Those of you familiar with the Movable Type
publishing system will also know the term "permalink". A permalink is a permanent link to a content object as stored in the MT system.
The gravity of this concept alone is worth considering, but is not the point of this entry. I just ran across a great article on future proofing your permalinks. The angle here is that perhaps MT's permalinks aren't all that permanent.
MT geeks will enjoy this step-by-step how to article on future proofing permalinks
. Non-MT geeks might find it interesting to sit back and consider implications and power of permanently addressable content objects.
