Subject: RE: Question on use of colons in v3 key names
Tony, Thanks for your feedback. Note that KSS = “Key
Specific String”. It seems to me that colons in the kss SHOULD
be illegal from a semantic and consistency perspective but it COULD be
technically possible because of the way key partitions work (I’m supposed
to be the expert now…!? J ). The UDDI node knows which part of the string is the
key partition and which part is the kss because of the declaration of a
keyGenerator tModel. So “IN THEORY” I could define a key
generator as: Uddi:widgetCo-com:keyGenerator Then create a tModel like: Uddi:widgetCo-com:marketing:niftyService And then, even though there is a colon in
the ‘marketing:niftyService” KSS, the UDDI node knows that it is in
the KSS and not part of a new partition because the original declaration of the
uddi:widgetCo-com:keyGenerator tModel. WidgetCo could, IN THEORY, then go
on to define a new key partition as: Uddi:widgetCo-com:marketing:niftyService:keyGenerator And then define new tModel is that key
generator domain such as : Uddi:widgetCo-com:marketing:niftyService:version1.0 So now we have a tModel key with three
colons but only two of which represent key partitions. Technically
feasible but pretty confusing and pretty bad practice I’d say. So I guess what I am saying is that the
permission or not of colons in the kss is more of a policy issue than a
technical issue because an implementer could manage it without breaking the
model. Is it safe to assume that the TC position is that colons are NOT
allowed in the KSS? If so then we need to review all Technical
notes for the definition of v3 keys that use colons where they shouldn’t
(like the ebxml TN). Comments from the TC welcome… Regards, Steve Capell Red Wahoo Pty Ltd +61 410 437854 From: Rogers, Tony
[mailto:Tony.Rogers@ca.com] I'd say that you have spotted an error. I'm fairly certain that colons are not permitted in the trailing
portion. Indeed, I believe there was a comment on this very subject on the list
in August (late August, I think). The trailing portion is referred to as KSS
(I'm sorry, the definition of that escapes my tired brain at the moment) - you
might want to have a quick look for it. Tony
