Subject [jira] Commented: (UIMA-1290) Need a Way to Determine if Two Type Systems Are Compatible
Date Tue, 10 Feb 2009 14:41:06 GMT

    [ https://issues.apache.org/jira/browse/UIMA-1290?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12672277#action_12672277

Thilo Goetz commented on UIMA-1290:

Not sure I understand all the requirements.  When you say "type system", do you mean a type
system object like in CAS.getTypeSystem(), or do you mean an XML rendering?  I understand
that for binary serialization, the type systems must be identical in the sense that the internal
type codes must be the same.  What do you mean by "compatible"?  And what do you mean by "validation
of type systems"?

> Uima AS client needs to validate that the type system returned from a Uima AS service
is compatible. In case when a binary serialization is used, the type systems *must* be identical.
For XMI serialization, the type system of the delegate*must* be compatible but not necessarily
identical. The core should provide an API which will enable the validation of type systems.
