webgme-json-importer

This repo contains a utilities for importing/exporting models as JSON. The main utility is the JSON Importer which enables a WebGME node to be synchronized with a JSON representation of the target state. This has been primarily used for programmatically creating (and updating) metamodels based off of an external representation. In these cases, the workflow is:

• extract the language specification from the target domain
• transform the specification into the expected JSON representation (documentation available here).
• import the JSON representation into a project. If you first create a node to contain the language elements (conventionally named "Language"), this can be as simple as selecting this node and running the "SetStateFromJSON" plugin).

For examples, check out the examples directory.

Installation

First, install the webgme-json-importer following:

• NodeJS (LTS recommended)
• MongoDB

Second, start mongodb locally by running the mongod executable in your mongodb installation (you may need to create a data directory or set --dbpath).

Then, install dependencies with npm install and start the server with npm start. Finally, navigate to http://localhost:8888 to start using webgme-json-importer!
