From your description I'm not quite sure where in the stack Irmin belongs? Is this to be used by web application developers? I assume note, as this looks like it is targeting more OS level development work? Pretty cool stuff. I am also working on a distributed database, https://github.com/amark/gun https://github.com/amark/gun , that operates at the high level (web/javascript) rather than the low level. Although it looks like Irmin can be used in the browser? https://github.com/talex5/irmin-js https://github.com/talex5/irmin-js ? Would love to hear some clarification.

[ To avoid any confusion, the submitter is not the author of the post :) ] I don't really understand the question about the stack. Where it belongs should only limited by its features. It certainly can be used by people developing browser-based apps. For example, Cuekeeper [1] is a version-controlled TODO manager which uses Irmin. It's also been used with Xenstore [2], which is a different use-case (there are other examples in the readme of the Irmin repo).

As for the rest of MirageOS, Irmin is a "library" database, means that you have a bunch of components than you can re-use in different contexts. Two interesting contexts are: - the browser, where some components of Irmin are transpiled to JavaScript using js_of_ocaml (http://ocsigen.org/js_of_ocaml/ http://ocsigen.org/js_of_ocaml/). Cuekeeper (http://roscidus.com/blog/blog/2015/04/28/cuekeeper-gitting-things-done-in-the-browser/ http://roscidus.com/blog/blog/2015/04/28/cuekeeper-gitting-t...) is an interesting use-case for that. - the kernel, where some components of Irmin can be compiled into a unikernel and be run on top of Xen/baremetal, bypassing the OS completely. Irmin-ARP (http://somerandomidiot.com/blog/2015/04/24/what-a-distributed-version-controlled-ARP-cache-gets-you/ http://somerandomidiot.com/blog/2015/04/24/what-a-distribute...) is an interesting step is the direction of exposing kernel data and do interesting stuff with it.

Like most OCaml libraries, Irmin can be used in the browser by compiling your program with js_of_ocaml. My `irmin-js` experiment provides a Javascript API to Irmin, so you can write your application in Javascript too, rather than OCaml. My JS isn't very good though; here's what my example code ended up looking like: https://github.com/talex5/irmin-js/blob/master/examples/tests.js https://github.com/talex5/irmin-js/blob/master/examples/test...
