Geodata Discovery

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:

1. 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)
2. Geotag icon (Microformat) for human readability and trustworthiness (Google's principle of visual control).
3. A leightweight haversting interface like OpenSearch-Geo
4. Extension of GetCapabilities from OGC WxS specifications
