Bonjour,

Je souhaite utiliser jayschema avec node.js pour valider des fichiers json. A l’exécution j'ai une erreur, j'ai regardé les différents exemple mais je ne parviens pas à trouver mon erreur

voici un extrait du code :

	var schemeDatas = require("./datas/calculationSchemes/calculation_schemes.json");
 
	var jsonSchema = {
		"title" : "Calculation scheme",
		"$schema": "http://json-schema.org/draft-04/schema#",
		"type" : "object",
		"required" : [ "name" ],
		"additionalProperties": false,
		"properties" : {
			"name" : { "type" : "string"},
			"description" : { "type" : "string"},
			"nuclides_file" : { "type" : "string"},
			"fissile_rules_file" : { "type" : "string" },
			"structural_rules_file" : { "type" : "string"}
		}
	};
 
	console.log(schemeDatas);
	var validationResult = js.validate(schemeDatas, jsonSchema);
	if(validationResult.length > 0){
		throw ("Validation error :\n" + JSON.stringify(validationResult, null, " "));
	}

	}

Mea-culpa j'avais mal regardé les exemples, il faut en fait utiliser le champ "patternProperties"
