Subject: [GRAAP-WG] Evaluation of Service Level Specifications
Message-ID: <000001c74e8d$1a5546a0$0300a8c0@obelix>
Hello all,
I'm writing my diploma thesis at the moment in comparing different Service
Level Specifications (like WS-Agreement, WSLA, MNM Service Modell, WSMN,
WSOL, ...). I decided to create a catalogue of requirements. Here is the
structure:
- abstract requirements
- searching and finding
- specification language
- SLA-negotiation
- modelling SL parameter
- measuring and monitoring
Now I'm looking for some criteria for every named point (e.g.
searching/finding: centralized/decentralized directory; modelling:
bottom-up/top-down). What do you think are important criteria? Did I forget
something? Did I forget an important specification? Do you know about
comparable workings?
Thanks
Tobias

Subject: [GRAAP-WG] SLA Template
Message-ID: <45D04777.1010408@battre.de>
Hello everybody,
for the AssessGrid project, we are working on SLA support for our
resource management system.
At the very moment, I am in the stage of generating an extensive SLA
template to get a good feeling about the current WSAG specification. (I
didn't follow the development for some time because I was busy with
other projects).
I would like to send you my results for comment once they are available,
but right now I have encountered the first problem already. Maybe you
can help me with this:
I would like to add a CreationConstraint that models a boolean flag,
whether some fault tolerance mechanisms need to be activated.
The respective XML fragment looks like this:
//assessgrid:FTService/assessgrid:Requested
So what do I put there to allow only true and false?
My first idea was to use a xs:restriction like
but to my surprise my editor (WTP of Eclipse) tells me that
xs:restriction is not a valid tag at this place - despite being
explicitly mentioned in the WSAG specification. Now, who is right? The
syntax checker of the editor or the WSAG spec, or both, meaning that I
am wrong?
The error message is:
cvc-complex-type.2.4.a: Invalid content was found starting with element
'xs:restriction'. One of
'{"http://www.w3.org/2001/XMLSchema":simpleType,
"http://www.w3.org/2001/XMLSchema":minExclusive,
"http://www.w3.org/2001/XMLSchema":minInclusive,
"http://www.w3.org/2001/XMLSchema":maxExclusive,
"http://www.w3.org/2001/XMLSchema":maxInclusive,
"http://www.w3.org/2001/XMLSchema":totalDigits,
"http://www.w3.org/2001/XMLSchema":fractionDigits,
"http://www.w3.org/2001/XMLSchema":length,
"http://www.w3.org/2001/XMLSchema":minLength,
"http://www.w3.org/2001/XMLSchema":maxLength,
"http://www.w3.org/2001/XMLSchema":enumeration,
"http://www.w3.org/2001/XMLSchema":whiteSpace,
"http://www.w3.org/2001/XMLSchema":pattern,
"http://www.w3.org/2001/XMLSchema":group,
"http://www.w3.org/2001/XMLSchema":all,
"http://www.w3.org/2001/XMLSchema":choice,
"http://www.w3.org/2001/XMLSchema":sequence}' is expected.
This matches mostly with the specification except for the xs:restriction.
Coming back to the problem of modeling "Put true or false there", what
would be the best way? If I understand the xs:group, xs:all, xs:choice,
xs:sequence correctly, they all operate on complex types. Does this
leave anything but the xs:pattern alternative? (Note that true/false is
just a special case for any kind of enumeration.)
Thanks,
Dominic
P.S. In case you have some example files of templates, I would be very
interested in having a look at them.

Jim,
I can't make the call today, sorry.
However, I would very much appreciate a note afterwards
on when to expect the WS-Agreement spec to be re-submitted
to the editor. I think the group is really close, needing
only the tiniest push to get there.

The minutes do not really make clear when the document will be submitted
to the editor. Is there some clearness what needs to be done and
when this will be ready?

Hi Dominic,
since you are using our implementation I think the following code should
work for you:
AgreementTemplateType template =
AgreementTemplateType.Factory.newInstance();
template.setAgreementId("some_id");
AgreementContextType context = template.addNewContext();
context.setServiceProvider(AgreementRoleType.AGREEMENT_RESPONDER);
template.addNewTerms();
ConstraintSectionType section =
template.addNewCreationConstraints();
OfferItemType offer = section.addNewItem();
offer.setLocation("some_location");
ItemConstraint constraint = offer.addNewItemConstraint();
LocalSimpleType simpleType = constraint.addNewSimpleType();
Restriction restriction = simpleType.addNewRestriction();
restriction.setBase(new QName("http://www.w3.org/2001/XMLSchema",
"string"));
restriction.addNewEnumeration().addNewValue().setStringValue("true");
restriction.addNewEnumeration().addNewValue().setStringValue("false");
This creates the following XML:
AgreementResponder
some_location
I think this is what you want.
Regards,
Oliver

Dear All,
I will not make it to the call, but I want to report a few things:
- I started updating the living charter on the GridForge page. Once it
is ready, I will send it around for comments.
- I cleaned up the Document repository a bit, putting all the outdated
stuff into a seperate folder. This should make it easier for people to
find what they look for.
- I plan to use the Wiki for presenting information to people intersted
in GRAAP. We may put links to implementations, presentations, papers,
etc. there.
Best regards, Philipp.
