Multiple links (for a collection) on a atom entry

[Julio Lima]

Hi,

I'm working on a atom-entry spec for a "destination" feed. This
destination has relation with "credit-card" (all credit cards usually
accepted on that destination). Of course, one destination may have
more than one credit card associated.
So I thought on two different approaches :

First one, listing all links direct on entry (destination.xml) and
another way is to link to a entry point that list all credit cards
accepted by a destination (destination2.xml) :

Which one would you use? Any pros & cons ?

Thanks a lot!

Julio,

I am afraid you need to provide more context....I don't get what you want to do.

My scenario is : A already have one server, this server is responsible for
one research (credit card), and I can access it using a AtomPub protocol.
Now I am developing a second application, one a second server, which need to
provide information about about generic tourists destinations. For each
destination I would like to link all acceptable credit cards.
To expose this "destination" resource, I would like to use AtomPub as well.
And to "link" both resources, I thought that atom:link element is the more
appropriate tag, right?

So, I end up with two different possible atom feeds for a destination (see
below).

The difference between them are minus, but important.
The first one has only one link, to all credit cards accepted by a given
destination (possible a complete feed).
The second one has 3 links, one for each credit cards accepted by a given
destination (possible 3 entries).

My question is : both approaches are correct? Which one would you use? Any
pros & cons ?

Thanks a lot!

Yes.

So, I end up with two different possible atom feeds for a destination (see below).

The first one looks better. (the type is wrong though, you need to say ..+xml;profile=""

The difference between them are minus, but important.
The first one has only one link, to all credit cards accepted by a given destination (possible a complete feed).
The second one has 3 links, one for each credit cards accepted by a given destination (possible 3 entries).
My question is : both approaches are correct? Which one would you use? Any pros & cons ?

I would probably not prepresent a credit card with an atom entry, only when it appears inside a feed (example one).
