ContentValidator¶

The ContentValidator checks, if the contents of a message conform to a set of predefined rules. This allows docproc to process only those messages, which are considered functionally valid.

Configuration¶

The ContentValidator requires the following configuration entries:

[contentvalidator-config]
type  = ContentValidator
rules = /path/to/a/rules/set

type: To configure a ContentValidator, use ContentValidator as type.
rules: rules refers to a file on disk containing the rules to be executed on the message content. A rule consists of one or more conditions.

Defining Rules¶

The rules to be executed are kept in a simple JSON-based list.

[
    {
        "name": "First rule",
        "path": "NET",
        "op": "less than",
        "value": 0,
    },
    {
        "name": "Second rule",
        "path": "ZIP",
        "op": "exists",
    }
]

See Operating the Rules Engine for more details about how to configure rules.
