SEE DEMO HERE

Installation

Download the latest release XML and import it into iKnow-enabled namespace (for example, SAMPLES). Then, open your browser at http://127.0.0.1:57772/EntityBrowser/ web page (change the host/port respectively to your server's addresses and always append the trailing slash / at the end of the URL).

To delete the application, simply delete the EntityBrowser package, the web application will be deleted automatically if it wasn't modified since installation as well as it gets created during the installation.

Currently, to use iKnowEntityBrowser in different namespaces, you need to import the project to each iKnow-enabled namespace, and manually set up web application (for example, you can clone /EntityBrowser application and name it /EntityBrowserUser). Change the settings inside application as well in this case. Currently we are working under possibility to change the namespace from the UI interface.

If you installed iKnow Entity Browser on the server and made the web application public, you can connect to this server from any front-end, for example, even from this demo application.

• Reset the selection with reset selection button.

Settings and Embedding

You can change different settings to control application behavior. All settings are stored in browser's local storage. Also, you can overwrite any option by passing its name and a value as an URL parameter (make sure all URL parameters are properly encoded). The list of supported options is represented in the table below.

URL Parameter	Default	Description

Development

Development requires Node.JS (v4.0.0-7.5.0+) (but may work on previous versions as well), Git and Caché 2016.2+ to be installed.

Development of the project lies completely outside of Caché (in any environment you like). The project tree has three main entry points:

1. Static client files at src/static. This is the front-end part of the application which will be packed by Gulp and put to StaticData.cls class.
2. Server package at src/cls. It contains all Caché classes in UDL format. The directory structure inside src/cls directory corresponds to the package structure in Caché.
3. Import scripts that make the development like a charm: set up once and use one command to import/export project to/from Caché.

There are some steps needed for initial setup:

git clone https://github.com/intersystems-ru/iknow-entity-browser
cd iknow-entity-browser
npm install

Then, edit Pre-configured variables section in import.* script to match your system. Now you're ready! Run the following:

import                              # or ./import on *nix systems

This will build the project and put all classes into your Caché. Also, this will export XML file that can be imported to any Caché system (2016.2+).
