OpenConferenceWare is an open source web application for supporting conference-like events. This customizable, general-purpose platform provides proposals, sessions, schedules, tracks, user profiles and more.

By releasing this code under a liberal MIT open source license, we hope to empower other people so they can better organize and participate in more events that support free sharing of information, open society, and involved citizenry.


OpenConferenceWare is distributed as a Rails engine, which means it sits inside a Rails application and adds functionality. While this host application can be built to provide additional parts of your event's website, it will often just serve as a place to configure and customize OpenConferenceWare.


OpenConferenceWare requires Ruby 1.9.3 and a host application built on Rails 4.0.2 or newer.

Starting from scratch

  1. Install the latest version of Rails:

    $ gem install rails -v 4.0.2
  2. Create a new application to host OpenConferenceWare for your event:

    $ rails new sloth_party --skip-bundle
  3. Add 'open_conference_ware' to the newly-created app's Gemfile

    gem "open_conference_ware", "~> 1.0.0.pre"
  4. Run bundle install

  5. Optionally, configure your app's database settings. It's fine to run with the default sqlite configuration, but if you prefer another database, set it up now. OCW is tested with SQLite3, MySQL 5.5, and PostgreSQL 9.3.

  6. Install OpenConferenceWare's configuration files and seed data:

    $ bin/rails generate open_conference_ware:install

    If you want OCW to be mounted somewhere other than the root of the application, you can pass a mount point to the generator, like so:

    $ bin/rails generate open_conference_ware:install /ocw
  7. Edit config/initializers/01_open_conference_ware.rb and config/secrets.yml to configure OCW's settings. You'll find comments in these files explaining the available options.

  8. All of these newly-generated files, except config/secrets.yml, should be added to your version control system. If you're using git, you may want to add config/secrets.yml to your .gitignore, to ensure it doesn't get shared accidentally.

  9. At this point, you should be able to fire up a server and see OpenConferenceWare at http://localhost:3000

    $ bin/rails server


OpenConferenceWare uses OmniAuth to allow users to sign in using a variety of external services. No authentication method is enabled by default, so you'll need to configure one before deploying OCW.

To do this, just add the gem for the desired provider to your Gemfile, run bundle install, and configure it in config/initializers/02_omniauth.rb.

For example, to enable sign-in with Persona, you would add the omniauth-persona gem to your Gemfile

gem 'omniauth-persona'

and add the provider to 02_omniauth.rb

provider :persona

Sign In Forms

Friendly sign-in forms are provided for OpenID and Persona, but it's easy to add your own. After enabling an OmniAuth provider, create a partial view at app/views/open_conference_ware/authentications/_provider_name.html.erb, where provider_name is the name passed to the provider method in the initializer.


Feature Flags

Many features of OCW can be enabled or disabled to meet your event's needs. These can be toggled by editing flags in config/initializers/01_open_conference_ware.rb.

Views and Styles

Since OpenConferenceWare is an engine, all of its views are packaged inside the gem. To customize things, you can easily override any view by creating one with the same name in your application.

To simplify this process, we've included a generator that will copy views out of the gem for you. Invoking the following command will copy all of OpenConferenceWare's views:

$ bin/rails generate open_conference_ware:views

If you only need to override a particular set of views, you can pass arguments to the generator to narrow things down. This will copy only the layout file and view related to rooms:

$ bin/rails generate open_conference_ware:views layouts rooms

You can see a full list of available arguments by running:

$ bin/rails generate open_conference_ware:views --help


Both GitHub's releases page and provide a summary of significant changes made between releases. If you are running a fork of this software, please carefully read these changes to avoid surprises when you pull the updates into your fork.

Old Versions

Prior to version 1.0, OpenConferenceWare was distributed as a standalone Rails application. Those releases are tagged with version numbers, such as v0.20090416, which represent the date they were made. The final release to be distributed this was was v0.20131209, which is based on Rails 3.2.



Some features of OCW may not be immediately evident as a new user. We will attempt to shed light on them here.

Selection Committee Voting

OCW allows you to designate members of a content selection committee, who can then view feedback from the public and vote on sessions for inclusion in your conference. In order to enable this:

  1. An admin needs to edit users to grant them selection committee privileges.
  2. An admin needs to edit the event to accept selector votes.
  3. Selection committee members will then see a voting interface on proposal pages and a "selector votes" overview.
