Hi everybody,

I'm currently developing the Info Service Ontology [1,2,3,4], which enables an association of arbitrary resources to its underlying information service (see [5] for a definition of the term 'information service'). Furthermore, such an information service could then be described, categorized and rated (re. its information service quality) through the is:InfoService concept[2] and its relations to more detailed description concepts (see [3] for a proof-of-concept example). As it becomes more and more important for data/knowledge consumer to (maybe automatically) select the right/a good information service, which delivers this information, an information service quality rating could probably deliver information, which will hopefully help the data/knowledge consumer to find a good choice. These information service quality ratings could be done by several information service quality rating agencies for different information services (also based on maybe different Info Service Quality Ontology specifications, e.g. [7] as an interesting information quality classification).

Now to the important part, why I'm contacting your list ;)

How do you think about the relation of sioc:Space ("A Space is a place where data resides, e.g. on a website, desktop, fileshare, etc. ") to is:InfoService ("An Information Service is this part of an Information System that serves data/knowledge/information to customers and collects it from its contributors, to manage and store it by optionally using administrators."). I figured out sioc:Space as the most equal concept to is:InfoService. However, I still think that the definition of sioc:Space maybe concentrates on the 'online' domain, where on the other side, the definition of is:InfoService should capture both domains - the 'online' and 'offline' domain.

As already mentioned on the Info Service Ontology mailing list[6], there are (more or less, so far as I know) three ways for defining the association/relation between the concepts sioc:Space and is:InfoService:

1. :my_instance_of_something a sioc:Space , is:InfoService . # the association is then only on the A-Box level

2. sioc:Space owl:equivalentClass is:InfoService . # this is maybe the most strongest relation

3. sioc:Space rdfs:subClassOf is:InfoService . # this expresses a bit stronger that sioc:Space is a part of is:InfoService

How do you think about building this relation?

In general, it might be enough to define a 'best practice' re. suggesting association case '1.' for typing instances with a is:InfoService association. However, I think building a stronger relation might be better for reasoning options (following the principle: tell the (dumb) machine as many as you know) and also a bit easier in defining individuals.

So, please let me know, how you would create this ontology concept relation.
Thank you for all your (forthcoming) efforts.

Cheers,


Bob
