[oslc-core] ChangeLog Proposal Finalization

Hi Frank,
I didn't mean to suggest that it's simpler with the single-list approach to
determine how/when to get the subsequent pages. But rather, once you have
the data, it's easier to work with, particularly if you're interested in
data that crosses page boundaries. You can just merge the models (Model.add
() in Jena) and you're left with a nice, simple list to traverse, rather
than a nested structure defined by custom vocabulary.
We've been doing client work where we actually use Jena as the underlying
model, so the simpler option seems more attractive from that perspective.
Cheers,
Dave

Hi Dave,
That's an interesting suggestion - just use addressable entries at the page
boundaries to link to the continuation of the list on the next page.
Personally, I think I still prefer the design where pages (or segments) of
the change log are explicitly modeled. I think it is very simple to
understand, and the ChangeLog segments could themselves be interesting
stand alone URLs (e.g. the changeLog/segment for a specific date).
I'm not sure the single list design is simpler anyway. The client will need
to check each node to see if it's a blank node of if it requires an HTTP
get. The list-of-list model requires only one check for next segment, when
it gets to the end of a page's list.
Thanks,
Frank.

Hi Frank et al.,
Apologies for not being able to make it to the meeting today, and if this
input is too late to be useful, I certainly understand that.
I think there's still an existing issue with the latest pagination
proposal. It looks to me like a list of lists or, rather,
something-like-a-list (using custom vocabulary) of lists (using standard
vocabulary). And I think that's more effort for a client to understand and
deal with than a single, basic list would have been.
If the key concern is the use of resources with URIs (as opposed to blank
nodes) within each "page" resource, you could still use a single list with
mostly blank nodes, but retrievable resources for the first entry on each
page.
Cheers,
Dave
