Clinia’s profiles and relationship definitions let you attach validation rules to every property. These rules complement the built-in type validators described in the base data types and Clinia complex types pages.

​
Rule catalog

The rules array accepts multiple validation criteria:
Validation RuleFormatData Types
requiredboolean (true or false)All fields (including arrays and custom objects)
min & max (on value)integer or decimalNumeric data types
min & max (on length)integerString-based types or arrays
enumMust match property typeNumeric or string-based types
patternRegex stringString-based types
Rules are evaluated in order. You can mix multiple constraints within the same property to achieve stricter contracts.

​
Required fields

Marking a property as required enforces that the key must be present and not null: 
{
  "properties": {
    "propertyName": {
      "type": "symbol",
      "rules": [
        {
          "required": true
        }
      ]
    }
  }
}

​
Numeric data types

integer and decimal properties can enforce value ranges or enumerations: 
{
  "properties": {
    "age": {
      "type": "integer",
      "rules": [
        {
          "required": true,
          "min": 18,
          "max": 120
        }
      ]
    },
    "taxRate": {
      "type": "decimal",
      "rules": [
        {
          "enum": [10.5, 12.2, 15.05]
        }
      ]
    }
  }
}

​
String data types

String-based types (symbol, code, markdown, uri, url, xhtml) can combine length, enumeration, and pattern rules: 
{
  "properties": {
    "comment": {
      "type": "symbol",
      "rules": [
        {
          "min": 5,
          "max": 120
        }
      ]
    },
    "gender": {
      "type": "code",
      "rules": [
        {
          "enum": ["male", "female", "non-binary"]
        }
      ]
    },
    "email": {
      "type": "symbol",
      "rules": [
        {
          "pattern": "^[\\w\\-\\.]+@([\\w-]+\\.)+[\\w-]{2,4}$"
        }
      ]
    }
  }
}
Clinia evaluates regular expressions using the ECMAScript flavor. Escape backslashes accordingly: ^[\\w\\-\\.]+@([\\w-]+\\.)+[\\w-]{2,4}$.

​
Arrays

You can constrain both the array itself and its items: 
{
  "properties": {
    "phones": {
      "type": "array",
      "rules": [
        {
          "required": true,
          "min": 2,
          "max": 10
        }
      ],
      "items": {
        "type": "contactpoint",
        "properties": {
          "value": {
            "rules": [
              {
                "required": true
              }
            ]
          }
        }
      }
    }
  }
}
  • required forces the array to be present (it can still be empty).
  • min/max target the number of elements.
  • Nested rules apply to every item in the array.

​
Objects and complex types

Object properties (custom object types or Clinia complex types like address, contactpoint) only accept required at the top level. To validate sub-fields, apply rules directly on nested properties: 
{
  "properties": {
    "address": {
      "type": "address",
      "rules": [
        { "required": true }
      ],
      "properties": {
        "city": {
          "rules": [
            {
              "pattern": "^[A-Za-z ]+$",
              "required": true
            }
          ]
        }
      }
    }
  }
}
