Why Command Helpers Suck is an amusing rant by Kristina Chodorow (author of MongdoDB: The Definitive Guide) on the different command helpers for the same underlying database commands.
Shades of XWindows documentation and the origins of topic maps. Same commands, different terminology.
If as Robert Cerny has suggested topic maps don’t offer something new then I think it is fair to observe that the problems topic maps work to solve aren’t new either. 😉
A bit more seriously, topic maps could offer Kristina a partial solution.
Imagine a utility for command helpers that is actively maintained and that has a mapping between all the known command helpers and a given database command.
Just enter the command you know and the appropriate command is sent to the database.
That is the sort of helper application that could easily find a niche.
The master mapping could be maintained with full identifications, notes, etc. but there needs to be a compiled version for speed of response.
