What's the alternative? For clients to refresh their copy of the "parent" resource [there may be a better term for this... I mean the resource used to access the resource that is to be gotten] often? For a commonly interactively accessed thing, it would introduce a lot of latency for clients to get it every time, so I suppose it must be cached... and then the cache of the parent resource be refreshed regularly and in case of failure? How far up the tree should that go?
In other words, if I want to get the Twitter feed for Joe's "ABC" group and I don't want to hardcode the URL for that resource, how often should I download (and cache), parse, and traverse the resources for Twitter's users then Joe's feed then Joe's ABC group, etc.? Or am I misunderstanding this?
