OGC Web Services Auto-discovery using OPML

Posted by Patrice Cappelaere Thu, 01 Mar 2007 16:12:00 GMT

How can a data node make its web services discoverable to an inquiry from an aggregator (like an OGC Catalog)?

One idea might be to use OPML This is nothing more than an outline structure of web services the SWE data node can provide.

The data node can simply add a simple link in the head section of the top page to facilitate auto-discovery:

<link rel=”outline” type=”text/xml+opml” title=”OPML” href=”http://eo1.geobliki.com/geobliki.opml” />

If a user has an OPML reader installed such as this for Firefox, a little icon appears at the bottom of the browser. Click on it to discover the new capabilities.

I would love to get some feedback from the catalog guys :)
