5.1.5 ODATA-1066 - Consider supporting optional operation parameters

Mike: Example of applying annotation:

<?xml version="1.0" encoding="utf-8"?>
 <edmx:Edmx Version="4.0" xmlns:edmx="http://docs.oasis-open.org/odata/ns/edmx">
    <Schema Namespace="test" xmlns="http://docs.oasis-open.org/odata/ns/edm">
      <Function Name="TestFunction">
        <Parameter Name="param" Type="Edm.String" />
        <Parameter Name="requiredParam" Type="Edm.String" />
        <Parameter Name="optionalParam" Type="Edm.String">
          <Annotation Term="Org.OData.Core.V1.OptionalParameter" />
        <Parameter Name="optionalParamWithDefault" Type="Edm.String">
          <Annotation Term="Org.OData.Core.V1.OptionalParameter">
              <PropertyValue Property="DefaultValue" String="Smith" />
        <ReturnType Type="Edm.Boolean" />
      <EntityContainer Name="Default">
        <FunctionImport Name="TestFunction" Function="test.TestFunction" />

Mike: Better:

"<edmx:Edmx xmlns:edmx=\"http://docs.oasis-open.org/odata/ns/edmx\" Version=\"4.0\">" +
  "<edmx:DataServices>" +
    "<Schema xmlns=\"http://docs.oasis-open.org/odata/ns/edm\" Namespace=\"test\">" +
      "<Function Name=\"TestFunction\">" +
        "<Parameter Name = \"param\" Type=\"Edm.String\"/>" +
        "<Parameter Name = \"requiredParam\" Type=\"Edm.String\">" +
            "<Annotation Term=\"Org.OData.Core.V1.OptionalParameter\">" +
              "<Record>" +
                "<PropertyValue Property=\"IsOptional\" String=\"false\"/>" +
              "</Record>" +
            "</Annotation>" +
        "</Parameter>" +
        "<Parameter Name = \"optionalParam\" Type=\"Edm.String\">" +
            "<Annotation Term=\"Org.OData.Core.V1.OptionalParameter\"/>" +
        "</Parameter>" +
        "<Parameter Name = \"optionalParamWithDefault\" Type=\"Edm.String\">" +
            "<Annotation Term=\"Org.OData.Core.V1.OptionalParameter\">" +
              "<Record>" +
                "<PropertyValue Property=\"DefaultValue\" String=\"Smith\"/>" +
              "</Record>" +
            "</Annotation>" +
        "</Parameter>" +
        "<ReturnType Type=\"Edm.Boolean\"/>" +
      "</Function>" +
      "<EntityContainer Name=\"Default\">" +
        "<FunctionImport Name=\"TestFunction\" Function=\"test.TestFunction\"/>" +
      "</EntityContainer>" +
    "</Schema>" +
  "</edmx:DataServices>" +

Hubert: having an IsOptional property with value false in an annotation named OptionalParameter is confusing

Mark: Agrees

Ralf: I also agree, had that qualm when applying the issue

George: Does not see this as a problem

Mike: as application of issue differs from resolution, we need to capture this change

George: I move to approve. Hubert seconds


Mike: I move to amend the motion to include the fact that, in the application, we have explicitly omitted the IsOptional property of the OptionalParameterType. Hubert seconds


Ralf,Mike: Motion to amend the motion passes

Ralf,Mike: amended motion passes, ODATA-1066 is CLOSED as applied

George: Move to approve resolution to ODATA-1084

5.2 Issues to resolve for V4.01 CSD02

5.2.1 ODATA-1084 - Rule searchWord is too restrictive

Ralf: ODATA-1084 is OPEN

George: I move to approve resolution to ODATA-1084. Mark seconds.

Ralf: ODATA-1084 is RESOLVED as proposed and applied

5.3 Issues to close for V4.01 CSD02

  1. ODATA-890 - Specify how to get from a JSON message to a JSON schema for validating this message
  2. ODATA-902 - 4.5.2: make "annotations" a hash-map with the target as key
  3. ODATA-907 - Consider Swagger for describing OData metadata in JSON format (public comment c201602e00000)
  4. ODATA-910 - Consider format that is tailored for programmatic access (public comment c201602e00002)
  5. ODATA-911 - Miscellanous feedback (public comment c201602e00003)
  6. ODATA-914 - Comments from OASIS Technical Advisory Board (TAB)
  7. ODATA-1066 - Consider supporting optional operation parameters
  8. ODATA-1084 - Rule searchWord is too restrictive

Hubert: I move we accept the reviewed changes in OData 4.01 Part I: Protocol and associated ABNF construction rules, OData Common Schema Definition Language JSON Representation, and the OData Core vocabulary and close the following corresponding issues as applied: ODATA-890, ODATA-902, ODATA-907, ODATA-910, ODATA-911, ODATA-914, ODATA-1066, and ODATA-1084. George seconds.

Ralf: No objections, motion passes

5.4 Publish documents

5.4.1 Motion to publish Part 1 and Part 2

Hubert: I move that the TC approve OData V4.01 Working Draft 02 and all associated artifacts packaged together in https://www.oasis-open.org/committees/download.php/61031/odata-v4.01-csd02-2017-06-21.zip as Committee Specification Draft 02 and designate the Microsoft Word version of the specification as authoritative. I further move that the TC approve submitting the aforementioned Committee Specification Draft 02 for 30 days of public review. George seconds.

Ralf: No objections, motion passes
