Introduction

GridCalendar is a community website where the public and private groups can share information about interesting events. It has a strong focus on scientific and  FOSS-related conferences, using  Free Software, and  Free Data, and  Free Formats.

In the past we used the name CloudCalendar (abbreviated as cloca.net)

Creators

This project has been initiated by  Ivan Villanueva,  Mario Behling and  Sven Guckes (alphabetic order).

Goals

Basically, we created this project because we want to be able to share events information and manage them within our calendars, communities and the world. Hopefully many others will colaborate. The main features are:

  • Community oriented:
    • Everyone can create and update events
    • Everyone can comment and tag events.
    • Users can set filters to get notified of interested events to them
    • Users can create private groups
  • Free content: Except for the data of private events and groups, all content is free.
  • Free documentation: We documents other calendar sites and our design decisions to ensure reuse of the data and experience.
  • Openness: All public data can be downloaded easily in several formats.
  • Formats and Interoperability: We use free and open formats whereever possible, and we try to support conversion between formats, too.
  • Diversity: There are several means for input and output to accomodate as many people as possible.
  • License: The license of the software is "free" as in  Affero General Public License. The license of the public data is "free" as in the  Creative Commons Licences
  • Internationalisation: We aim to be multilingual.

Organisation

Once this project is in a more advanced state, setting up an organisation will be necessary.

Ivan suggests a German Limited ( haftungsbeschr?nkt), which can also be for the public interest ( Gemeinn?tzigkeit). See also  Gesellschaft.

Timeline

  • 2010-02-23: As the code is almost in an usable state, Ivan registered in Berlin a preliminary business for setting up the German Limited.

Trac

We use for a start the free software  Trac for this wiki, tracking system, etc.

Trac is a minimalistic approach to web-based management of software projects. Its goal is to simplify effective tracking and handling of software issues, enhancements and overall progress.

To use Trac with Vim, see  http://www.vim.org/scripts/script.php?script_id=2147

All aspects of Trac have been designed with the single goal to help developers write great software while staying out of the way and imposing as little as possible on a team's established process and culture.

As all Wiki pages, this page is editable, this means that you can modify the contents of this page simply by using your web-browser. Simply click on the "Edit this page" link at the bottom of the page. WikiFormatting will give you a detailed description of available Wiki formatting commands.

"trac-admin yourenvdir initenv" created a new Trac environment, containing a default set of wiki pages and some sample data. This newly created environment also contains documentation to help you get started with your project.

You can use trac-admin to configure  Trac to better fit your project, especially in regard to components, versions and milestones.

TracGuide is a good place to start.
