Re: [oslc-core] Meeting minutes 19-Feb-2015

["Lonnie VanZandt" <lvanzandt@sodius.com>]

If your drawings are relatively to the point (i.e. not governmental architecture framework diagrams) and you are not attempting to build a referentially consistent model repository then I can recommend yUml (see http://yuml.me/) as a convenient tool and DSL to sketch UML-like object-relational diagrams.

For example, taken from their site, try this URL

http://yuml.me/diagram/scruffy/class/[note: You can stick notes on diagrams too!{bg:cornsilk}],[Customer]<>1-orders 0..*>[Order], [Order]++*-*>[LineItem], [Order]-1>[DeliveryMethod], [Order]*-*>[Product], [Category]<->[Product], [DeliveryMethod]^[National], [DeliveryMethod]^[International]

If we are seeking a modeling tool then don’t settle for a drawing tool. That is like loaning money at negative interest rates: penny-wise and pound-foolish.

Roll Call

[07:03] Steve Speicher (IBM): Agenda: https://wiki.oasis-open.org/oslc-core/Meetings/Telecon2015.02.19

[07:06] Steve Speicher (IBM): Regrets: Arnaud, Arthur, Ian, Martin S

[07:06] Steve Speicher (IBM): Attendees: David Green (Tasktop Technologies) Martin Pain (IBM) Nick Crossley (IBM) Samuel Padgett (IBM) Steve Speicher (IBM)

[07:08] Harish (Software AG): Harish joining in.

[07:14] Steve Speicher (IBM): Attendees: + Harish (Software AG)

[07:08] David Green (Tasktop Technologies): David Green to scribe

[07:08] Steve Speicher (IBM): https://wiki.oasis-open.org/oslc-core/Meetings/Telecon2015.02.05

[07:10] David Green (Tasktop Technologies): Approval of previous meeting minutes: no objections, approved

Diagramming Tools

[07:14] David Green (Tasktop Technologies): Discussion about diagraming tools, no decision

Steve Speicher: Looking to find a good simple free diagramming tool for specification author and general maintenance. Often times spec authors use proprietary tool and generate PNG, makes are for others to update.

David Green: not really endorsing any tools, though draw.io is a basic service that has used before

Nick Crossley: has used ArgoUML as well

Spec Progress

[07:14] Steve Speicher (IBM): Discovery: http://tools.oasis-open.org/version-control/browse/wsvn/oslc-core/specs/discovery.html

[07:17] David Green (Tasktop Technologies): Link relation header: should we put in a known predicate? Client reading feed could add a triple that uses the standard predicate.

[07:18] Steve Speicher (IBM): PROPOSED: Use a standard predicate for feeding indexes based on link relationship type: <http://open-services.net/ns/core#creationType>;

[07:21] David Green (Tasktop Technologies): No objections to using header

[07:22] David Green (Tasktop Technologies): Section 5.3 of Discovery: reusing LDP term "Constrained By" that takes a container - link relation to URI that describes constraints.

[07:22] David Green (Tasktop Technologies): Could be resource shapes, could be HTML page, etc.

[07:22] David Green (Tasktop Technologies): proposal to use a new term rather than LDP term

[07:22] Steve Speicher (IBM): PROPOSED: define a shape-specific relationship type, such as oslc:creationShape

[07:30] Martin Pain (IBM): The LDP spec says: " LDP servers MUST publish any constraints on LDP clients ability to create or update LDPRs, by adding a Link header with an appropriate context URI, a link relation of http://www.w3.org/ns/ldp#constrainedBy, and a target URI identifying a set of constraints [RFC5988], to all responses to requests that fail due to violation of those constraints."

[07:30] Martin Pain (IBM): "The same Link header MAY be provided on other responses."

[07:32] Steve Speicher (IBM): Leaning towards using oslc:creationConstrainedBy rel type

[07:35] David Green (Tasktop Technologies): Delegated dialog: conformance section largely the same, doesn't mention window name

[07:36] David Green (Tasktop Technologies): requesting feedback: cardinality, required fields

[07:36] David Green (Tasktop Technologies): can we reuse same shape with statement "server must not reject prefill request because it's missing required fields", or change shape so that no fields are required

[07:37] David Green (Tasktop Technologies): Steve: advise on not rejecting request approach

[07:37] David Green (Tasktop Technologies): benefit with shape reuse

[07:39] Martin Pain (IBM): https://wiki.oasis-open.org/oslc-core/DelegatedUIUseCases

[07:43] David Green (Tasktop Technologies): request for reviewers

[07:44] David Green (Tasktop Technologies): Samuel to assist

[07:46] David Green (Tasktop Technologies): Common vocabulary: review feedback received

[07:46] Steve Speicher (IBM): http://tools.oasis-open.org/version-control/browse/wsvn/oslc-core/specs/common-vocab.html

[07:59] David Green (Tasktop Technologies): Martin proposing to contribute ...(what?)

[08:01] Martin Pain (IBM): Martin will contribute Actions 2.0 as the basis for Actions 3.0

[08:01] David Green (Tasktop Technologies): Thanks Martin

[08:01] Martin Pain (IBM): Martin also noted that the Automatino TC will be meeting to discuss whether & how to proceed with Automation 3.0

Meeting Adjourned
