Example

The following command can be used to compare the shape http://example.org/Person in the schemas examples/shex/compare1.shex and examples/shex/compare2.shex:

$ rudof compare --schema1 examples/shex/compare1.shex --format1 shexc --mode1 shex --schema2 examples/shex/compare2.shex --format2 shexc --mode2 shex --shape1 "http://example.org/Person" --shape2 "http://example.org/Person"
Shapes Comparison:
 Equal properties:
  - http://example.org/knows: 
  - descr1:   - value: http://example.org/knows
  - datatype: _

  - descr2:   - value: http://example.org/knows
  - datatype: _


  - http://example.org/name: 
  - descr1:   - value: http://example.org/name
  - datatype: _

  - descr2:   - value: http://example.org/name
  - datatype: _


 Properties in shape 1 that are not in shape 2:
  - http://example.org/worksFor: 
  - descr:   - value: http://example.org/worksFor
  - datatype: _


  - http://example.org/age: 
  - descr:   - value: http://example.org/age
  - datatype: _


 Properties in shape 2 that are not in shape 1:
  - http://example.org/email: 
  - descr:   - value: http://example.org/email
  - datatype: _


  - http://example.org/birthDate: 
  - descr:   - value: http://example.org/birthDate
  - datatype: _

The output of the comparison can be in compact form (by default) or in JSON using the option -r json:

$ rudof compare --schema1 examples/shex/compare1.shex --format1 shexc --mode1 shex --schema2 examples/shex/compare2.shex --format2 shexc --mode2 shex --shape1 "http://example.org/Person" --shape2 "http://example.org/Person" -r json

      }
    },
    "http://example.org/name": {

      }
    }
  },

      "description": {

    "http://example.org/birthDate": {
      "description": {
        "iri_ref": "http://example.org/birthDate"
