Hi, all Is there somebody can help me? I need to describe a special individual such as one person Tom,whose information includes: ie, Tom Lived in MD in 1980, and T om Lived in NW in 2000. How can I do to relate Person,Somewhere and Date
together? I know Class Person can associate Class Somewhere with Object Properties Lived in，but how to do about the Date which looks like a restriction. Thanks! Best,james

So in this case you will have to create more than one individual per
city, isn?t it?
Let's assume Tom lived in NY in 1990 and Kim lived in NY in 1995, you
will have to create one individual NY for 1990 and one individual NY
for 1995 no?
Is there any other way to represent that?
Maybe you can have a class person, a class period (with a datatype
property for the beginning and another one for the ending year) and a
class city.
The person has an ObjectProperty with range period and the period has
an ObjectProperty with range city.
In this case you will have one individual per city...but possibly more
than one per period.

You can find some approaches to representing time in OWL in [1, 2].

Thank you! Those approaches seem to be useful to me. 2009/12/3 Martin O'Connor <[hidden email]>

Hello there,
You can include a date as a Datatype property in your Somewhere
class and
you can have more than one Person --> Somewhere relations for the same
Person.

Yes, it is. I guess it is not good idea. It makes the case model be unclear. Thank you1 2009/12/3 Cedric Peeters <[hidden email]>

Since OWL only has binary properties, you will need to end up creating
a reified relationship in order to attach the additional information
about the residence.
So, for example, you would have
Tom hasResidence residence-001
Tom hasResidence residence-003
residence-001 hasLocation MD
residence-001 hasStartDate 1980
residence-003 hasLocation NW
residence-001 hasStartDate 2000
etc.
The names residence-001, residence-003 can either be automatically
generated, or you could look into using anonymous individuals.

If you are using OWL 2 you can use annotations on Axioms, in this
case, for example, having the date be an annotation on the x
has_location y axiom.
