More WxS Hinting From Feeds

Looking back, I realize I forgot to mention an easy way to help ordinary web clients find and tap into WMS from a feed: HTML forms. Here's a feed entry representing a form:

  <title>GetMap Form</title>
  <summary>Easy entry point to a web map service</summary>

where getmap-form.html is:

  <form method="GET" action="">
    <input type="hidden" name="service" value="WMS"/>
    <input type="hidden" name="request" value="GetMap"/>
    <input type="text" name="layers" value="layer1,layer2"/>
    <input type="text" name="bbox" value="-180.0,-90.0,180.0,90.0"/>

For a more concrete (though not exactly WMS) example, see this form.

Hi Sean, Thanks for some great input! I removed my URI Template stuff from the feed again and now included a full GetMap request producing a PNG file and added a link with only the basic information and a (custom) hint. That should work for people that want to consume the feed information and exploit the W*S services. The above is also a great idea, although it is tied to a specific client and that's something I hope not to do to make it easy for other clients to use the resources in a clean way. I may still include it though :-) Ciao, Jeroen

Tied to a specific client? Not really: there's a very wide range and huge number of web clients that handle HTML forms. There's nothing out there that handles the hints in your links. Specifically, I did a GET on one of your alternate links and it gave me a service exception document (along with a completely misleading HTTP "200 OK" status). Web clients expect dereferenceable, not bogus, URIs in a link.
