About

The software "askemos" is an incorruptible and intrusion resistant agent oriented operating system. It forms the basic infrastructure (TCB) required for the project Askemos. The AskemosDesign defines an autonomous, virtual machine on document level, which works synchronous among distributed, independant components (companies, departments etc.).

Big picture

Usually it's not easy to grasp what Askemos is, since it has a few facets. It's importance lies in the combination and seamless integration of a certain set of features found elsewhere too. Nowadays a comparison with couchdb might be helpful.

system overview

This white paper used to be the best one about the design. While it's ageing, it's still a recommented read.

Askemos is expected to be implemented on top of various base systems. (As it's best deployed with one instance at the local host, the next logical step would be to integrate it into the browser. But we are not yet there.) This document describes implementation and administration of the Askemos system available today.

Basics

The current implementation is a two layer operating system built on the foundation of a Unix compatible base system, which does the I/O. The AskemosServer compares to the "exec server" of micro kernel systems.

There are plenty of approaches already, but none was found, which could satisfy the AskemosDesign requirements. Askemos can fulfill those because it overcomes by design a lot of accidental hardness as inherent in legacy systems. Todays operating systems provide abstractions for individual computers, network connections files etc. these have no importance for the developer or user in the Askemos.

Askemos is an environment where simple, collaborating agents may form an intelligent systems. My personal dream of the latter is sort of a public library which can't "burn".

Development at top of Askemos

There are roughly two ways of dynamically generating programm output like websites. One way is the "PHP way" (or Perl, Ruby, pick one). This means you write some HTML code and mix the output from running another program in between. Beeing often used, there are several disadvantages though. For example, operation on fragments of code must all be done on the string-level. Superflous, distracting and potentially buggy code is introduced in your application to parse input and generate output. At worst, your output is simply invalid. Another disadvantage is that malicious or obnoxious HTML and scripts can be inserted relatively easy in the output by any potential attackers of your site, unless you take great care to escape HTML characters - which again clutters you application code.

The other way is to use XML: You use languages like XSL, which includes XSLT and XPath or XQuery?. The BALL kernel blends the latter approach with MIME converters to use simple input syntax like SXML, Wiki or OOo, since reference XML is needlessly verbose and thus hard to write, Scheme and SQL into a system of communicating sequential processes to express your business logic.
