 /*
 * This script attemps to import a draw.io (aka diagrams.net) diagram into an Archi model by 
 * empirically mapping the observable attributes of the XML elements exported from draw.io to Archimate
 * elements and relationships. Please note that this mapping is fragile, because draw.io doesn't seem 
 * to generate the XML attributes in a very consistent way; also, we must unfortunately use element color
 * as a key differentiator, to compensate for the lack of usable archimate information in the XML file. 
 * All of this means that minor changes in the draw.io XML format can break the mapping...
 * Notes:
 * -- To generate the draw.io file, export it as an *uncompressed* XML file.
 * -- When running the script, make sure you have set the current model to import it in (e.g. by selecting a view in the model)
 * -- In draw.io, make sure that the relationships you want to import are *really* connected to their source and target elements
 *    (in Archi, we need both end-elements to create a relationship)
 * -- The script generates a view containing the newly imported objects, but this is pretty much experimental
 *    (the layout for the elements is the same as in draw.io, but the relations just have the default routing provided by Archi)
 * -- The current code does very little error/exception handling
 * 
 * NB: all of this is pretty much a work in progress. Possible future improvements:
 * -- More test cases!
 * -- Better error/exception handling
 * -- Create new objects in a dedicated folder ?
 * -- ..

	* This script attemps to import a draw.io (aka diagrams.net) diagram into an Archi model by
	* empirically mapping the observable attributes of the XML elements exported from draw.io to Archimate
	* elements and relationships. Please note that this mapping is fragile, because draw.io doesn't seem
	* to generate the XML attributes in a very consistent way; also, we must unfortunately use element color
	* as a key differentiator, to compensate for the lack of usable archimate information in the XML file.
	* All of this means that minor changes in the draw.io XML format can break the mapping...
	* Notes:
	* -- To generate the draw.io file, export it as an uncompressed XML file.
	* -- When running the script, make sure you have set the current model to import it in (e.g. by selecting a view in the model)
	* -- In draw.io, make sure that the relationships you want to import are really connected to their source and target elements
	* (in Archi, we need both end-elements to create a relationship)
	* -- The script generates a view containing the newly imported objects, but this is pretty much experimental
	* (the layout for the elements is the same as in draw.io, but the relations just have the default routing provided by Archi)
	* -- The current code does very little error/exception handling
	*
	* NB: all of this is pretty much a work in progress. Possible future improvements:
	* -- More test cases!
	* -- Better error/exception handling
	* -- Create new objects in a dedicated folder ?
	* -- ..
