I'm planning on getting rid of redirect attributes to handle the Who, About
and Date attributes in the Summary Table. Instead I plan to add an explicit
Who, About and Date attribute. By noticing when attributes that affect the
value of Who, About or Date change (using onValueChanged), I'll update Who,
About and Date as necessary.
This is simple to implement and eliminates the current problem where Who,
About and Date sometimes doesn't display the correct value. It also doesn't
require a special "computed attribute" that isn't stored in the repository,
so you can always search for Who, About and Date like any other attribute.
Finally, it allows Andi to get rid of redirect, which simplifies the
repository design.
We recently discussed something related to this on IRC and came up with a new
attribute aspect, bequeathTo, that would allow you not to have to use
onValueChanged() to bequeath a value from an attribute to another attribute
after it changed.
I'm planning on implementing this in the next few weeks.
