From CNM Wiki
Jump to: navigation, search

Opplet (historically known as CNM Cloud) is the information technology that powers CNMCyber.

Opplet (Russian: Оплёт; hereinafter, the Software) is the middleware that enables CNM Cloud. The Software runs on CNM Farms and particularly includes user management software and event management software, which are integrated through API with authorization and authentication systems.

Core interfaces

User interface

Main wikipage: Opplet.net
Opplet.net is the Software's user interface (UI) that is supported by CNM Cloud.

Application interface

An OpenLDAP instance is used as the core application interface.

Special plug-ins

Several software plug-ins have been written specifically for the Software.

Moodle-to-Opplet (Moodle side)

A software plug-in is written specifically for CNM Moodle to transfer course completion data from CNM Moodle to the Software.

Moodle-to-Opplet (Opplet side)

A software plug-in is written specifically for the Software to process data taken from CNM Moodle and add to or delete from a group in the Software and, consequently, its OpenLDAP instance.

Opplet-to-Wikiware (Opplet side)

A software plug-in is written specifically for the OpenLDAP instance to connect it to those versions of MediaWiki starting with version 1.27 that are used in CNM MediaWiki.

Opplet-to-Wikiware (wikiware API side)

A software plug-in is written specifically for the Software to transfer data to API of CNM MediaWiki to change user rights.

Wikiware API

A software plug-in is written specifically for CNM MediaWiki to provide it with API that will allow the Software changing user rights in CNM MediaWiki such as add to a group, remove from the group, etc.

OpenStack (future extension)

The Software shall be integrated with the native OpenStack Keystone authorization system of OpenStack using the output on the LDAP protocol.

Keystone is an OpenStack's Identity API. It supports LDAP, OAuth, OpenID Connect, SAML and SQL. ... [Keystone] does not actually implement any user-management functions; rather, it provides plug-in interfaces so that organizations can leverage their current authentication services.


Support for workforce

The Cloud is designed to support people who:
  1. Haven't identified their vocations and/or profession yet. For these people, the Cloud can be helpful as a tool for organizing review seminars, practices and studies for them;
  2. Have identified their vocation and profession, but lack of employable credentials. For these people, the Cloud can be helpful as a tool for training, on-the-job training or certification of skills;
  3. Have identified their vocation and profession, as well as possessed all employable credentials, and are looking for a specific job. For these people, the Cloud can be helpful as a tool for job search skills building, market information, contacts, and marketing channels.

Secondary objectives

In addition, the Cloud can be useful:
  • Those graduates who decide to organize or promote their own enterprises,
  • Those enterprises that source, selects, hires, onboards, and/or develops their workforce using the Cloud.

Services (CNMCyber) and apps

The Cloud currently hosts services, which are collectively known as CNMCyber, every of which is supported by one CNM app.
