[15:10] <cwilper> Meeting now: https://wiki.duraspace.org/display/FCREPO/2010-09-28+-+Special+Topic+-+Moving+Forward+on+High+Level+Storage
[15:11] <cwilper> Aaron giving an update on HLStorage status
[15:11] <cwilper> "Time to kick of concrete design activities"
[15:11] <cwilper> "Next few months = heavily design/theory oriented"
[15:12] <cwilper> Dan: "forward-looking roadmap but breaking into pieces"
[15:13] <cwilper> Aaron: "Scoping for Fedora 4.0, can be less conservative about changes"
[15:15] <cwilper> Aaron: "3 major threads of discussion moving forward: 1) Fedora Object model itself (what changes need to be made in order to facilitate this? DS Versioning?"
[15:17] * mdiggory (~mdiggory@ip72-199-217-116.sd.sd.cox.net) has joined #duraspace
[15:17] <cwilper> "2) API itself. Have initial proposals. First from Aaron was simple, Asger introduced idea of separating into R/W interfaces. Have discussed return values (ticket id for reflecting on status on async storage)."
[15:17] <cwilper> "3) Architecture. Do we go with layering/chaining? Data-oriented messaging, caching, what other activities can happen in the HLStorage layer"
[15:20] <cwilper> "Suggest representing the HLStorage roadmap into components"
[15:21] <cwilper> Chris: "Could use Components in JIRA, not sure about sub-components, but we could fake them"
[15:28] <cwilper> Aaron: "Should we have a Component for changes to Fedora that may be necessary"
[15:28] <cwilper> Chris; "Important to identify when that's the case"
[15:29] <cwilper> Dan: "Design needs to be informed by things like, how Fedora is used as a storage resource itself"
[15:30] <cwilper> Chris: "Does that mean 'effect on Fedora' category makes sense"
[15:30] <cwilper> Dan: "Yes."
[15:31] <cwilper> Chris: "Effect on Fedora? as category name"
[15:33] <cwilper> Dan: "Suggest using Wiki for design-oriented tasks prior to getting to rigid with JIRA"
[15:33] <cwilper> Aaron: "Let's switch to -How to proceeed-"
[15:34] <cwilper> "Use Future Special Topics mtgs for this, or Special interest groups for this"?
[15:34] * mdiggory wants to toss out a tangent.... https://wiki.duraspace.org/display/FCREPO/High+Level+Storage?focusedCommentId=22024650#comment-22024650
[15:36] <cwilper> Thanks Mark...interesting to consider.
[15:37] <cwilper> Chris: "I like the idea of splitting off into interest groups for reasons Aaron mentioned"
[15:38] <cwilper> "(Timing and the fact that it might dominate the committer mtgs)"
[15:39] <cwilper> Aaron: "Communication on dev list? Concern: too much traffic"
[15:39] <cwilper> Chris: "Traffic=good"
[15:41] <cwilper> Dan: "+1 on keeping discussion on the list. People could filter"
[15:41] <cwilper> Steve: "+1 on dev list"
[15:42] <cwilper> Asger: "Lots of opinions on design and not a lot on how we carry out the design"
[15:42] <eddies> (afk)
[15:42] <cwilper> s/carry out the design/carry out the discussion/g
[15:43] <cwilper> Aaron: "Fedora Object Model is a good area to start with. Let's identify the sub-issues."
[15:44] <cwilper> "In general, make sure we have the items listed under each topic"
[15:51] * mdiggory (~mdiggory@ip72-199-217-116.sd.sd.cox.net) Quit (Quit: mdiggory)
[15:57] * mdiggory (~mdiggory@ip72-199-217-116.sd.sd.cox.net) has joined #duraspace
[16:01] <cwilper> (brainstorming sub-areas under "Fedora Object Model")
[16:02] <cwilper> So far:
[16:02] <cwilper> * Versioning
[16:02] <cwilper> * Audit Trail
[16:02] <cwilper> * Separating the kind of Content (XML vs non-XML) from where you store it ("Inline XML?")
[16:03] <cwilper> * Extensibility of Object Properties vs just using RELS-EXT/INT
[16:04] <cwilper> * What convenience methods, if any, should be in the new DigitalObject interface for things we normally categorize as "semantic" (e.g. the hasModel relation?)
[16:04] <Asger> Suggestion: Content Model Semantics
[16:05] <Asger> Ie. semantics that allows applications to reflect on there stuff goes in the object
[16:13] <cwilper> Aaron: "Reading mdiggory's post...let's step back and see the thinking and see what's applicable. Want to understand conclusions."
[16:14] <mdiggory> I wish I could be in the call, but I'm stuck on the phone now... will need to followup afterward... sorry...
[16:16] <cwilper> Ok, Mark, it sounds like it'd be useful to have you in on (at least) a future discussion where we talk about the DigitalObject interface.
[16:19] <cwilper> Aaron: "Who's interested in this particular sub-topic. (Chris, Asger, probably more)..I'm inclined to put this as an item under the Fedora Object Model thread of interest"
[16:19] <cwilper> (continuing with list):
[16:20] <sbayliss> I have to leave right now unfortunately, looking forward to discussing further on the list etc
[16:20] <cwilper> * Understand DSpace2 modeling decisions and how they apply to the new Fedora DigitalObject thinking (see if mdiggory can be on a call sometime soon to help us understand this a bit better)
[16:22] <sbayliss> (I have posted to the committers list re the up-coming release status)
[16:25] <cwilper> Eddie: "caught tail end of discussion re:diggory's post. i'm interested in whole-object versioning and required relationships in a content model"
[16:26] <Asger> My summary of Eddie: Regarding a set of Fedora Objects as a Fedora Record, or some sort of combined resourse
[16:27] <Asger> We have actually worked on that issue
[16:28] <Asger> In Enhanced Content Model
[16:42] <eddies> (must run)
