XWiki @ Google Summer of Code 2014

Last modified by Sergiu Dumitriu on 2014/02/24 21:07

Unfortunately, XWiki will not take part in Google Summer of Code 2014 as a mentoring organization. However, if you like one of the projects proposed on this page and you would like to contribute, don't hesitate to contact us on the mailing list or the IRC channel.

This page hosts information and project ideas for the open source project XWiki related to the Google Summer of Code 2014 mentorship program.

About GSoC

You can learn a lot about the program by reading the GSoC FAQ. The timeline of this year's edition is given here.

XWiki Guidelines

Being part of the XWiki community means knowing our rules and practices. As a GSOC student you need to make sure you read and apply our guidelines. 

Student Application template

When applying for one of our projects, please provide this information about yourself and the project you choose in the application which you submit to Google.

Proposed Projects (11)

Students can come up with their own ideas, but the ideas need to be proposed and discussed on the mailing list.

As of now, we're still in a brainstorming phase and the projects proposed below are just wild ideas at this stage. We encourage everyone to propose ideas or even to revive old ideas from the previous years. Then we'll have a community vote later on to decide which ones we are interested in for GSoC 2014. Students will then be able to pick from these selected projects, discuss them with us or even propose other subjects. We also recommend students interested in joining XWiki for GSoC 2014 to manifest themselves as early as possible so that we can start working with them on this project list.

Add support for the AsciiDoc syntax

The idea is to add AsciiDoc support to XWiki Rendering (see the current list of supported syntaxes).

The rationale is that AsciiDoc is very popular nowadays and very nice for writing documentation.

See Extending XWiki Rendering.

Any Integration with one or more Major Open Source Tool

We would love to see integration with other Open Source Tools. These integrations could be brining data and interaction of the other tool in XWiki or the opposite.

This project leaves the student to propose which integration he would like to work on.

Estimated workload: 3 month. Read more...

DokuWiki importer

WikiStream framework allows converting from one wiki representation to another. The idea here is to provide a WikiStream input module for MediaWiki so that it's possible to convert from MediaWiki to any WikiStream output format.

You can get inspiration from http://extensions.xwiki.org/xwiki/bin/view/Extension/Import+DokuWiki+into+XWiki+Application and http://extensions.xwiki.org/xwiki/bin/view/Extension/Dokuwiki+To+XWiki2+Extension.

Git/GitHub application

There are already several extensions that deal with git: a module that allows to perform operations on a git repository from the wiki, a small GitHub stub that allows to list committers for an organization or a project, and a more complex application that allows to synchronize wiki pages with a repository on GitHub. The goal of this project is to provide a richer integration with git:

  • a space in the wiki can be linked to a repository on GitHub (or any other git repository)
  • display in the wiki active pull requests and their status (when using a GitHub repository)
  • insert custom events in the Activity Stream for new commits, pull requests, comments on commits, new/deleted branches or tags...
  • code and committers statistics
  • list commits, linking user names to users in the wiki, and issue numbers to the corresponding Jira issue

Another direction is enhancing the GitHub Commit Application:

  • better UI
  • better handling of merges
  • support for selective commits (like git add --interactive)
  • better support for user configuration

Improve Extension Repository

XWiki provide an extensions repository for anyone to easily deploy contributions. See http://extensions.xwiki.org.

The goal of this GSOC is to improve it. The student will have to study it and propose improvements, there is no definite list of things to do.

Here are some ideas: Repository open Jira issues.

Improve l10n.xwiki.org

XWiki community maintain a wiki with a special application to help translation XWiki projects on. See http://l10n.xwiki.org. Sources can be found on https://github.com/xwiki-contrib/application-l10n.

The goal of this GSOC is to improve it. The student will have to study it and propose improvements, there is no definite list of things to do.

Various ideas:

  • make all this a lot more dynamic
  • provide tools to refactor things a bit:
    • it's hard to move some translation from one space to another (for example the applicationresources on XE should be on Platform)

etc.

MediaWiki importer

WikiStream framework allows converting from one wiki representation to another. The idea here is to provide a WikiStream input module for MediaWiki so that it's possible to convert from MediaWiki to any WikiStream output format.

The best is probably to convert https://github.com/xwiki-contrib/sandbox/tree/master/xwiki-wikiimporter/xwiki-wikiimporter-mediawiki-xml into a WikiStream module and improve it.

