From t_pontz at gmx.de Mon Feb 12 04:03:47 2007 From: t_pontz at gmx.de (Tobias Pontz) Date: Mon, 12 Feb 2007 11:03:47 +0100 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?

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.

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.

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.
