Notes about auto-discovery of geodata by Stefan Keller:

Based on the source indicated below I strongly propose following in order to ease auto-discovery of geodata:

A "see and see also" file containing typified weblinks that provide semantics to help focussed crawlers.
1. Weblink typing: xlink Atom link relation type,
2. Carrier file formats: HTML (Meta Tags) sitemaps.xml , KML, GeoRSS (xlinks)
Geotag icon (Microformat) for human readability and trustworthiness.
A leightweight haversting interface like OpenSearch-Geo
Extension of GetCapabilities from OGC WxS specifications
