Simple Web-Accessible Storage
SWAP, the Simple Web-Accessible Preservation system.


=Overview=
SWAP is a web-based distributed storage system for managing multiple collections. It interleaves data across many storage partitions on different nodes while providing a consistent namespace. Clients place and retrieve data using basic http operations. Even though data is distributed, clients may access any stored data through any swap node. It has also been designed to be completely disposable, allowing for data recovery in case the SWAP software is completely removed.


SWAP provides a simple mechanism to distribute data across multiple partitions or servers while providing simple mechanism to retrieve all data.


Below is a set of key design goals for SWAP:

# Data must be easily accessible in the absence of ANY software beyond basic directory access.

# No centralized metadata server.

# Provide http access to data.

SWAP, the Simple Web-Accessible Preservation system.

SWAP is a web-based distributed storage system for managing multiple collections. It interleaves data across many storage partitions on different nodes while providing a consistent namespace. Clients place and retrieve data using basic http operations. Even though data is distributed, clients may access any stored data through any swap node. It has also been designed to be completely disposable, allowing for data recovery in case the SWAP software is completely removed.
