[08:04] Matt Rutkowski (IBM): Called to order 10:04
[08:05] Matt Rutkowski (IBM): Move to approve 2013-01-28 minutes, 2nd Richard, no objs
[08:06] Matt Rutkowski (IBM): Paul not on, need status on Guidance document as CSP, Matt to follow-up
[08:07] Matt Rutkowski (IBM): Dale: update on new additions to guidance document
[08:08] Matt Rutkowski (IBM): Dale: implementors are struggling with IDs, QNames from spec.
[08:09] Matt Rutkowski (IBM): Dale: perhaps need to be in spec. but good for guidance doc.
[08:10] Matt Rutkowski (IBM): Dale: spent 10-20 hours just figuring out how to use these elements to traverse model/graph
[08:10] Matt Rutkowski (IBM): Dale: Should vendor types lock u into their artifact references?
[08:10] Matt Rutkowski (IBM): Dale: we need to address maintenance of documents so they can truly be reused
[08:11] Matt Rutkowski (IBM): Dale: tooling could insulate users from some of this
[08:11] Matt Rutkowski (IBM): Paul joined
[08:11] Paul Lipton (Co-Chair) C: Hi, I'm in two meetings. I can join for limited time.
[08:14] Matt Rutkowski (IBM): Matt: need to address 2 areas frm Dale's experience: 1) traversal of nodes/model using schema attributes 2) order of processing relationship types (dependencies)
[08:17] Matt Rutkowski (IBM): Thomas: schema and spec reorg around wd13 or 14
[08:17] Matt Rutkowski (IBM): Thomas: separation of impls
[08:22] Matt Rutkowski (IBM): Paul: in regard to changing guidance doc from CND to CSP, was travelling and wanted some more discussion, we agree its on the standards track
[08:24] Matt Rutkowski (IBM): Matt: IMO, prefers not to wait, Paull will submit request
[08:28] Matt Rutkowski (IBM): Matt: use of term tier
[08:28] Matt Rutkowski (IBM): Dale: thought of clustering
[08:30] Matt Rutkowski (IBM): Derek: used to apply component to a topolgy, not related to grouping of concerns (not layering)
[08:37] Matt Rutkowski (IBM): Derek: frame of ref. is topological; dont care about relationships or composition of components
[08:37] Matt Rutkowski (IBM): Derek: concerned with topological placement
[08:38] Matt Rutkowski (IBM): Derek: separate bw topological thinking (placement of things) vs. groups of components that work as an ensemble
[08:39] Matt Rutkowski (IBM): Derek: Take tier and make sure does not take on "role" concept
[08:40] Matt Rutkowski (IBM): Derek: is more the pesonality of the infrastructure
[08:40] Matt Rutkowski (IBM): Derek: web tier does not even mean (its just a type); its just a group of componenents that reside on same part of topology
[08:41] Matt Rutkowski (IBM): Dale: impl. question... if we make it topological, is it poss. to have relationships bw node tepmlates and tiers?
[08:42] Matt Rutkowski (IBM): Derek: is a node type that can host a some other node types
[08:42] Matt Rutkowski (IBM): Derek: a tier contains one kind of node, and that node has inside its allowed components
[08:43] Matt Rutkowski (IBM): Derek: depends on how u model it semantically
[09:00] Matt Rutkowski (IBM): Matt moves to adjourn, Thomas 2nds, mtg adjourned
[09:01] Matt Rutkowski (IBM): Matt: Derek agreed to update TOSCA-60 with his definition for "tier" (or a name to be selected later)
