Semantic Wiki

This wiki has been extended with Semantic Wiki, see [1] for the user manual. A brief introduction is available from Help:Using semantics

From the FAQ:

  • How to refresh a page; Add "&action=purge".


The ParserFunction extension allows you 'program' Page content to some extent. See [online ParserFunctions Help] for its options.

PDF handler

PDF Handler allows previews of uploaded pdf files. See also Help:Add Image from upload.

File Upload

When editing a Page you get the opportunity to upload files. Courtesy of MsUpload].

See Help:Add Image from upload for an example.

Html5 media player

Html5media embed video's and the like

See Help:Embed video for an example


Module has been disabled -- BUT read this

We are considering an alternative solution using a local -- on the server that is -- subversion working directory and possibly automatically upload parts of it using pywikibot. However is looks that pywikibot triggers errors: PHP Fatal error: Base lambda function for closure not found .

In the mean time a local copy of the /svn/sega/pub repository is available as /var/svn/pub. A script to synchronise the repository and the working copy can be issued through the staff pages: svnupdate (staff only).

Obsolete part We use SVN for binary data repository. Images etc are stored and maintained in our local Subversion repository. See Help:Add Image from SVN repository for the use of images through svn.

Simple Security: Lockdown

We installed [2] an extension to mediawiki to control access to certain Namespace.

See Help:Restrict access for more information.

Getting started:

Using this SeGa webserver and its services

The SeGa server runs Debian distribution, using apache 2 as a webserver; what else? Here are some included services


A limited set of directories support h264 streaming through the h264-streaming mod. H264 streaming requires h264 encoding.


No luck yet in creating a working script under Debian stable for h264 transcoding. ffmpeg on Debian stable lacks h264 encoder support. It has x264, but piping is awkward.


On a Mac OSX system consider using the open source tool: [HandBrake]

We had some success using:

  • video codec: h264 (x264)
  • fps: as source
  • size: 854 x 480
  • avg. bitrate: 960
  • 2 pass encoding
  • x264 preset: medium
