[mapguide-users] How to programmatically migrate Unmanaged SHP to Managed SHP?

[everling]

I have several hundred SHP files that needs to be migrated from their current
Unmanaged state to a Managed state, and in the process programmatically
alter the LayerDefinitions to point to their new locations. Unless I am
mistaken, neither MapGuide Studio nor Maestro can do this, so I have been
researching the MapGuide API.

The MgResourceService and the MgByteSource class does provide most of the
interfaces needed to do the job. I am able to retrieve a list of aliased SHP
file paths to be migrated and I am able to store SHP files into a managed
SHP FeatureSource. However, unless I am again mistaken, the MgByteSource is
unable to process the aliased paths like '[Alias1]/example.shp'. It works
fine if I give it an absolute path like 'C:\SHP\example.shp' but it doesn't
with an aliased path.

Assuming that this was intended, is there an officially blessed method to
properly resolve the paths? I have been unable to find any API method that
will do it. There was however a tantalising hint of it in the MapGuide RFC 2
( http://trac.osgeo.org/mapguide/wiki/MapGuideRfc2 ) under
"MgResourceService::EnumerateUnmanagedDataMappings()", but this method is
neither present in the current API documentation and attempting to call it
regardless will throw an undefined method exception.

A workaround this problem is by reading the necessary mappings by examining
the serverconfig.ini file, but there doesn't seem to be any method to
guarantee that I am looking at the correct serverconfig.ini file (unless the
correct path is hard coded in), especially on servers with multiple versions
of MapGuide/MapServer. Or is going by the webconfig.ini sufficient
guarantee?

Or maybe there is an alternative method of handling this that I am not aware
of? As far as I can tell, the MgResourceService::GetResourceData is only
intended for Managed feature sources, leaving me stuck with the
MgByteSource.

Thank you all for your time.
