Hi Jay, >One of the main things I can't quite envision is how to process the annotations of an external .java file at runtime so that I can utilize that information
You shouldn't have to do this yourself. By using the SciJava plugin framework you get discovery of all annotated plugins on your classpath, and processing/indexing of those plugins, for free. I'm assuming the paradigm that would match your needs is a HandlerService[1]. The service would perform some function (e.g. opening a path) and the behavior of that function would be extensible via HandlerPlugins[2] (e.g. a plugin for handling URLs, files on disk, files in a database, etc...). The simplest example of "service chooses a plugin appropriate for the circumstances" is the AnimalService tutorial[3]. Note that it's not actually a HandlerService but could easily be converted to one. More complex examples would be the IOService[4] or SCIFIO's FormatService[5].
