[Haskell] ANNOUNCE: Holumbus-MapReduce 0.0.1

[Stefan Schmidt]

The Holumbus framework is known for building specialized search-engines 
like the Hayoo! Haskell API search. Now, I'd like to announce the newest 
libraries of the Holumbus framework:

Holumbus-MapReduce    0.0.1
Holumbus-Distribution 0.0.1
Holumbus-Storage      0.0.1

As part of my Master's Thesis at the University of Applied Sciences in 
Wedel, Germany, I have developed a library for building distributed 
MapReduce systems in Haskell. The existing Holumbus-Searchengine library 
already offers a MapReduce implementation, but it does not provide 
mechanisms for distributed computing. The newly developed 
Holumbus-MapReduce library contains of tools and modules for building 
individualized distributed MapReduce systems.

Holumbus-MapReduce is based on two libraries: Holumbus-Distributed and
Holumbus-Storage. Maybe they could be useful for building other 
distributed systems, not only a MapReduce system.

Holumbus-Distribution consists of modules and tools for the 
implementation of distributed systems in general. Besides common data 
types and small helper functions, this library provides a mailbox-based 
data transfer mechanism. It offers an easy-to-use interface for inter- 
and intra-process communication like in Erlang or Mozart/Oz.

Holumbus-Storage is designed to build a distributed storage system which 
can be linked into other programs. It is used by the MapReduce system 
for the data management.

All three libraries are still under heavy development and should not be
considered for creating applications in productive environments. But I 
think, it's time to give them to the community for suggestions on 
further development and features.

Please email comments, bugs, etc. to sts at holumbus.org
