Thanks for the input, I'm still thinking whether an offline or an online
solution would be more sufficient. OGR driver would somewhat be simple even
if it's used to convert the data source to shapefile directly (ogr2ogr).
Scripting requires the user to set up further environments (Python, C# Java
whatever) which is more complicated to utilize in most cases.

Best regards,
