afslib is a library for reading Archival File Systems (AFS). The AFS has unique preservation capabilites, including support for human readable data, file format ids and other types of metadata. A design goal for AFS is to provide a completely self contained file system, containing all information needed to decede and understand its content in the near and distant future. The AFS file system is primarily intended for linear tape storeage mediums.
The key components in the AFS is the zero-reference-mark indicating the start of the file system, the control-frame containing information about how to decode the rest of the reel and the table-of-content pointing to all files stored on the reel. The file system is organised into sectors, called frames, where a frame occupies a rectangle on the storage medium surface. The frame can contain either visual or digital data. The data on the frame could be encoded using any kind of 2D barcode format. Current instances of AFS uses the boxinglib 2D barcode format.

- Simple file system with unique preservation capabilities
- Portable
- TOC supports both digital and visual data
- TOC supports file metadata in any format
- TOC supports file format identification
- Control frame supports self contained bootstrap for decoding rest of the reel
C language compiler supporting C99 (ISO/IEC 9899:1999).
A design goal is to have as few dependencies as possible.

The iVM virtual machine is a minimal execution environment for file format decoders. It's design goal is to minimize future implementation effort by providing an unabmbigious and compact implementation description.
The afs library is one of the formats the iVM natively supports.
To target the iVM and use the ivm64 compiler:
CC=ivm64-gcc ./configure --host=ivm64 LIBBOXING_DIR=<absolute path to boxinglib>
