I was saying that Maps are not there now, and that if they are added, they should be added in a way that preserves the basics of the UIMA idea - supporting interoperability between Java and C++ being one of these ideas. -Marshall > Steve > > >> Anton Shuster wrote: >> >>> Hello all, >>> >>> I tried my best to search for an answer to this topic but came up >>> short.
