Capability: Support hyperlinks from markers or vector features

[Malvoz]

This issue is for discussion of the map viewer capability “Support hyperlinks from markers or vector features”.

[Malvoz]

Because markers and vectors can overlap, it is important to consider the problems that may cause about interacting with these links, especially for users with a pointing/touch-enabled device. See: Maps4HTML/MapML-Proposal#41.

One can now link a map-properties value to a remote location, in this way one can link from a feature to remote source

<map-properties>
        <table>
          <thead>
            <tr>
              <th role="columnheader" scope="col">Property name</th>
              <th role="columnheader" scope="col">Property value</th>
            </tr>
          </thead>
          <tbody>
            <tr>
              <th scope="row">Name</th>
              <td itemprop="amenity"><a href="https://en.wikipedia.org/wiki/Ottawa">Ottawa</a></td>
            </tr>
        </table>
<map-properties>

Reverse link could be more challenging?

https://example.com/index.html#mapml=example&feature=Ottowa

By 'reverse link', can we clarify, is "https://example.com/index.html" a page that has a/some map(s) on it, and what behaviour are you expecting from the mapml #fragment?

That's how I interpret it as well.

what behaviour are you expecting from the mapml #fragment?

We did discuss such behavior briefly in Maps4HTML/MapML.js#378, IMO:

This is essentially Text Fragments, but for maps

I think the appropriate capability to hold the discussion is #146, because the supported use case #41 mentions:

• bookmark a view/location so you can come back to it the next time you visit the webpage

correct, the self link (permalink) would have a reference to a map instance on a page, (probably a layer reference) and an object reference

expected behaviour for example that the map is centered on the feature, maybe a balloon is opened with details on the feature

but these are just wild ideas, probably hard to implement
