Global templates

Many of the most notable features of Wikimedia sites are implemented as templates and Lua modules: Wikipedia Infoboxes and citations, maps, navigation headers on Wikisource and Wikibooks, conjugation tables in Wiktionary, deletion and merging procedures in multiple wikis, and hundreds of others.

Even though many of these features are very prominent, there is a significant hurdle to their development: On Wikimedia projects they are stored separately on each wiki. While it allows the local editors community on each wiki a lot of freedom to innovate and develop the templates that it needs, it makes it very inconvenient to share templates that could be shared across wikis, and to translate them.

Over the years there have been several proposals to make templates shared across wikis. Editors have requested this since 2004. On the technical side, there were Scary Transcluding, Shadow namespaces, and Multilingual Templates and Modules. It was also included, without a specific timeline, as one of the goals of Platform Evolution project. On the community side, the topic came up multiple times in the Community Wishlist Surveys, and received a lot of votes. Despite many discussions, these proposals were never fully implemented.

The problem remains, however, and needs to be resolved, but such a project requires wide organizational and community commitment. This page is an attempt to build such commitment.

'''This is not a project that is being executed or planned to be executed by anyone at any defined point in time, at least not yet. This is just an idea, albeit a very detailed one.'''

In the wiki spirit of "no ownership", these pages belong to the community. Feel free to comment, edit, improve, discuss, express objections, etc. The more it is owned by the community, the better it will all be.
