Implementing Easier and More Efficient Metadata Tags on Wikisource

Disclosure: I am contracted by Creative Commons LRMI Project.

I would like to propose adopting the use of a by-default-disabled Mediawiki metadata feature that would greatly improve the organization and search engine visibility of the content of Wikisource. These metadata tags are part of Schema.org which was developed by Google, Bing, Yahoo, and Yandex, and can be viewed here. The benefit of these tags is that when used within educational content such as on Wikisource, the information contained on the page is made into a way that is easily intelligible to machines by changing just one line with the Mediawiki configuration. An example of MediaWiki using Schema can be seen by using Google's testing tool. These metatags were originally developed by LRMI but their recent adoption of Schema.org is a huge milestone that has great potential to improve the efficiency of the way we are able to search educational resources and content on places like Wikisource.

I have let a light response with the post, however, there are many with more knowledge of this than I, and as mentioned a interlanguage WS community response seems better.
