Hi Romain,

The locators TF is fairly new, so there is not much recorded yet. There is a wiki at [1] and much email on this list. We put together use cases about packaging quite a while ago [2].

Romain – I am not convinced that locators are dependent on the format, packaging or online/offline state.  It could well be that locators are (and perhaps should be) agnostic, just as the web itself is.   The only thing that is “specific” about a URI is the protocol itself – but beyond that, it doesn’t matter what is on the other end or how you get to it.

Oh, I 100% agree. I was talking about the Locators Task Force's **work**.

It's clear from this thread that the Locators TF's work is strongly dependent on several other aspects of PWP, in particular on packaging and offline/online approaches, and consequently on the PWP manifest, which is likely to be a key part of solving these issues.

I now see that Dave just started a thread on the manifest. Great!
Are there wiki pages or other info that would summarises the current views and decisions on the offline/online mode and packaging stories? or is everything described in the PWP editors draft?.

Sorry if I missed some bits. I'm a recent member of the IG, although I've been watching from the peanut gallery for quite some time :)

I think the goal should be somewhere in the middle. I agree that the definition of PWP should be, as much as possible, implementation agnostic, but I agree with Dave that saying "we don't care" is also not appropriate.

We may have to define a PWP Processor in the abstract sense. What a processor is supposed to do to answer to different use cases, what are its functionalities, that sort of things. We may not define it in a normative way in the sense of some formal language or terminology, but we have to understand what can, cannot, should, or should not be done with a PWP. And it is certainly important to know whether the realization of such a PWP processor is possible with today's technologies, what is PWP specific and what can be reused off the shelf, etc.

Nick – the specifics of how an RS chooses (or not) to cache are out of scope for PWP.  They may make sense for some sort of format-specific work (eg. best practices for PWP with EPUB) but we don’t care about it here.

Remember – PWP is format/packaging and implementation agnostic.   (we seemed to all agree to that pre-holidays)

The fact that an existing web technology can solve a critical use case for PWP is on-topic in my opinion, and learning about such things can only help our work. Such technologies may not be a part of the documents we produce, but saying "we don't care about it here" I think sends the wrong message.
