I started a NodeFactory for GDTF files, I managed to follow the examples which were closer to this subject (by using files both implemented by @sebescudie ). A common thing in both approaches is one or more txt files which keep track of the entries in the folder. My question is if it would be possible to avoid this, and just populate a folder with xml definitions which will be used per project.
This is where I am atm, the NodeFactory seems to register properly but I do not have access to the gdtf files I am putting in the subDir
