The CAS doesn't natively support hash maps. One possible motivation is that the design was aimed at allowing multiple independent systems to process the CAS data, including Annotators written in C++. To support this, it would be necessary to implement a common hash map in multiple languages (Java, C++, Python, Perl, etc.), which wasn't done.
Richard's suggestion is a possibility, though. The other thing that people sometimes do is to store map data in external resources, which can be shared among co-located Annotators (running in the same JVM). -Marshall On 10/16/2013 11:55 AM, Dr. Armin Wegner wrote: > Hi, > > I'd like to have a type feature that is a list of key-value pairs.
