-Semi-automatic garbage collection is a hybrid approach which relies on an underlying local GC and proposes a non-transparent DGC. The approach can be seen as an extension to the indirect reference counting (Piquer,1991) and network objects (Birrell et al.m 1993) since it also maintains the distributed inverse reference graph (IRG) where each remote object keeps a list of pointers to other devices which have references to it. The IRG is augmented with additional semantic information attached to the remote references to help the collector to determine the reachability of the remote objects they point to.  This means the developer will be able to steer the gc proccess and accomodate the requirement of the applications by means of annotating the remote references. +Semi-automatic garbage collection is a hybrid approach which relies on an underlying local GC and proposes a non-transparent DGC.

 We are currently exploring the necessary referencing strategies for the developer to annotate remote references. We have come up with a tentative classification of referencing strategies that can be found [ [[http://prog.vub.ac.be/Publications/2006/vub-prog-tr-06-16.pdf| here]] ], but we are still investigating the semantics of these constructs.   We are currently exploring the necessary referencing strategies for the developer to annotate remote references.
