OntoUML JS

Javascript library utility for manipulating OntoUML models.

Getting Start

npm install ontouml-js --save

// yarn users
yarn add ontouml-js

Usage

This package is designed to support manipulating OntoUML models and their serialization into ontouml-schema compliant JSON files.

import { Project, serializationUtils } from 'ontouml-js';

// Every OntoUML element can be created from a constructor that can receive a partial object as references for its creation
const project = new Project({ name: 'My Project' }); // creates an OntoUML projects

// Projects contain an instance of Package  dubbed model that contains all model elements in the project
// Container elements, e.g., projects and packages, also serve as factories for their contents
const model = project.createModel({ name: 'Model a.k.a. Root Package' }); // creates a "model" Package

// Instead of partial objects, "factory" methods receive more suitable lists of arguments to facilitating populating elements
const person = model.createKind('Person');
const school = model.createKind('School');
const date = model.createDatatype('Date');
const enrollment = model.createRelator('Enrollment');
const studiesAt = model.createMaterialRelation(person, school, 'studies at');

model.createMediationRelation(enrollment, person);
model.createMediationRelation(enrollment, school);

// our API is constantly updated to include helpful methods to facilitate building OntoUML models
studiesAt.getTargetEnd().name = 'school';
studiesAt.getTargetEnd().setCardinalityToMany();
studiesAt.getSourceEnd().name = 'student';
studiesAt.getSourceEnd().cardinality = '1..*';

enrollment.createAttribute(date, 'enrollment date');

// Containers also include methods to easily support retrieving their contents
model.getAllAttributes(); // returns all contained attributes
model.getAllClasses(); // returns all contained classes
model.getAllGeneralizations(); // returns all contained generalizations

// Any element can be easily serialized into JSON, and properly serialized elements can be deserialized just as easily
const projectSerialization = JSON.stringify(project);
const projectCopy = serializationUtils.parse(projectSerialization);
