cmmn-moddle

Read and write CMMN 1.1 diagram files in NodeJS and the browser.

cmmn-moddle uses the CMMN 1.1 meta-model to validate the input and produce correct CMMN 1.1 XML. The library is built on top of moddle and moddle-xml.

Usage

Get the library via npm package. Bundle it for the web using browserify or webpack.

var CmmnModdle = require('cmmn-moddle');

var moddle = new CmmnModdle();

var xmlStr =
  '<?xml version="1.0" encoding="UTF-8"?>' +
  '<cmmn:definitions xmlns:cmmn="http://www.omg.org/spec/CMMN/20150516/MODEL" id="empty-definitions" targetNamespace="http://bpmn.io/schema/cmmn">' +
  '</cmmn:definitions>';


moddle.fromXML(xmlStr, function(err, definitions) {

  // update id attribute
  definitions.set('id', 'NEW ID');

  // add a root element
  var cmmnCase = moddle.create('cmmn:Case', { id: 'MyCase_1' });
  definitions.get('cases').push(cmmnCase);

  moddle.toXML(definitions, function(err, xmlStrUpdated) {

    // xmlStrUpdated contains new id and the added process

  });

});
