What is your question?

Given the If/Then/Else example (below for reference), if animal was an array, how could I write conditional logic to check if "Cat" appears in animal (as opposed to strict equality)?

{
  "type": "object",
  "properties": {
    "animal": {
      "enum": [
        "Cat",
        "Fish"
      ]
    }
  },
  "allOf": [
    {
      "if": {
        "properties": {
          "animal": {
            "const": "Cat"
          }
        }
      },
      "then": {
        "properties": {
          "food": {
            "type": "string",
            "enum": [
              "meat",
              "grass",
              "fish"
            ]
          }
        },
        "required": [
          "food"
        ]
      }
    },
    {
      "if": {
        "properties": {
          "animal": {
            "const": "Fish"
          }
        }
      },
      "then": {
        "properties": {
          "food": {
            "type": "string",
            "enum": [
              "insect",
              "worms"
            ]
          },
          "water": {
            "type": "string",
            "enum": [
              "lake",
              "sea"
            ]
          }
        },
        "required": [
          "food",
          "water"
        ]
      }
    },
    {
      "required": [
        "animal"
      ]
    }
  ]
}

Hi @zmsmith,
If you want to check whether a value is in the array, instead of:

"if": {
        "properties": {
          "animal": {
            "const": "Cat"
          }
        }
      }

you should say:

"if": {
                "properties": {
                  "animal": {
                    "contains": {
                      "const": "Cat"
                    }
                  }
                }
              }
