Global templates/Proposed specification, short version/ja

Wikimedia projects have a problem. The software on them is a mix of code that comes from two sources:


 * 1) Deployed software: MediaWiki core and its extensions, which are developed, deployed, and internationalized centrally through,  and related tools.
 * 2) Local customizations: A large collection of on-wiki tools that are developed locally on each wiki site:, , and.

For the editors and the readers of the sites, the different technologies mesh together and appear as one product, but the different software development process also poses some challenges:


 * The local customizations can often be useful in many languages, but porting them between wikis and languages is extremely hard and time-consuming.
 * Software features such as and  cannot be aware of such local customizations. For example, infoboxes are a notable feature of many wikis, but they are implemented separately in each of them, so Visual Editor cannot have an “Insert infobox” button, but only an “  ” button, and each editor has to know the name of the template and type it.
 * Wikis with smaller communities are disadvantaged because they don’t have the expertise to develop templates and gadgets, and there is no way to port them easily. New wikis, in particular, start with a very bare-bones installation of MediaWiki and extensions, whereas a lot of the older and larger sites’ functionality is actually provided by templates and modules, which cannot be quickly installed and have to be imported manually.
 * Incompatibilities between deployed software and local customizations cause bugs that are hard to anticipate and detect. Fixing them must be done on each wiki site separately. This can even lead to the rejection of some features by the community, waste of development resources and friction between the software developers and the editors. All of this could be avoided.
 * The differences between the local customizations make articles harder to translate. Resolving this problem will dramatically increase the speed in which content is translated and made accessible to larger parts of humanity.

Despite being very large, these problems are overlooked most of the time. Software from the different groups is often blended seamlessly into the site’s user interface. People who primarily edit in one language or project may not realize that a certain feature is only available on that project, and think that it’s available everywhere. Even experienced software designers and developers often make this mistake.

提案された解決策:


 * 1) Allow making some templates and modules global, similarly to images on Commons, global personal JS and CSS pages, global user pages, etc. (Gadgets should be global as well, but this is already possible in practice using hacks such as those used by HotCat. It’s not perfect, but it’s much less problematic than the issue with templates. Gadgets are therefore not in the scope of this proposal.)
 * 2) Each editors community will keep its independence to maintain local templates and to make local changes to global templates’ functionality and the information they present to readers.
 * 3) The user interface strings of the global templates must be translatable in a translatewiki-like interface, similarly to extensions.
 * 4) The templates and modules will still be editable as wiki pages and immediately usable in all wikis after publishing.
 * 5) Policies about maintenance, sharing, protection, and deletion of templates and modules will be developed by the editors community.

Building the infrastructure for global templates and modules is challenging, however the core platform developers have said multiple times that it’s possible, and mostly requires product management and dedication. It has to be done, because the lack of global templates is the biggest usability challenge for all stakeholders: developers, new editors, veteran editors, and translators, in all languages and in all wiki projects.
