Internal Occurrences (4)
-
Description
- According to XTM 1.0 the default occurrence type is the
"occurrence" published subject. Should this standard follow its lead?
If so, what does it mean?
-
Opinion
- ISO 13250 does not recognize the
"occurrence" default type introduced for XTM. If this is imposed on
the standard, then a means of clearly distinguishing default types
from user-defined types needs to be added to the model so that imposed
subjects specific to the management of the model can be distinguished
from the subjects that the author specified as part of the Topic
Map.
- Scope: Martin Bryan
- Occurrences with no type should
have an undefined relationship instead. What practical purpose does
this default type serve?
- Scope: Geir Ove Grønmo
-
Resolution
- This default type is not
considered to be of any practical utility, and it is therefore not
retained in the SAM. Applications that wish to use these published
subjects may still do so.
