[TYPO3-english] what is good use case for adv. page-content handling?

[Santiago]

Hello,

My requirements are:
I have pages with various content-parts, where the content-part have access 
start- and stop-dates (which should be visible in the webpage), but the page 
should show only a teaser for that content. The content title should be a link 
to a page (not accessible from normal navigation), that shows the whole 
content.

My questions:
1 how can I access the date-fields

2 how can I best workout that preview? I would like the editor having to 
create only one content, which should be processed by 2 pages differently (is 
it possible for a content be part of multiple pages?)

3 when a content has a start- and stop-date ... is it possible to process/show 
that content from a different page (i.e. archive page) outside the timeslot - 
so the evaluation of access-times depends on the page.

4. is it possible to realize a kind of automated linking - means, that the 
page with the previews shows active content (respect to timeslot) only?

5. if point 4 is possible, how can I bring a default content into play in case 
that none of the related contents is active?

Links or book titles related to the problem(s) are welcome.

kind regards

Santiago
