Subject: [OASIS Issue Tracker] (ODATA-1067) Consider ability to define computed default values
[ https://issues.oasis-open.org/browse/ODATA-1067?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Ralf Handl updated ODATA-1067: ------------------------------ Fix Version/s: (was: V4.01_CS02) (was: V4.0_ERRATA04) > Consider ability to define computed default values > -------------------------------------------------- > > Key: ODATA-1067 > URL: https://issues.oasis-open.org/browse/ODATA-1067 > Project: OASIS Open Data Protocol (OData) TC > Issue Type: Bug > Components: CSDL JSON , CSDL XML, Vocabularies > Affects Versions: V4.01_WD01 > Reporter: Michael Pizzo > Fix For: V5.0_WD01 > > > Currently, default values for properties and (now, as of ODATA-1066) parameters are static values. > There are some cases where the default value may be the result of a calculation. Examples: > 1) The value of a related property/parameter > 2) An expression based on the value of one (or more) related properties/parameters > 3) The result of invoking a function(import) on the service (with params?) > Issues: > -how to express the value of the defaultvalue (use Edm.Untyped? -- this could only be supported in 4.01) > -what is the syntax of the expression? > -can it invoke a funciton(import) and, if so, how are parameters passed? > For parameters, could define a derived OptionalParameterType that has a DefaultValueExpression that is Edm.Untyped and only returned as that derived type in a 4.01 payload. -- This message was sent by Atlassian JIRA (v6.2.2#6258)
