[ZDP] Re: Ordering objects and ZDP Tools (again)

[Alexandre Ratti]

Hello,


I feel also that ordering is local issue. The ordering property is likely 
to be used only at a local level to sort among objects with the same type.

If and when we list several object types on the same page (eg. to create a 
book of resources, i.e. what I called a meta-book last week) we're likely 
to first sort the objects by type. Example:

- First sort by global Topic/Subject/Whatever you call it
- Then sort by object type.
- Then sort on the order property.

What I mean is that it makes more sense to display 1st draft, then howtos, 
then FAQs, then Snippets on a specific issue. First general information, 
then specifics.

If we create this kind of global resource listing we may need to find a way 
to order objects types, eg. to make sure that specific types are listed 
before others.
This also apply to a catalog seach: we could always display matching 
resources with a specific object type ordering (1st drafts if any, then 
howtos if any, etc.).


Cheers.

Alexandre
