Subject: [OASIS Issue Tracker] Commented: (OBIX-1) UML diagram and text needs clarification line 269
[ http://tools.oasis-open.org/issues/browse/OBIX-1?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=34549#action_34549 ]
Markus Jung commented on OBIX-1:
--------------------------------
- For the types maybe the xs: namespace and according XML schema types can be used to define the attribute type
- I will provide an updated XML schema since some other bugs appeared.
- The Val type has currently rather limited purpose. In an object oriented language it could be useful to define an interface that demands a getValue(IObj) and setValue(IObj), but for XML schema it is useless since it shoudl define that all sub types have an val attribute which type is defined by the sub type. I think that's not possible at all with XML schema. So I think it is best either to have a dummy type Val that is just used to mark types as value types or to leave it out completely.

> The UML diagram is generally conformant UML but leaves significant questions for the reader.
> (1) what are the base types? The text suggests but does not state that the underlying types are XML Schema (xsd) types. This should be clarified in the text.
> (2) The UML diagram does not follow the schema; they are not synchronized. The final 1.1 spec must have consistent use of types and implied types in the schemas. See also notes on schemas by others.
> (3) The use of "val" seems odd in UML expression; the apparent metaindication of "<type>" is not standard UML and should be corrected.
