	Expression
AQL	self.name <> null and self.name.trim().size() > 0
OCL	self.name <> null and self.name.size() > 0
EOL	self.name.isDefined() and self.name.trim() <> ''
CEL	self.name != ""
SPARQL	ASK { ?self archimate:Nameable.name ?name .      FILTER(STRLEN(STR(?name)) > 0) }

Is the element connected to anything

Language	Expression
AQL	self.incomingRelationships->notEmpty() or self.outgoingRelationships->notEmpty()
OCL	self.incomingRelationships->notEmpty() or self.outgoingRelationships->notEmpty()
EOL	not self.incomingRelationships.isEmpty() or not self.outgoingRelationships.isEmpty()
CEL	self.incomingRelationships.size() > 0 || self.outgoingRelationships.size() > 0
SPARQL	ASK {   { ?r archimate:ArchimateRelationship.source ?self }   UNION   { ?r archimate:ArchimateRelationship.target ?self } }

The names of everything the element points at

Language	Expression
AQL	self.outgoingRelationships->collect(r | r.target.name)
OCL	self.outgoingRelationships->collect(r | r.target.name)
EOL	self.outgoingRelationships.collect(r | r.target.name)
CEL	self.outgoingRelationships.map(r, r.target.name)
SPARQL	SELECT ?name WHERE {   ?r archimate:ArchimateRelationship.source ?self ;      archimate:ArchimateRelationship.target ?target .   ?target archimate:Nameable.name ?name . }

Collection operations are written with -> in AQL and OCL, with a dot in EOL, and as macros in CEL; SPARQL returns rows instead of a collection.

Is the owner property set exactly once

Language	Expression
AQL	self.properties->select(p | p.key = 'owner')->size() = 1
OCL	self.properties->select(p | p.key = 'owner')->size() = 1
EOL	self.properties.select(p | p.key = 'owner').size() = 1
CEL	self.properties.exists_one(p, p.key == "owner")
SPARQL	ASK {   { SELECT (COUNT(?p) AS ?owners) WHERE {       ?self archimate:Properties.properties ?p .       ?p archimate:Property.key "owner" .   } }   FILTER(?owners = 1) }

Note the equality operators: = in AQL, OCL and EOL, == in CEL, and a pattern match in SPARQL.

Trim a stray space out of the name

Only two languages change a model, so this task has two answers.

Language	Expression
EOL	self.name = self.name.trim();
SPARQL	DELETE { GRAPH ?g { ?self archimate:Nameable.name ?name } } INSERT { GRAPH ?g { ?self archimate:Nameable.name ?trimmed } } WHERE { GRAPH ?g { ?self archimate:Nameable.name ?name }          BIND(REPLACE(REPLACE(STR(?name), "^\\s+", ""),                      "\\s+$", "") AS ?trimmed) }

In the update, ?g is bound to the graph of the model along with ?self.

The same body written in AQL, OCL or CEL is rejected where a change is required, and never touches the model where it is accepted.
