A Long Time Ago…

I just came across this pearl of insight that I wrote a long time ago. I think it still stands:

The problem of understanding historical data and its meaning is both one of determining the user’s understanding and acceptance of the data and determining the flexibility of the supporting software. If a record, as understood by the user community, represents a particular concept in a particular way, the desire to re-use the structure implies that a change in the user culture will be required. If the system itself has built-in constraints as well supporting the accepted meaning, then the problem is in the system’s ability to accomodate new meaning, not just in the user’s willingness to accept new meaning. Where both aspects to the historical data problem exist, it should be easier in the long run not to change the meaning of a structure, but rather to implement a new structure with the desired meaning.
