In-Depth Information
moderator (e.g. green, yellow, red cards). Articles may be selected (and deselected) as
topics and may be ranked to influence their ordering. An article may have temporal
references (to be displayed on a timeline), keywords (to be searched together with the
title and note), and attributes related to its visibility and accessibility.
Links between articles or sections may be labeled to express relations, such as
refers-to, responds-to, justifies, questions, generalizes, suggests, pro, contra) so that
complex networks (or hyperthreads) can be built. Links between Zeno articles and
sections are visible at both end points and can be traversed in both directions. They
are automatically maintained by Zeno, so moderators may edit, copy and move
groups of articles with their links.
Zeno links may also point to external web resources; they are used for document
references in indigo and for spatial references (to be displayed on a map) in KogiPlan
(

)
.
Users are received on a personal home page. Here they can bookmark and
subscribe sections in order to be notified of their latest contributions. Each section
offers different views: The latest articles, the topics, the complete article structure, a
sorted list of articles as a result of a full-text search, the hierarchy of subsections, or
the timeline. Authors may create or respond to articles in a section, and moderators
may edit, move and copy articles, change links and assign labels, and manipulate
sections. Users and groups are administered through an address book.
Zeno can be assessed from any regular web browser without any local installations.
The Zeno server is implemented on top of open source products: Tomcat as web
server and servlet runner, velocity for templates in the user interface, Java for the
kernel, and MySQL for the data base. Zeno itself is available as open source

Zeno for indiGo
In Zeno, document-centered discourses, or more specifically, discourses about
process models, are made possible through the indiGo integrator and some indigo-
specific adaptations of Zeno.
The structure and ordering of process models and their elements is reflected in the
hierarchies of sections and their ranking. The mapping between these structures is
accomplished through Zeno links, the names of which encode identifiers for the
process model and element.
Moderators first create entries for users and groups in the address book. Next, to
generate a section for discussing a process, the moderators click on the “discussion”
button of the process or any of its elements and then select a group as readers and
writers for the discussion. Subsections for discussing process elements are created on
demand, when users click on the associated processes and selects the discussion
group. The subsections inherit the discourse grammar of their super-section and are
restricted to the selected group as authors.
When a user clicks on an “annotation” button for the first time, a personal section
is created. This section and its subsections can only be accessed by this user with all
rights of a moderator. Subsections for processes and their elements are again created
on demand, when the user clicks on the corresponding “annotation” buttons.
The start page of the indiGo system is automatically generated. The upper part
displays announcements. These are articles in a section called “StartPage” , can be
