Bernd, Dmitry, and I met with Gabriel and Marko from the services team. Notes:

* Bernd to use https://github.com/wikimedia/service-template-node as a starting point
* Gabriel, Marko to look into cache invalidation / freshness stuff. Usually, for the mobile apps the latest non-stale response is what's wanted by the client.
* Apps team should engage with services on getting the mapping and other fronting service requirements for rest.wikimedia.org deployed.
* The first target service is for something akin to what would be required by a "Wikipedia Lite" experience, similar in terms of data transformation to OCG, Kiwix, Text Extracts.
