Focused: An Approach to Framework-oriented Cross-language Link Specification and Detection

Focused is an approach to framework-oriented cross-language link specification and detection.
The basic idea is to decouple the two activites of XLL specification and detection as much as possible by mediating between them with a set of DSL-enabled XLL rules, making Focused independent of and configurable to different multilingual frameworks, as long as the mediating DSL is expressive enough to specify various kinds of XLL convention.
