Abstract

   This document describes a bare bones "index table"-approach for
   organizing a set of ICN data objects into a large, File-Like ICN
   Collection (FLIC).  At the core of this collection is a so called
   manifest which acts as the collection's root node.  The manifest
   contains an index table with pointers, each pointer being a hash
   value pointing to either a final data block or another index table
   node.
