a.Action items due

i.None

[17:06] Ralf Handl (SAP SE): 5.Version 4.01 Public Review - 05 July 2017 to 03 August 2017 [8:20 am PT]

a.Issues

[17:06] Ralf Handl (SAP SE): ii.ODATA-1102 Multiplication and division of Edm.Decimal: result has floating scale if either operand has floating scale

[17:08] Ralf Handl (SAP SE): Proposal: Floating scale dominates, then variable scale, then fixed scale.

[17:09] Hubert Heijkers (IBM): I move to resolve ODATA-1102 as proposed

[17:09] Michael Pizzo: I second

[17:09] Ralf Handl (SAP SE): ODATA-1102 is RESOLVED as proposed

[17:10] Ralf Handl (SAP SE): iv.ODATA-1107 Introduce instance annotation to specify which types an instance "implements"

[17:11] anonymous1 morphed into Matt Borges (SAP)

[17:13] Michael Pizzo: I proposed moving ODATA-1107 to 4.02.

[17:13] Ralf Handl (SAP SE): No objection, moved

[17:13] Ralf Handl (SAP SE): v.ODATA-1108 Disallow empty parens for implicit parameter syntax

[17:14] anonymous1 morphed into George Ericson (Dell)

[17:16] Ralf Handl (SAP SE): ODATA-1108 is OPEN

[17:23] Michael Pizzo: I propose we resolve ODATA-1108 as proposed.

[17:23] Hubert Heijkers (IBM): I second

[17:23] Ralf Handl (SAP SE): ODATA-1108 is RESOLVED as proposed

[17:24] Ralf Handl (SAP SE): vi.ODATA-1109 Clarify that 'parameter' aliases can also be used to substitute expressions

[17:27] Michael Pizzo: Draft Proposal: Query parameters for $filter segment are always expressions.  All other parameters are treated as literals.

[17:45] Michael Pizzo: Hubert calls out that the last example (taking the input 1&$expand=Orders) is a general issue.  We should provide general guidance that, when taking input from a user, must make sure it is the expected type; for example, make sure there are no unescaped '&'.

[17:52] Michael Pizzo: Clarified proposal: Query parameters for $filter segment are always passed in as expressions. All other parameters are evaluated and passed as literals.

[17:55] Michael Pizzo: Added new issue for Securing OData: https://issues.oasis-open.org/browse/ODATA-1110

[17:55] George Ericson (Dell): I'm wondering whether we could insist that the segment be a complete _expression_, rather than 'part' of an _expression_.

[17:56] Michael Pizzo: Issue: Customers?$filter=Orders($filter=ShipTo eq @a)&@a=City

[18:00] Hubert Heijkers (IBM): Can one do this: Customers?$filter=Orders($filter=ShipTo eq @a;@a=City)

[18:00] George Ericson (Dell): Can one do this: Customers?$filter=Orders($filter=ShipTo eq City)

[18:00] Ralf Handl (SAP SE): Customers(ID=@c)/Orders(ID=@o)?@c=ID&@o=45

[18:02] Michael Pizzo: Customers/GetById(id=@id)?@id=1

[18:02] Ralf Handl (SAP SE): @Hubert: no, nested option syntax with semicolons doesn't allow nested aliases

[18:05] Michael Pizzo: Customers?$fitler=id eq @id?@id=1

[18:06] Michael Pizzo: Customers?$filter=id eq @id&@id=1

[18:07] Michael Pizzo: Customers/GetById(id=@id)?@id=Manager/BestEmployee()/Id

[18:09] Michael Pizzo: (that example was invalid...)

[18:13] Ralf Handl (SAP SE): Parameter aliases allow the same value to be used multiple times in a request and may be used to reference primitive values, complex, or collection values.

[18:14] Ralf Handl (SAP SE): products/ByColors(colors=@c)?@c=["red',"green","blue"]

[18:17] Ralf Handl (SAP SE): products/ByColors(colors=@c)?@c=$root/My/Preferences/Colors

[18:23] Michael Pizzo: Customers?$filter=Orders($filter=ShipTo eq @a)&@a=City

[18:24] Ralf Handl (SAP SE): Customers(ID=@c)/Orders(ID=@o)?@c=ID&@o=45

[18:30] Ralf Handl (SAP SE): Customers(ID=@c)/Orders(ID=@c)?@c=FirstName&@o=45

[18:30] Ralf Handl (SAP SE): Customers(ID=@c)/Orders(ID=@o)?@c=FirstName&@o=45

[18:31] Ralf Handl (SAP SE): Customers(ID=42)/some.function(par1=FirstName)/...

[18:33] Ralf Handl (SAP SE): Customers(ID=42)/some.function(par1=@p)/...?@p=FirstName

[18:37] Ralf Handl (SAP SE): Hubert, Ralf: tend to have _expression_ evaluated at point where it is used. In last example evaluation should not depend on subsequent path segments ...

[18:38] Ralf Handl (SAP SE): Mike: tends to have _expression_ evaluated in the context of the last path segment

[18:38] Ralf Handl (SAP SE): i.ODATA-1100 Add mechanism for specifying match type for $search

[18:39] Ralf Handl (SAP SE): Mike suggests to skip that one

[18:39] Ralf Handl (SAP SE): iii.ODATA-1105 Simplify selection of properties of complex type

[18:40] Michael Pizzo: $select=Address/City,Address/State

[18:40] Michael Pizzo: $select=Address($select=City,State)

[18:41] Michael Pizzo: $select=Addresses($select=City,State;$filter=Country eq 'UK')

[18:50] Hubert Heijkers (IBM): $select=ComplexProp($filter=PropA eq 'foo')&$expand=ComplexProp/NavProp1($select=a,b)

[18:52] Hubert Heijkers (IBM): $select=ComplexProp($filter=PropA eq 'foo';$expand=NavProp1($select=a,b))

[18:53] Michael Pizzo: Customers?$select=Addresses($filter=Country eq 'UK')&$expand=Addresses/Occupant($select=Name)

[18:55] Michael Pizzo: Customers?$select=Addresses($expand=Occupant) same as Customers?$expand=Addresses/Occupant ?

[18:56] Ralf Handl (SAP SE): same as Customers?$select=Addresses&$expand=Addresses/Occupant
