Hi all: I'm sitting on a pile of imagery that doesn't have much in the way of metadata. I'm trying to develop a strategy to get minimal records for the imagery into GeoNetwork. One idea would be to create a minimal metadata record as XML file for each image or series of images by harvesting what I can using GDAL via a script. Then bulk loading via the GeoNetwork admin tools. I'd have folks complete the records later (if possible).
Does this sound like a reasonable approach?
If so, where could one get hold of a metadata XML template file?
Thanks for any advice!
Steve
Not sure that will help you,
But we are thinking about to do the same thing for all the map and soil
picture we have
And coming from postgis, shapefile and other resource we have to describe.
In any case your feedback interest me very much

Hi Steve,
Using the metadata editor you take an existing template and remove all fields you don't want to fill (and possibly add those you do want on top of the default ones in the template). After saving you can switch to XML view and use the generated XML as your template. Consider using the ISO19139 based templates (the default sample records on Africa and East Asia are based on that encoding).
Make sure you leave the FileID empty (remove the UUID) so that on import new unique UUIDs will be generated for the metadata entries.
I've attached the plain raster template (ISO19139 encoding) that GeoNetwork uses. You can also edit that one manually, even if that can be a bit cumbersome.
Taking it a step further, giving you more control on import, you could consider generating MEF files. These are zip files with a defined content. It allows you to include thumbnails generated by GDAL for instance and get those inserted when importing the whole collection. A description of what files sit inside the MEF file can be found in the manuals (Chapter 8 in the server reference. instructions on how to import & export mef files is in the admin-guide.pdf). Sample mef files can be found in ../gast/setup/sample-data directory.
Ciao,
Jeroen
