Make Contexture content shareable

[Nagelfar]

Content captured in Contexture should easily be shareable in web based environments.
E.g. provide something like Twitter Cards or OpenGraph meta-tags ensure that content can be embedded & read.

Adding meta-data into head is hard with Elm. Solutions like elm-pages only work for static generated sites.

A possible solution could be to split up the single Elm-SPA into at least the following parts:

• Domain overview
• Domain detail
• Bounded context detail

Then each of these parts could be pre-rendered with meta-tags on the server. Then including a title (domain/bounded context title) and description (domain/bounded context description) on the server is simple, while rendering the remainder of the page client side.
Splitting up the application in these parts should be quite simple.

Alternatively solutions:

• a full fledged serverside rendered process (rendering all of it on demand on the server)
• manipulated head-tag with JavaScript (via Elm-ports), but this relies on the JavaScript execution on embedding the content (which might not be working)

Would JavaScript interop do the trick? create-elm-app example:

elmSpa.ports.urlChange.subscribe(function(title) {
    window.requestAnimationFrame(function() {
        document.title = title;
        document.querySelector(
            'meta[name="description"]'
        ).setAttribute("content", title);
    });
});

I have no idea if this would work with e.g. Twitter cards or other places were content is embedded, as it relies on executing the whole page with JS.
