can i create it for commercial purpose.
Concerning copyrights, see
http://dictionarymid.sourceforge.net/copyright.html.
Let me explain a few words: the DictionaryForMIDs application (the program) is copyrighted by the GPL. Please take care to fully comply with the GPL when you distibute the DictionaryForMIDs application. The GPL allows commercial distribution, but please read the GPL thoroughly to be sure that you fully comply with the GPL.
For example you must clearly state that the software is Open Source and that it is distributed under the GPL. This must be very clear to all recipients of the DictionaryForMIDs application (i.e. so that the recipient realizes that he was stupid when he payed for it

) . Also note that each modified version of the DictionaryForMIDs application must be distributed under the GPL.
For the dictionary that is included in the DictionaryForMIDs application, the copyright may be different. The copyright is specific to each dictionary, you need to check specifically for each dictionary. In any case, please shy away from selling any free dictionary that was set up by a volunteer, that would be a shame.
There are two ways for using DictionaryForMIDs commercially:
- Setting up a commercial dictionary and selling it with DictionaryForMIDs
- A commercial organization that uses the DictionaryForMIDs application with its existing free dictionaries (no dictionaries are sold in that case, nobody earns any money from sale if DictionaryForMIDs)
Just ask further on this topic if I can help there any further. I appreciate any questions on this topic.
Regards,
Gert
