New (revised) version of the DAML-S 0.9 Profile


Sorry to have taken so long in these revisions.  Change Log:


*	File name changes have been made (as requested) by David
*	Have removed all reference to the class Actor within the

The Actor class (and its properties) are now in ActorDefault.daml.  This

also contains the additional fact about profile#contactInformation


  <daml:ObjectProperty rdf:about="&profile;#contactInformation">

    <daml:range rdf:resource="#Actor"/>



Thus, if the ActorDefault ontology is appended to the profile ontology
(i.e. if both files

are loaded into some reasoning engine), then the behaviour should be
exactly the same

as if the separation of Profile and Actor hadn't been made.


If other classes are preferred, then the above extension should be used
to define the new range.

For example, if the Friend-of-a-Friend person concept is used, then the
following statement should

be included in a profile instance, or included from another file:


  <daml:ObjectProperty rdf:about="&profile;#contactInformation">

    <daml:range rdf:resource="http://xmlns.com/foaf/0.1/Person"/>



*	Combined updates with existing profile updates:

*	Changed definition of entity xsd to 

<!ENTITY xsd "http://www.w3.org/2001/XMLSchema">

*	Modified the entry for Dun and Bradstreet Rating to refer to a
string, not an integer 



One confusion, David, you mentioned that you had changed uriReference to
anyURI but I couldn't find any reference to either of these entities in


David, if you are happy with these changes, could you update the entries
in the release?  I will provide updated ontology diagrams shortly.

Terry - 

Thanks for taking the lead on these changes.  I agree these are
substantial improvements, and it's fine with me to get them into 0.9. 

I'd still like to get more clear about the motivation for the
serviceParameter property; perhaps we can discuss this tomorrow.  But
that probably doesn't affect your proposed changes, so let's go ahead
and move forward with your changes. 

My only comments are regarding file names.  We sort of have a naming
convention.  That is, both for identifiers and for filenames, I've been
avoiding hyphens and underscores and relying on capitalization.  So, how
would you feel about these: 




Cheers, David

I'm soliciting comments on the following proposed changes to the DAML-S
Proposal (V0.9).

I've taken a look at the Profile, and have made some recommended
changes.  Significantly, I've pruned down the Profile (based on various
comments made from discussions at the DAML-PI meeting, the SWSI meeting
and tonights telecom) and moved some concepts to additional files. 

1) Profile-additionalParameters.daml 

I've removed the example profile classes (listed below) and placed them
in their own file. 

I'm not wedded to the name (Profile-additionalParameters.daml) so if
people want this changing, that is fine.  We should still offer these
class definitions, both as examples of how parts of the profile ontology
can be used, such as serviceParameters, and serviceCategories, and as
useful concepts in their own right.  However, as these do not define the
core ontology (rather, they support it), they have been abstracted. 







2) Profile-Depreciated-elements.daml 

I've removed the deprecated properties (from 0.7) and just put them in a

I haven't gone through this file to ensure validity; in fact we might
want to turn this file into a document, as it serves more as a reference
doc (listing deprecated functions and their meaning) and shouldn't be
redefined in a new namespace.  Remember that we are not removing the
erlier ontology versions, so these properties 

3) Actor-defaultProperties.daml 

I've moved the properties of the Actor class into their own file.  At
the ISWC F2F I was asked why we defined our own Actor class when there
are several other "person" type classes.  This is a good question!!! 

So by moving the properties to a separate file, we only define the class
"Actor" in the Profile as a subclass of thing, and say no more about it.
If people wish to use the original Actor properties, then this can be
achieved simply by including Actor-defaultProperties.daml, which extends
the "Actor" class with the additional properties.  From a reasoner's
perspective, this situation would be no different from that of 0.7.
However, if one chooses to use another ontology (e.f. FOAF or vCard, or
define their own), then the mapping can be achieved by defining a
sameClassAs relationship between the Actor class and the new class. 

There may be other implications of this, e.g. different definitions of
Actor in different profiles which then are registered in the same
Matchmaker, so feedback would be appreciated.  But I suspect that these
implications could occur anyway, and may be more problematic if we
assert the Actor properties in the Profile ontology. 

4) Profile.daml 

There are a couple of small cosmetic changes, such as changing any
remaining rdfs constructs to daml constructs, updating the change log,

If people are happy with the suggestions, then I suggest we migrate the
new files to the release site and I will provide additional
documentation describing the changes, as well as examples that
illustrate how the Actor usage can be modified.  Additionally, small
changes may be needed with our 0.9 examples.  Again, I'll assume
responsibility for this.
