Re: [windup-dev] Namespaces and URLs

Hi Sande, Marek, I know that all are used to -X_Y, but IMO it's a wrong tradition, let me explain why. The rule schema rules location will change with every change of the schema. The older schema needs to stay where it is. The old rules will refer to that schema. We might change our rules, but those rules which are outside our reach will have to refer to a valid schema URL. I remember that in QE dept, these a-b_c-D-e_F.G_h schemas were a source of bugs surprisingly often. Even your examples are inconsistent: http://www.jboss.org/schema/jbossas/jboss-as-logging_2_0.xsd http://www.jboss.org/schema/jbossas/jboss-deployment-structure-1_2.xsd Nobody really can tell why there's a - or _ or . . If we simply use the same version string and only use '-' before it, it's all clear. And, as I said - *the schema only expresses the constraint that is effectively inside of the released implementation*. So it's really *directly related to the particular release*. The fact that we would use 2.3.0.Final for a XSD url or namespace doesn't imply or suggest that it has to change for every release. The string is in 2 places so far, in general: 1) The Windup source, where it should be a single constant in config-xml, referenced form it's dependees. 2) The XML rules, where it can simply stay the same until next review of the rule. Therefore I don't think it would create any maintainance that would not be needed if we use arbitrary version string scheme. The only reason I can see to keep 1_1 is to align with what someone coined up 10 years ago, which for me equals to sticking to a wrong solution. YMMV :) >> I am not really sure if it is good idea to have version in namespace Is there some other way for versioning the schema and the rules?
