After Carlsen TMER: Splitting the PGN File, I added the individual PGN file names to Magnus Carlsen's Tournament, Match, and Exhibition Record (2000-). Everything matched nicely and I didn't discover any real problems with the data, although there are a few minor inconsistencies to correct. As planned in TMERs : One Step at a Time, two steps remain:-
- Adding venue to the TMER.
- Removing the external references from the TMER.
I should be able to finish those steps the next time I work on the file. Just one hurdle: Finding time during the year end holiday season!
