File-Like ICN Collection (FLIC)
draft-irtf-icnrg-flic-00
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.
