Another possibility are external resources. When defining external
resources one or more annotators can share the same resource.
The UIMA framework take care of the resource's life cycle.
You will find some documentation about external resources in the UIMA
reference guide at 2.4.1.10. External Resource Dependencies.
You can also check the UIMA examples - tutorial ex6 use external
resources. (apache-uima/examples/descriptors/tutorial/ex6)

persisting the info that way, not sure if this is
a requirement or not.

What is the best practice for sharing read/write resources amongst
analysis engines in an aggregate? For example, say you have an annotator
early in a flow that reads a configuration file off disk in order
determine its behavior. Then, the next annotator does something, and
needs to write changes to the configuration file so that another
annotator downstream, whose behavior is also determined by the contents
of the configuration file, can read in the resource that contains the
changes.
Does this make sense?
Any help or ideas would be appreciated. I can think of some ugly hacks,
but it would be nice to know if I'm missing some portion of the API that
supports this type of scenario.
Thanks, Andrew
