[Geodata] Fw: Re: [GeoNetwork-devel] SMET (Spatial Metadata Extraction Tool)

[jo at frot.org]

This sounds like a useful project - a python based metadata extractor
that is moving from an ESRI backend to an OGR one and will be GPL.
It sounds like a more robust version of toys i have worked on in the past.

Hi Jeroen,

SMET is a tool I first started developing last Summer.  It started a simple
interactive gui tool to extract the bounding box in lat long from a
geodataset that I could cut and past into a GeoNetwork metadata record.  It
has since grown to include other extractable geographic metadata elements
such as projection information and pixel size (for images).  I also use it
to extract UNC paths to provide a data location and create and modify dates. 
The idea was to provide a tool that would automatically extract whatever
metadata it could from a geodataset and thereby speedup the capture of and
increase the accuracy of our metadata records.

This tool was built in python using ESRI GeoProcessing tools.  I am now in
the process of replacing the ESRI calls with gdal/ogr.   I have secured some
outside contracting to help me clean up and restructure my code and to
migrate to the gdal/ogr tools.  This contract explicitly states that the
resulting code will be gpl.  This contract concludes at the end of June by
which time the code should be cleaned up enough to be useful to others ;-). 
I have not yet determined where or how to post it.

Currently, SMET spits out the metadata to a screen from which I copy and
paste into a metadata record.  The next development step will be to spit
this out into xml .  This will then be used to (somehow yet to be
determined) update existing or create new metadata records in GeoNetwork. 
Further in the future I have thought that SMET would be able to be run as a
service/daemon and become something like the crawler tool that Francois
proposed last year.

The main concern that led to the creation of SMET was to simplify and
decrease errors in metadata collection.  I also hope that it can help ease
maintenance and update task.  It could also be developed to scan directories
for data discovery.  The biggest unknown I have right now is what is the
best way to integrate this with GeoNetwork?

Cheers,
Byron
