File-Like ICN Collections (FLIC)
draft-irtf-icnrg-flic-02
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.
