Subject: RE: [wsrp-wsia] Roles
J2EE also has the concept of role mapping in that a developer can write her application in terms of her usual set of roles. The deployer of the application can then map those roles, at deployment time, using a relatively simple XML role reference description mechanism. I view wsrp consumer roles as the analogue of the J2EE developer's role set, the consumer Portal admin as the analogue of the application deployer (at service registration time), and the role names on the wire as the J2EE container roles. So, we potentially have two similar mappings of roles: consumer to producer and JSR 168 Portlet to J2EE Container? Each requiring human intervention. regards, Andre -----Original Message----- From: Rich Thompson [mailto:richt2@us.ibm.com] Sent: 26 November 2002 12:52 To: Martin Bryan Cc: wsrp-wsia@lists.oasis-open.org Subject: Re: [wsrp-wsia] Roles I have had the uneasy feeling about roles for a while, but rewriting those sections finally caused me to focus on it enough to see the detailed reasons why (you site some good examples). At this point I think it is only useful to that set of Consumer-Producer pairs that have a coordinated set of roles and since we won't be able to define tight semantics it doesn't belong in the spec. On the address side, the variations in address are a big issue and WSRP is not the right place to tackle it. We took guidance from the P3P data model in this area though we did need to provide some structure for their unstructured portions. I was hoping much of the variability could go into the field named street as this is an array of strings. In addition, each of the structures is individually extensible with the expectation that some of those extensions will come back for consideration as base level fields in v2. If there are other sources that would give a more internationalized view of this area, we certainly would appreciate a pointer ....

Now consider what happens if the Producer is Finnish and the Consumer is Japanese and both use their own languages to define their services. Now we have a real problem, which will only be solved if you introduce a multilingual ontology of mapped terms into the equation. The real problem, however, is how to do this dynamically, so that we can annotate recorded roles with "related names from other sources" (e.g. record that someone has determined, by some off-line means, that A relates to B). Incidentally your address info structure in section 10 has not been suitably internationalized. You need techniques for defining subsections of what you call cities (e.g. Kensington, London) and for identifying blocks (both at street and house level) and subunits of buildings (flats or suites). For example, I have a friend in Roumania for whose address I need to identify the flat number, the staircase, the block on the road (unless you call Block 26 a name!) and the district of the town in addition to the fields you allow me to define once only if I want to send him something. It looks like I'm going to have to define more extensions than you do base fields, even though every different Consume and Producer will have to define his own set of extensions for most of these :-( Martin Bryan The SGML Centre, 29 Oldbury Orchard, Churchdown, Glos GL3 2PU, UK Phone/Fax: +44 1452 714029 E-mail: mtbryan@sgml.u-net.com For further details about The SGML Centre visit http://www.sgml.u-net.com ---------------------------------------------------------------- To subscribe or unsubscribe from this elist use the subscription manager: <http://lists.oasis-open.org/ob/adm.pl>
