Comments WS-AG Spec
by Dominic Battre 23 Jun '05

23 Jun '05

Hi. I haven't followed the mailing list very closely recently, so I read the current specification again after a long absence. I don't know, whether you are still looking for comments, but these are some points, that came into my mind. Some typos and inconsistencies and some requests for possible clarification. Have a good travel to Chicago. Section 1.3 Namespace The prefix should be xsi instead of Xsi (lower case x) Section 4.1 Agreement Context most objects are optional, so I think the gray box should have several ? instead of + to indicate that. it should be /wsag:Context/{any} and /wsag:Context/@{anyAttribute} instead of /wsp:Context/... Section 4.2.1 Term Types: <wsag:Term Name="xsd:NCName?"/> -> <wsag:Term Name="xsd:NCName"?/> (moved ?) Section 4.2.5.1 Variable Set wsag:Metric="xsd:QName"? in gray box (new ?) as "This element is optional and..." Section 4.2.6.3.3 Preference I am a little bit confused about the /wsag:Preference/wsag:ServiceTermReference: what does it reference? /wsag:ServiceDescriptionTerm@wsag:Name? in that case, the type should be xs:NCName How come, you don't use wsag:Location? "/wsag:Preference/wsag:Utility This element can appear multiple times, one corresponding to each ServiceTermReference." Where is the connection of Utility to the ServiceTermReference? First S.T.R. <> first utility, second S.T.R. <> second utility, ...? I have read the schema files and from that I think it is better to put <wsag:Preference> { <wsag:ServiceTermReference>xsd:string</wsag:ServiceTermReference> <wsag:Utility>xsd:float</wsag:Utility> } + </wsag:Preference> into the gray box. Section 6 Compliance of Offers with Templates "In order for an agreement offer to be accepted, it MUST comply with at least one template advertised by the agreement provider to which the offer is submitted." In section 4.1 Agreement Context, you have requested that the /wsag:Context/wsag:TemplateName points to exactly one agreement template. I think it would help to add statements whether it is allowed to - add Terms that are not specified in the AgreementTemplate's Terms section, - delete Terms from the Agreement, that are part of the AgreementTemplate's Terms section but are not referenced in its creation constraints. As the added or deleted terms are not expressed in the wsag:CreationConstraints section in these cases, I assume that both operations are valid. Section 7.2 Guarantee States The guarantee states describe the current situation, but what is the semantic of the current situation? Example "I request a response time of <1 sec.", this response time has been exceeded for 1 hour yesterday, but we are within the limits again. Is the guarantee to *always* offer response times <1 sec fulfilled or not? Appendix Template <wsag:Item wsag:name="argumentsTerm"> <wsag:Location>//wsag:ServiceDescriptionTerm/job:arguments</wsag:Location>  </wsag:Item> is "allowed" the right wording? From how I interpret the WSAG specification, it is required. Best, Dominic

minutes from 6/7 teleconference
by Jim Pruyne 22 Jun '05

22 Jun '05

They are attached. Next meeting will be on 6/16 at the usual time of day and phone numbers. --- Jim Minutes from June 7 '05 Telecon Attendees --------- Jim Pruyne Asit Dan Toshiyuki Nakata Heiko Ludwig Philip Wieder Agenda ------ - GGF Sessions: Three are requested. Spec. work, Implementations, and future looking. Implementations will have about 15mins. each, and we'll end with about 30-mins of discussion leading to ideas about how interop. will proceed. **Action: Jim to send out requested set of points to be covered in the implementations presentations. - OGSA Roadmap document: Will include section on ws-agreement as a "crucial" spec. to ogsa. Jim sent feedback on this to encourage vision beyond just job management. Toshi discussed with Hiro, chair of OGSA-WG, and idea is that ws-agreement fits more into the "EMS" section of ogsa rather than the "BES" as BES is more simplistic and simply a "container." **Action: Jim to circulate the roadmap document to the graap mailing list. Philip involved with some of the EMS related work such as "RSS." There will be an RSS BoF at GGF. Philip can act as liason to some of the work in OGSA in this area. - Status of needed updates: **Action: Heiko will act as integration point over the next week, and send status of updates to Toshi to update his spreadsheet. Item 1: Toshi Item 3: Related Agreement removal: Heiko Item 4: Heiko Item 5: Toshi Item 8: Heiko Item 9: Same as 3 Item 10: Toshi Item 11: Heiko Item 16, 17: Heiko Item 18: Handled as part as number 5 Item 19: Heiko Item 20: Jim; make it like WSDM with a terminology section at the beginning Item 21: Asit Item 22: Need to discuss on June 16 Item 24: Jim to contact Tiziana again about this. Item 26: Toshi will lok into this with Karl Item 27: Heiko Item 29: Extensibility of term types; Heiko Items 31-36: All fall into guarantee term updates; Heiko Others: Item 3: Toshi Item 4: Related to 26 Item 5: Asit to provide some text to Toshi Example updates: Asit WSDL updates and passing through XML validators: Heiko and Jim to address when other changes are complete

Service provider id has been added to the context. This sounds good since if it were in terms it could not be filled in by the provider when an offer agreement is accepted since the terms cannot be updated upon acceptance. Item 9: Same as 3--complete Item 10: Toshi--complete, used "evolving instutitional" as in OGSA roadmap. Item 11: Heiko-- complete Item 16, 17: Heiko--Complete accept for section refs.

Item 19: Heiko-- complete Item 20: Jim; make it like WSDM with a terminology section at the beginning--To be done Item 21: Asit--complete, but need review of schema work in 9.5.1 and 9.5.2.-- perhaps change to xsd:any##other Item 22: Need to discuss on June 16-- Defer to next call or GGF discussion Item 24: Jim to contact Tiziana again about this. Item 26: Toshi will look into this with Karl--Should be post-1.0 of WS-Agreement since faults in WSDL and language mappings are not good. This item itself is complete. Item 27: Heiko--complete Item 29: Extensibility of term types; Heiko--complete but check with Heiko Items 31-36: All fall into guarantee term updates; Heiko Others: Item 3: Toshi Item 4: Related to 26 Item 5: Asit to provide some text to Toshi--nothing from Asit yet. **Action: Asit to send. **Action: Jim to clean-up WG members/acknowledgement/author list.

Re: [graap-wg] WS-Agreement spec
by Toshiyuki Nakata 06 Jun '05

Hi: Rather than fighting with MS-Word, I decided that adding entries in the Excel sheet to mark what is reflected and what is not reflected in the spec would be quicker and gives the whole scope better.. So I added two columns in Public Comments. I hope they make the situation more clearer.. Best Regards PS in Page 15 there are two '/wsp:context' should these be '/wsag:context'??

Request for WS-Agreement Implementation experience and plans
by Jim Pruyne 02 Jun '05

02 Jun '05

All, At GGF14, we'd like to host a session on people's experience implementing and plans for using WS-Agreement. To do this, we need participation from those who have this experience. So, I'm requesting that anyone who's implemented all or parts of WS-Agreement take part in this session. Also, anyone who is evaluating WS-Agreement for a specific purpose is welcome to present. The goal is to expose this experience to all, and ideally capture shared understanding of what's worked, what hasn't, and what issues we see when considering interoperable WS-Agreement implementations. We'd also like to find out what common scenarios or use cases we can derive which will help with further discussion in the future. Anyone who can contribute, please let me, and preferablly the entire mailing list know by replying to this, and I'd like to talk with you further about participating in this session at GGF. Thanks! --- Jim
