GMT-08:00
[07:08] Nick Crossley (IBM): List of attendees:
David Honey (Persistent/IBM), Jim Amsden (IBM), Martin Sarabura (PTC),
Nick Crossley (IBM)
[07:08] Martin Sarabura (PTC): Martin will
scribe
[07:08] Martin Sarabura (PTC): Review minutes
[07:08] Nick Crossley (IBM): https://wiki.oasis-open.org/oslc-ccm/Meetings/Telecon2017.03.23
[07:08] Martin Sarabura (PTC): Approved
[07:09] Martin Sarabura (PTC): Action items:
Pending to get list of relationships, still pending
[07:09] Martin Sarabura (PTC): Review issue
36 - notes posted
[07:10] Martin Sarabura (PTC): CM: Last
time reviewed comments, Jim was going to update spec
[07:10] Martin Sarabura (PTC): Jim unable
to finish
[07:11] Martin Sarabura (PTC): Other changes
pending related to templates
[07:13] Martin Sarabura (PTC): Need to decide
on how much we should restate core requirements
[07:13] Martin Sarabura (PTC): Or, just
the delta from core?
[07:15] Martin Sarabura (PTC): Convenient
to have everything in one place - core doesn't have equivalent list
[07:17] Martin Sarabura (PTC): CM structure
partly to drive automated test tools
[07:18] Martin Sarabura (PTC): Sam Padgett
wrote original spec and it hasn't been altered much
[07:18] Martin Sarabura (PTC): structurally,
anyway
[07:19] Martin Sarabura (PTC): CM probably
pretty similar to RM - mostly just vocabularies
[07:20] Martin Sarabura (PTC): If we could
create a single boilerplate then we would publish just the deltas
[07:20] Martin Sarabura (PTC): No MUSTs
in core, so every domain spec pretty much need to indicate what is required
[07:22] Martin Sarabura (PTC): What is repeated
is a subset of core anyway - mostly the MUSTs
[07:23] Martin Sarabura (PTC): Jim: don't
really care if it is redundant or not - will take more work to check. Different
if we're doing 7 or 8 specs however
[07:25] Martin Sarabura (PTC): Easier to
decide what the domain wants if you start with a core list rather than
a cm list
[07:25] Martin Sarabura (PTC): Nice if table
indicates what is a deviation from core
[07:27] Martin Sarabura (PTC): Query not
in the list of domain specs to bring forward - should add it
[07:27] Martin Sarabura (PTC): Martin to
raise issue
[07:28] Martin Sarabura (PTC): Nick already
has some changes, will check in then Jim will make his changes
[07:29] Martin Sarabura (PTC): Jim: Domain
specs shapes partially done, will be checking in soon
[07:29] Martin Sarabura (PTC): Nick notify
team if there are bits we should bring back into the cm spec
[07:30] Martin Sarabura (PTC): based on
what he is doing in domains
[07:31] Martin Sarabura (PTC): Jim has some
changes to cm - he will check in asap
[07:32] Nick Crossley (IBM): Other action
item for Nick DONE - raise request for IBM's RTC Change Management implementation
to be compliant with OSLC Actions 2.0: https://jazz.net/jazz/resource/itemName/com.ibm.team.workitem.WorkItem/112801
[07:33] Martin Sarabura (PTC): Mainly need
to add discoverability of actions
[07:33] Martin Sarabura (PTC): Are discoverable
using a completely different api
[07:34] Martin Sarabura (PTC): Very difficult
to figure that out if you don't know the syntax
[07:35] Martin Sarabura (PTC): Almost ready
for public review - just Nick's stuff blocking now
[07:36] Martin Sarabura (PTC): Jim changes
checked in
[07:37] Martin Sarabura (PTC): Config management
[07:37] Nick Crossley (IBM): https://issues.oasis-open.org/browse/OSLCCCM-36
[07:38] Martin Sarabura (PTC): Change sets
intended to be minimal - didn't want to constrain too much
[07:39] Martin Sarabura (PTC): Not many
examples to use as references for change sets
[07:39] Martin Sarabura (PTC): Don't have
well defined change set lifecycle or even good model for how to represent
multiple change sets and how applied to stream
[07:40] Martin Sarabura (PTC): What are
the assumptions about multiple change sets, change set dependencies?
[07:41] Martin Sarabura (PTC): Spec is silent
on these questions
[07:42] Martin Sarabura (PTC): Can a change
set be delivered only to one stream, or can it be delivered to more than
one?
[07:43] Martin Sarabura (PTC): What Nick
needs from TC is overall sense for how detailed we want to get
[07:43] Martin Sarabura (PTC): Life cycle?
Dependencies?
[07:44] Martin Sarabura (PTC): Eg., was
derived from indicates dependence, do we want to back off even from thhat/
[07:45] Martin Sarabura (PTC): Can we leverage
existing standards? eg., Delta V, MOF, or WVCM
[07:46] Martin Sarabura (PTC): Nick: Delta-V
and WVCM biased towards file-based (we want resource-based)
[07:46] Nick Crossley (IBM): WVCM - web
version control management or something
[07:46] Martin Sarabura (PTC): Delta V focus
on distributed development also
[07:46] Jim Amsden (IBM): http://www.webdav.org/deltav/protocol/rfc3253.html#PROPERTY_activity-version-set
[07:47] Nick Crossley (IBM): WVCM was a
Java API proposal, back in the Java 4-5 days as I recall
[07:48] Jim Amsden (IBM): http://d3s.mff.cuni.cz/publications/download/HnetynkaPlasil-MOF.pdf
[07:49] Martin Sarabura (PTC): Action: TC
to think about how prescriptive we want to get - or what level of detail
we want to discuss - on the subject of change sets
[07:49] Martin Sarabura (PTC): Nick feels
we need to give change sets more thought before we can resolve issue 36
[07:50] Jim Amsden (IBM): OMG MOF Versioning
and Development Lifecycle Specifcation: http://www.omg.org/cgi-bin/doc?formal/07-05-01.pdf
[07:51] Martin Sarabura (PTC): One possible
resolution is to undeprecate oslc:configmutable
[07:52] Martin Sarabura (PTC): oslc_config:mutable
[07:55] Martin Sarabura (PTC): Jim: MOF
versioning does not address ability to difference change sets
[07:55] Martin Sarabura (PTC): Removed red
text from earlier changes
[07:56] Nick Crossley (IBM): No other business
[07:56] Nick Crossley (IBM): Meeting adjourned
