I've wondered the same thing. For example,
integers have to be xsd:integer and not xsd:int. Yet servers based on traditional
RDBMs will probably use 32 bit integers and xsd:int is a better fit for
the data. If the intent was to keep to well-defined standard data types,
why not support more, most, or perhaps all xsd data types?
Perhaps others who served on OSLC longer
can shed light on the background of that decision.
David.

Dealing with unsupported literal value types
Sent by:
<oslc-core@lists.oasis-open.org>
Core 3.0 specifies a closed set of data types for literals
[1].
Is there any advice/suggestion on how an implementation should deal with
resources and their shapes when other data types are involved?
For example, I work on an application that uses xsd:duration internally,
and currently the OSLC representations of that type is identical and hence
non-compliant. We could (i) live with this non-compliance, (ii) refrain
from exposing resources of such types on the OSLC API, or (iii) pick some
other data type that is supported and map values into that supported type.
For (iii) xsd:string comes to mind.
What is the preferred approach?
As an aside, I don't recall the design rationale that led to a closed set
of data types, which leads me to question that decision. Should Core
be less prescriptive and leave the set of types open?
