Inconsistencies in the WS-Agreement Specification (GFD.107) and WS-Agreement Schema (ws-agreement.xsd)
by Knud Mikkat 07 May '10

07 May '10

Dear Ladies and Gentlemen, I'm currently workin on an OWL based ontology for Service Level Agreements based on WS-Agreement for my bachelor thesis at Karlsruhe Institut of Technology (KIT). Studying the standard you provided as well as the XML schema, I faced some (imo) inconsistencies. In the written part of your standard, you do do repeatedly define terms comprising *one or more* service terms (cardinality 1..*) and *zero or more* guarantee terms (cardinality 0..*)" (page 4, page 14). Therefore I interprete that a single GuaranteeTerm without any ServiceDescriptionTerm / ServiceReference / ServiceProperty ain't intended to be possible. Whatever, the coding integrated in the standard document (page 17/18) as well as your provided ws-agreement.xsd allow terms comprising ONLY a single GuaranteeTerm. Another point is that in the textual description, you engage ServiceTerm as super class of ServiceDescriptionTerm, ServiceReference and ServiceProperty while the entity ServiceTerm ain't used in you example coding (page 17/18) nor in the provided XSD. My question is now whether the GFD provided implementation (no ServiceTerm class, single GuaranteeTerm possible) or the standards' text shall be referenced to for futur work. Attached you can find some pseudocode to underline my thoughts. Best regards, Knud Mikkat -- Knud MIKKAT Student der Informationswirtschaft (B.Sc.)
