But while the draft states that [t]hese [feed] types are complementary (section 1), but is unfortunately silent on how precisely the three different types can be used together. Here are a few questions I still have: - Is it possible that an Archived Feed Document is marked as complete? How is this to be interpreted? Does each Archive Document represent a snapshot of a previous version of the Complete Feed? (This is the interpretation I lean toward.) - Is it possible that a Paged Feed's pages (i.e., its feed documents) are marked as complete? What does this mean? That the Logical Feed in its entirety, of which each page only contains some entries, is considered to be complete? (I would answer this question with 'yes', but note the resulting difference in semantic between complete Archive Documents and complete pages.) - Is it possible to serve a single, possibly large Archive Document as multiple pages? If so, do there have to be next links to the prev-archive document, too, or do paging links only cover the current document. (I would prefer the latter interpretation, as illustrated below.) Archive Document 1 \ Archive Document 2 = \ = Page 1.1 -next- Page 1.2 \-prev-archive- Page 1.1 -next- Page 1.2 Unfortunately I wasn't able to find the answers to these question in the draft itself; it is silent on the interactions between the three feed types. (In particular, it does not even disallow combining them within a single feed!) So, an explanatory section on the various interactions that might occur is probably a good thing to add.

2006/10/9, Andreas Sewe: But while the draft states that [t]hese [feed] types are complementary (section 1), but is unfortunately silent on how precisely the three different types can be used together. Here are a few questions I still have: - Is it possible that an Archived Feed Document is marked as complete? By definition, an Archived Feed is a set of Feed Documents, and an Archive Document is a Feed Document within that set. It cannot be complete, unless it is the only one in the set, and therefore represents the whole Archived Feed as a single Feed Document. It's current link should then point to itself (i.e. the same as the self link). - Is it possible that a Paged Feed's pages (i.e., its feed documents) are marked as complete? No. By definition, a Complete Feed is a single Feed Document. See: 2. Complete Feeds A complete feed is a feed document that contains all of the entries of a logical feed; any entry not actually in the feed document SHOULD NOT be considered to be part of that feed. - Is it possible to serve a single, possibly large Archive Document as multiple pages? Not sure what you're talking about… Do you mean a Logical Feed would be split into stable subsets, each such subset split into unstable Feed Documents? In this case, as each document is not stable, it's a Paged Feed, not an Archived Feed, even if the subset of entries from within 2 Feed Documents form a stable subset. If every Feed Document is stable, then you have an Archived Feed an dyou can link Feed Documents to each others using next-archive and prev-archive. -- Thomas Broyer
