[Zope] better than Notes (but where are the views ?)

[chas]

hi folks, 

i was out of the fold for about 4 months and just returned to zope... 
i'm blown away by the progress it's making. serious kudos to digicool 
and the entire community 8)

anyway, i've just been playing with zclasses and have to say
they're the damn nearest thing i've seen to Lotus Notes' Designer -
hell, they're even better : true object orientation and we can use 
python. (anyone who's had to use lotuscript/vb knows what i mean). 

however, i'm missing sommething. i can create these documents (oops,
i mean zclass instances)  but  how do i get them out of the object db
again ? is it possible to create the equivalent of Notes 'views' ?
ie. filter all the instances of a class and/or with certain values 
of given properties ? 

eg. just say i had a zclass called "articles" and each article has
an "author" and a "date". i then create 100 instances of this zclass.
how could i display all the articles written by a given author or
on a certain date ?

cheers
