Ok, I admit the title caught my attention.
Covers the use of merge_data.r for quick and dirty merges of a data set that has diverged.
Good to know if you don’t have a situation where the full overhead of a topic map solution is required.
Do note that the article passes over the question of subject identity or the correctness of the merge without even a pause.
That works, but can also mean that when you have forgotten why the data is arranged as it is, well…, that’s life without subject identity.