More extension repositories

Right now XWiki Extension Manager support plain Maven and XWiki Extension (http://extensions.xwiki.org) repositories.

The idea is to add support for as much other kind of repositories as possible.

Here are some good examples:

  • Nexus
  • Bintray
  • Pypi

See http://dev.xwiki.org/xwiki/bin/view/Design/ExtensionManagerRepositories for more details.

Translation in context

XWiki 4.4 introduce new translation macro which will allow to find easily translated content in a page when using annotated XHTML renderer.

The idea is to use that and provide a "translation mode" where you can directly select and translate what you see in the page (when the translation macro is used). The idea is also to make easy to contribute to http://l10n.xwiki.org from your local wiki by sending your corrections to it.

Various ideas for the look and feel of this feature:

XCLAMS: Federated Servers

The XWiki Collaborative Learning Assets Management System is used in several projects of sharing platforms for learning content, among others: curriki.org, i2geo.net, and planete.sankore.org.

The project's work is to implement web-based tools in these platforms so that content in one platform can be made visible in another. Differently than federated search, the objective is to allow an easy transport of a resource from one server to another where it starts a new life while it keeps a link to the original. In open-source parlance, this gives birth to a fork. That transport should be initiated by a function triggered by a user who thinks it is useful to copy to bring the resource closer to him/her or a group where he/she is a member.

Ideally, the tool should scale to support administrators that transport complete collections (as much as 1000) of selected learning resources.
Moreover, the link to the original should be kept and displayed and it should be possible for a user to request an upgrade of the transported resource if the source has been updated and if compatible. The practice of versionning systems such as git or mercurial should be a model. The project would be very successful if it can employ the 3-way-merge facilities of the underlying XWiki to this process, making it possible to work in parallel.

Such a contribution is likely to support such initiatives as the build of a local copy of Curriki with selected content which can serve a local community of teachers (the Curriki team has been asked for such by governments of countries with a relatively limited external internet bandwidth such as pacific islands). Moreover, this contribution should be created in a sufficiently generic way so that any XWiki installation that has the necessary XWiki objects to transport the learning resources can exploit it.

Mentors: the XCLAMS community, including Paul Libbrecht and Bob Greenawalt (confirmed), as well as Joshua Marks, Ludovic Dubost and Flavius Olaru.

Discussion: is to happen on the XCLAMS and xwiki-devs mailing-lists as well as on the #xclams and #xwiki IRC channels. We welcome students' questions there!

Delivery: open-source code (LGPL) using Groovy, and Velocity that can be made part of the XCLAMS core code. Possibly Java code too.

ePub Publisher

The tool proposed here is to provide a shell to publish ePub archives that work on mobile devices. The objective is to export assemblies of pages within an ePub book that can be enjoyed offline on devices following identified profiles.

In particular the XWiki Collaborative Learning Assets Management System, an OER sharing platform in use by several projects, supports the assembly of learning resources of diverse origins and types by a concept of collections which encourages re-usability. This project should enhance this re-usability by an export feature that allows the content of a collection to be exported as e-book.

The software should support the author in predicting and verifying the playability of the content on various devices (e.g. warning that a Flash file is not going to work on the profile Aldiko on Android). It should also leverage open-source softwares such as Swify, ImageMagick, of ffmpeg to ensure an embedding that is reasonable in size and that works in typical mobile devices. An environment for prototyping the delivered ePub is central to this work. The delivery is likely to base on the recently launched Curriki Geometry tablet oriented interface.

The Curriki and Planète Sankoré teams, together with the trainee, will support this choice in suggesting environments in wide use in their target population where this can be tested in the timeframe of the project (schools in the US, India, France, and the French speaking Africa).

A very successful contribution would include code that we can deploy to any XCLAMS installation. It should, with a small amount of changes, allow developers to also export to other package formats such as SCORM or Common Cartridge and maybe even deliver Android's APK applications.

Mentors: the XCLAMS community, including Paul Libbrecht and Bob Greenawalt (confirmed), as well as Joshua Marks, Ludovic Dubost and Flavius Olaru.

Discussion: is to happen on the XCLAMS and xwiki-devs mailing-lists as well as on the #xclams and #xwiki IRC channels.

Delivery: open-source code (LGPL) using Groovy, Velocity, Unix command-line-tools, that can be made part of the XCLAMS core code.
