which would make a lot of sense since they represent some really key
information for querying.
So seb please add them.

Ok, done.
I just added two timestamp descriptions to PRStructure (creation & modification).
Creation is initialized with "Timestamp now" in #doExecute of PRAddCommand.
Modification is initialized/modified in #doExecute of PREditCommand.
They can be retrieved by their respectives selectors and by #creationTimestamp and #modificationTimestamp if no persistency scheme is plugged.
It seems to work (and it looks nice in the report ^^). Did I forget something?
Anyway Lukas, we were talking with stef about adding "comparison description" to the meta-descriptions of Magritte.
For example:
I have a report that lists every pages of Pier. It's a MAReport, so it uses pages descriptions and it's very nice.
Now, I want that report to show me only pages that match a specific query (say Creation timeStamp = Today). Something in the Macintosh finder's style ;). It could be great, to build this query, if I could choose a description in a dropdown menu and then, this description tells me "you can compare me this way, using these methods". Then I show another dropdown menu with these methods. And so everything could be done dynamically. If you decide to add a new description to PRStructure, then my report will still work, and so on...
Do you see what I mean and do you have an ideas on that? :p
