YARRRML conditions on objects are not correctly processed about morph-kgc HOT 3 CLOSED

Hi @david-martinez-garcia,

Morph-KGC does not currently support that YARRRML syntax. However, you can do it by using the following:

prefixes:
 ex: "http://example.com/"
 grel: "http://users.ugent.be/~bjdmeest/function/grel.ttl#"
 idlab-fn: "http://example.com/idlab/function/"

mappings:
  person:
    sources:
      - access: data.json
        referenceFormulation: jsonpath
        iterator: $.persons[*]
    s: http://example.com/$(firstname)
    po:
      - [a, foaf:Person]
      - [ex:name, $(firstname)]
      - p: ex:is_smith
        o:
          - f: grel:controls_if
            datatype: xsd:boolean
            parameters:
              - [grel:bool_b, "'Smith' == '$(lastname)'"]
              - [grel:any_true, "true"]
              - [grel:any_false, "false"]

Thanks for your help @arenas-guerrero-julian. Your solution is even simpler and more elegant than mine. I have tested it and it works perfectly fine. I would have used it from the beginning but it's hard to find documentation and examples on how to use grel functions in YARRRML.

CC: @idomingu and @LuciaCabanillasRodriguez maybe this is of interest to you (based on a question you posted on slack)
