Dear Elie, Thank you for the kind response to this idea.
In my discussions with one of the contributors to the project described below I have learned that MEI itself is presently being developed in order to capture all of the needed information and attributes that the manuscripts present. This is a work in progress. I saw a draft of a table of St. Gall neumes that the group is working on and sent the NABC table to them for comparison. I think that it is possible that Gregorio has already worked out some of the encoding problems, although, as you say, there are still problems to solve. Nonetheless, if there were to be a way for porting information between the two systems, it seems like discussions between the platforms as they develop now would help ensure the greatest success of the aim. Perhaps there are insights that this group could offer that would help improve NABC also. Thank you for your openness to this idea, and to your willingness to help in some way in developing a script for porting data to MEI. I will continue conversations with those involved in the Cantus Ultimus / SIMSSA <https://cantus.simssa.ca/> project and be in touch about potential collaborations with Gregorio.

Well, the main difference I see is that MEI is far less precise than Gregorio for square notation. For instance MEI doesn't seem to allow episemi, aucta, etc. and doesn't differenciate the many different ways to write a pressus... Unless there is more than of MEI that I didn't see? Also for nabc, I'm no expert but the situation seems to be exactly the same, if you take a look at https://github.com/gregorio-project/gregorio/releases/download/v4.2.0-rc3/GregorioNabcRef.pdf you'll certainly see many neumes that you would all encode in the same way in MEI. > My question: I wonder if it might be possible to find a way to allow > GABC / NABC to communicate and share data with MEI? I think it would be fairly easy to allow Gregorio to write MEI, but it would be read-only: as there is more information in gabc or nabc than in MEI, it seems that it would not make much sense to turn MEI into gabc/nabc... I'm not really sure about the best way to do that though. My first idea would be a python script, but it would have to make an interpretation of gabc which may be slightly different from Gregorio in corner cases... or it could parse the "dump" output of gregorio... It would have to interpret nabc anyway, as the interpretation in done on the Lua side.

I'm not able to invest much time into this project, but I can give a few directions and hints. But it's possible that a script for converting gabc/nabc into MEI is not that hard and could be make quickly at least in a first version... Thank you, -- Elie
