a.Document Walkthrough

i.OData CSDL JSON Representation Version 4.01 as of 2017-02-15

[17:08] Ralf Handl (SAP SE): $kind -> $Kind for consistency

 

[17:08] Mike Pizzo: knock knock -- can someone let me in to the adobe connect?

[17:08] Mike Pizzo: Thank you! 

 

[18:21] Ralf Handl (SAP SE): Considered changes:

[18:21] Ralf Handl (SAP SE): - Nest types under schema, identify them by unqualified name

[18:21] Ralf Handl (SAP SE): - allow aliases for annotations and within $Type values

[18:22] Ralf Handl (SAP SE): Decided changes:

[18:22] Ralf Handl (SAP SE): $kind --> $Kind

[18:22] Ralf Handl (SAP SE): $isCollection --> $IsCollection

[18:23] Ralf Handl (SAP SE): 6.V4.01 [9:20 am PT]

a.Issues for V4.01_CSD02 ready for resolution

[18:23] Ralf Handl (SAP SE): i.ODATA-1028 4.3.4 and 4.4: clarify resolution of relative URLs in system query option $id

[18:23] Ralf Handl (SAP SE): Just realized that 4.3.4 contradicts 4.4, http://docs.oasis-open.org/odata/odata/v4.01/csprd01/part2-url-conventions/odata-v4.01-csprd01-part2-url-conventions.html#_Toc470093604: 

The entity-id specified by $id may be expressed absolute or relative to the request URL. 

So we have two different resolution mechanisms for the $id system query option: 

- relative to the service root for paths containing /$entity 

- relative to the request URL for paths ending in /$ref 

This is less than consistent.

[18:25] Ralf Handl (SAP SE): Source of problem:

[18:25] Ralf Handl (SAP SE): http://host/service/$entity?$id=Products(0)

[18:26] Ralf Handl (SAP SE): http://host/service/$entity/this.VipProducts?$id=Products(0)

[18:26] Ralf Handl (SAP SE): http://host/service/$entity/this.VipProducts?$id=../Products(0)

[18:28] Ralf Handl (SAP SE): DELETE http://host/service/Categories(1)/Products/$ref?$id=../../Products(0)

[18:30] Ralf Handl (SAP SE): DELETE http://host/service/Categories(1)/Products/$ref?$id=/service/Products(0)

 

[18:32] Mike Pizzo: could also do http://host/service/$entity/this.VipProducts?$id=/service/Products(0)

 

[18:40] Hubert Heijkers (IBM)1: I move to resolve ODATA-1028 as proposed.

 

[18:40] Ralf Handl (SAP SE): ... in this discussion, contrary to the proposal in the issue

 

[18:42] Mike Pizzo: updated proposal in issue: Clarify that relative URLs passed with query option $id are relative to the path to be consistent with $ref.

 

[18:43] Hubert Heijkers (IBM)1: I move to resolve ODATA-1028, once again, as per the updated proposal.

 

[18:44] Martin Zurmuehl (SAP SE): I second

 

[18:44] Ralf Handl (SAP SE): ODATA-1028 is resolved again

[18:44] Ralf Handl (SAP SE): b.Issues for V4.01_CSD02 in New or Open state without concrete proposal

[18:44] Ralf Handl (SAP SE): vii.ODATA-920 Specify overflow for int data types (-INF, INF, NaN)

 

[18:47] Mike Pizzo: Proposal:

[18:47] Mike Pizzo: 1) Because annotating numeric values of arrays is problematic, and we are no longer trying to use JSON Schema as our schema language, revert application of the numericValueException annotation and continue the 4.0 literal "INF", "-INF", and "NaN" values.

2) Support these values all numeric types.

3) Support -INF and INF for Edm.Date and Edm.DateTimeOffset --> OData Temporal Extension

[18:49] Mike Pizzo: I move we resolve ODATA-920 as proposed.

 

[18:50] Mark Biamonte (Progress): I second

 

[18:50] Ralf Handl (SAP SE): ODATA-920 is resolved with the revised proposal

[18:51] Ralf Handl (SAP SE): 7.Next meeting [9:50 am PT]

a.Thursday February 23, 2017 during 8-10 am PST?

[18:52] Ralf Handl (SAP SE): Mike and Hubert can't make next week

[18:53] Ralf Handl (SAP SE): Let's try next week

[18:54] Ralf Handl (SAP SE): Meeting after that on March 02, 2017, 8-10 PST

[18:54] Ralf Handl (SAP SE): 8.AOB and wrap up [9:55 am PT]

[18:55] Ralf Handl (SAP SE): Mike: JSON format for batch requests and responses

[18:57] Ralf Handl (SAP SE): Mike to send around a proposal and open an issue to track it

[18:59] Ralf Handl (SAP SE): Meeting is adjourned
