IndexGeo Spatial Data Directory - discover geospatial web services

Note: This is a specialised gateway which searches some geospatial data discovery services to discover relevant web mapping services.

Words in full-text or fields	help \| top
Hint: more than one word in "text input" constitutes a phrase Hint: use wildcard symbol "`region`" to match "`region, regions, regional`" Example:* `water` Example: `water quality`

Document repositories	help \| top
Note: select one or more nodes (document repositories) Note: selecting too many nodes may cause slow search

Note: Most production ASDD nodes do not yet have any metadata records that describe services. So only rely on the nodes that are pre-selected below.

Need to decide on the structure and element names in the XML response to the Z39.50 R ElementSet.
See explanation of how it operates
The ISO19115 metadata (and Australian Profile) needs to have more mandatory elements within the onLineSrc element, i.e. when an onLineSrc element is used it must contain linkage and appProfile. The appProfile is currently optional, which means that search and presentation is crippled.
The XSL transformations are attempting to accommodate both old and new style WMS Capabilities XML. This is difficult because there are extreme differences. Seems to be working.
We rely on some implicit syntax within the content of the <appProfile> element, e.g. ogc:WMS-1.1.0-http-get-capabilities This is dangerous. It would be better to have some explicit extra elements in the ISO19115 XML fragment, or make better use of the <function> element, i.e. add ISO codelist entries for GetCapabilities and GetMap.
Ensure that our GetCapabilities and GetMap request are compliant with the WMS Spec and also Guide to Making Your Data Products WMS-Compliant. We think that we are OK, but it is confusing as to what are required parameters in the URL.
Need to fold our code changes into the official Isite distribution. The revised Isearch doctype for "anzmeta" is provided.
Need more Australian nodes with descriptions of mapping services (e.g. WALIS, AUSLIG, AGSO, BRS, other industry)
For general gateway notes see the main Test Gateway

Conduct a normal search (the single word water will suffice, and completely empty search terms is OK too)
Behind-the-scenes the gateway will add an extra search parameter to ensure that only metadata records that contain links to WMS services are returned.
