There's a reasonable need to get a shared, standard set of templates, modules, js scripts for wikisource projects - all projects sharing a common, identical goal and facing with the same, identical issues, and needing the same set of international, standard metadata. Nevertheless it's very difficult to synchronize efforts, while working into different "boiling" projects; and I personally found very frustrating to admit that some painful efforts to solve specific issues turned out to be simply a "rediscovering the wheel". :-(

Oldwikisource, given its "neutral" character, could be IMHO the perfect project to share the best of source projects, and there's a perfect kind of works that could uploaded into oldwikisource and proofreaded using common, shared styles & tools: they are multilanguage works.

Presently, we are going to upload and proofread a three-language (French, German, Italian and some English too) magazine: Histoire des Alpes - Storia delle Alpi - Geschichte der Alpen. It's released under CC-BY-SA-2.0 licence, My idea is, to upload it into oldwikisource, transcluding it by Iwpage into any interested projecy - the proofreading/formatting job being done into oldwikisource, with common tools, common templates, common modules, common "styles". What do you think about?
