[OASIS Issue Tracker] Commented: (ODATA-256) Simplify numeric data types

[OASIS Issues Tracker <workgroup_mailer@lists.oasis-open.org>]

    [ http://tools.oasis-open.org/issues/browse/ODATA-256?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=32649#action_32649 ] 

Michael Pizzo commented on ODATA-256:
-------------------------------------

The latest proposal appears to be introducing an "abstract" type that can be applied in some places (i.e., vocabularies) but not others (i.e., properties). While I like the idea, the fact that we use ComplexType in both term definitions and models makes it difficult to enforce restrictions based on the usage.

There are other cases where we've recently added "abstract" typeslike Edm.PrimitiveType, Edm.ComplexType, and Edm.EntityType and had to define rules around what could be used in each of the different contexts.

Before adding more special-use types, I'd like to see if we can rationalize all of these with some easy to understand rules about what types can be used where.

> Computer history has provided us with a growing number of numeric data types, and quite a few of them are reflected in Edm primitive types.
> Integer types:
> - Byte (0..2^8)
> - SByte
> - Int16
> - Int32
> - Int64
> - Decimal Scale=0
> Fixed-point types
> - Decimal with VariableScale="false", see ODATA-76
> Floating-point types
> - Decimal with VariableScale="true", see ODATA-76
> - Single
> - Double
> Especially for defining vocabularies it would be helpful to have an abstract type Edm.Number that can be applied to any of the numeric primitive types.
