It really did serve as a kind of local filesystem for pipelines. 14:15:27 ...In particular, this turned out to be useful in steps that produce unordered sequences of documents. 14:15:55 ...A resource manager might figure into the design for how steps that produce or consume unordered sequences coordinate on how the decide what's available. 14:16:13 ...At the extreme, a RM gives us a very different processing model where steps are thought of as producing and consuming named resources. 14:16:22 ...And other steps can use those resources without plumbing directly between steps. 14:16:48 ...A simple way to put that is: what is the impact of having a resource manager on step dependency calculations. 14:17:06 ACTION: Henry to review Markup Pipeline documentation and report anything useful he finds 14:17:28 Alex: Is the XSLT import/include case relevant here? 14:17:32 Norm: Yes, I think that's exactly the same use case. 14:20:49 Some discussion of caching and resource managers and related issues 14:22:50 Henry: Have we reached agreement about whether we want to adopt the XSLT/XQuery invariant 14:23:27 ...roughly speaking this says that any given XSLT or XQuery episode does gets on URIs exactly once and you always get the same document. 14:23:35 Norm: Yes, that's correct. 14:24:02 Norm: But in XProc we didn't want to make that requirement 14:26:54 Cornelia has joined #xproc 14:31:08 Some discussion of security 14:31:52 Henry: This is related to the RM and the ability to attach "out of band" information to documents. 14:32:08 ...We've talked about some possible others, like serialization parameters 14:35:55 Topic: Any other business 14:36:07 Murray: Are we planning a f2f meeting? 14:36:17 Norm: Yes, at TPAC in Lyon, FR in November, I believe. 14:36:22 Adjourned 14:36:28 -Murray 14:36:30 - +1.805.560.aaaa 14:36:35 -Alex_Milows 14:36:36 -Norm 14:36:37 -ht 14:36:38 XML_PMWG()10:00AM has ended 14:36:38 Attendees were Norm, ht, Alex_Milows, Murray, +1.805.560.aaaa 14:36:50 rrsagent, draft minutes 14:36:50 I have made the request to generate http://www.w3.org/2012/05/31-xproc-minutes.html Norm 16:03:56 Zakim has left #xproc
