Re: [ontolog-forum] URIs [was: Truth]

OMG URIs are not designed to be de-referencable in the Linked Data sense.

Matthew,

ISO standards aren't very good at providing URIs. I was hoping to

hear some specific recommendations, such as:

http://schema.omg.org/spec/UML/2.1/uml.xml:UnlimitedNatural

http://schema.omg.org/spec/UML/2.1/uml.xml:Boolean

Both of those URIs 404. Are they supposed to be de-referenced?

Matthew,

I completely agree with you, and would be interested to hear from

this

group what they believe are authoritative URIs for common data types

such

as:

Float (or Real)

Integer

Boolean

String

And then, thoughts on the same for measured quantities such as:

AbsoluteDateTime

Duration

(I'll stop here for now)

Dear Doug,

I think this is an important point.

DF> The more that people reuse existing URIs instead of inventing

DF> their own,

the

more utility the massive tuple stores can provide.

MW: One of the things I try to promote is the idea of an authoritative

source,

so not only are there relatively few URIs for the same thing, but

there is

a

natural preference for which one to use. So to cross threads, if we

are looking for what URI to use to identify  Ferrari 458 Italia, the

one

Ferrari

uses should be preferred, because they are clearly the authoritative

source.

MW: This has the corollary that authoritative sources have the

responsibility

to create URIs for the things they are responsible for.

Matthew West
