About me

Clarification

I am a graduate student in computer science at the Hebrew University in Jerusalem. I am interested in wikis and in other methods of thinking, discussion, knowledge management, and creating ideas by groupthink. I started working with Wikis as an undergraduate student when I built a site for my debate club in Tel Aviv. In the last six years I continued to study and programmed in MediaWiki, but at low intensity, due to more pressing obligations. Only in 2012 I managed to make time to really learn deeply on wikis. But I wasted a lot of my time for development on a branch that was abandoned at the end: SMW +. I guess that's part of the risk of contributing to an open source product. Fortunately I heard that now there is an initiative to reuse at least some of the capabilities developed for the SMW+. Perhaps not all is lost. But some of my code is available as an independent extension. And you can contact me via email and ask for help or for more extensionsץ

Feel free to contact me with any questions by email Mail: orbartal+wikimediagmail.com

This page and my activities in MediaWiki represent me alone, and are preform voluntary on my free time. They are in no way represent my current (or any previous) employer or any other governmental, academic or business organization where I was or will belong to in the future, unless explicitly stated otherwise.

Also even though I try to help as best as I could, and check the correctness of my words and the integrity of the code I write, I provide my code and advice with no obligation, not even for best efforts, unless explicitly stated otherwise. And of course all the code I post here is open source under the GPL.

Some of my code contributions to MediaWiki

Any file type gets its own Tag in extension: page schema https://gerrit.wikimedia.org/r/#/c/77896/
ReorderParserPhases http://www.mediawiki.org/wiki/Special:ExtensionDistributor/ReorderParserPhases, https://www.mediawiki.org/wiki/Extension:ReorderParserPhases
Fix bug Can't upload file with non-ASCII name (eg cyrillic) on Windows host https://bugzilla.wikimedia.org/show_bug.cgi?id=1780
How to Localization SMW+ Manual, and a translation of the interface and terminology into Hebrew.

Unfortunately the company went bankrupt shortly after I sent them the translation. Although the product continues under a different company, but I Can not guarantee the manual is true for the newer versions of SMW+. Anyway anyone interested in SMW+ is welcome to consult with me.

What is the Semantic web

As usual the best explanation is in Wikipedia

Wikipedia page also contains links to many articles and sites are explained in depth the concepts related to the Web 3.0 and semantic web. But if you want to understand it more quickly, you should watch some of the short videos I collected, that explain the issue in less than 5 minutes.

Client case study: The USA government

After 9/11 in an Attempt to improve the knowledge management inside it’s intelligence organizations the U.S. government began to use software for creating websites Wikimedia management and knowledge sharing among employees of various intelligence agencies.

Everybody is using wiki:

Who is using wiki, and for what.

United States Intelligence Community - Intellipedia

United States Department of State – Diplopedia

United States Department of Defense - DoDTechipedia

As you can learn from this video, the wiki and the web increase intelligent capabilities.

And some more examples…

And for that purpose it even sends it agents to special courses on how to use Web 2.0.

It also increase its information security, and help it to avoid the next wikileak (despite the names similarity wikileaks and mediawiki have nothing in common). According to interviews with senior Foreign Ministry:

Intellipedia

Interview tube with Intellipedia initiators, or in youtube

Interesting designs (skins) for MediaWiki

The skin (design) determines the appearance of the wiki, the menus and shortcuts that appear around each page. The Wikipedia skin, MonoBook, is the most famous skin, but far from been the only skin, or even the most beautiful useful skin. In here there are links to many examples of wikis with different skin (designs from all around the web:

Sites that are using original skins

A French Children wiki, that look and feel like an iPhone app.

Wiki revolution in our lives

http://www.slideshare.net/LLudwig/what-is-artificial-memory - Imagine a world where every word and phrase that is said or written is attached to its dictionary definition link (or any other definition the speaker chose to give it the context of the court when he said the word). No more misunderstandings or deliberate evasions, the exact meaning of what is being said. Just think how this will affect the promises of politicians before the election. Link To the memory manifesto.pdf manifest file.

Hierarchical File Systems are dead - File management as performed today on pc is perhaps fit to computer software and hard drives capabilities and users’ needs as they were 20 years ago. But are misfit to today abilities and needs, in the era of the global internet and user friendly interfaces. Today we still use the old hierarchical arrangement of files and folders. Each file is contained by only one folder, which itself is contained in only one folder, etc… so each file as a single path to it.

In the future we shell manage every hard drive with a browser and database software. Each file will have a unique url inside the computer (End to broken Links after a file was moved to another folder or a folder name in its path was changed) and the same file will belong to many hierarchies. Similar to pages and categories in a wiki site.

It will also improve search and file management. And of course, no more duplicate files on your computer, and any file will have its complete edit history, and several users could work on the same file from different account at the same time, like in a version control software (svn, git)..

It so clear that we need it, and so easy to implement, that it is not clear what take it so long to be the default choice in file management?
