I had a request today to produce all items in my GN repository
referenced in a sitemap.xml file [1].
I think it would be valuable to be able to (optinoally) expose GN
repository resources with the sitemap.xml format. Something like:
(http://devgeo.cciw.ca/geonetwork/srv/en/portal.sitemap?format=xml)
...where format can control XML (FGDC/ISO/DC/etc.) or HTML output.
...can return a sitemap document which folks can submit to search engine
crawlers.
Comments?

We must expose them to the crawlers. Good idea Tom. How hard to
implement is this?

I implemented this in Python. Basic steps:
- query database with "select id, schemaId, changeDate from Metadata where isTemplate = 'n'"
Return XML like:
<urlset
xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
xmlns:geo="http://www.google.com/geo/schemas/sitemap/1.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9 http://www.sitemaps.org/schemas/sitemap/0.
9/sitemap.xsd">
<url>
<loc>http://host/geonetwork/srv/en/fgdc.xml?id=194</loc>
<lastmod>2009-04-09T15:15:04</lastmod>
<changefreq>monthly</changefreq>
<geo:geo>
<geo:format>fgdc-std</geo:format>
</geo:geo>
</url>
...
</urlset>
The value in /urlset/url/loc would be either XML (the process would have to figure out the schemaId, and then create the URL appropriately), or HTML (e.g. http://host/geonetwork/srv/en/metadata.show?id=194).
