We just released our concept browser Conzilla in version 2.1 together with our collaboration server Collaborilla 1.0. Both applications are open source and have been licensed under the GPL.

The biggest changes from the last version (2.0) are:

• Support for collaborative conceptual modeling (publication of and contribution to context-maps), supported by the collaboration server Collaborilla.
• Support for Dialogue Mapping.
• Java Web Start support for easy installation and maintenance.
• Refurbished user interface and usability improvements.
• Export of context-maps to the formats SVG, PNG and JPEG.
• Bookmarking functionality.
• Improved layer management.
• Color theme support.

Conzilla 2.1 requires a Java Runtime Environment in version 1.4.2 or newer.

Our paper “Collaborative Construction of Artifacts” got accepted at the 4th Conference on Professional Knowledge Management “Experiences and Visions”. We are going to present it at the Workshop for Collaborative Knowledge Management (CoKM2007).

Eventually the SHAME web is restructured as a wiki. Additionally:

• It has also gone through an overhaul with respect to terminology.
• There is a new logo
• The velocity demo, named Speed, has been improved (global state replaced with sessions).

Finally Conzilla2.0 is released, named Lime after the new Lime-ish background color.

After wrestling with slapd (the OpenLDAP daemon) for a while I finally created a custom schema with an own ObjectClass and attribute definitions. I will shortly describe the possible fields and how they are supposed to work together.

After digging deeper into the topic LDAP I discovered that it was not really designed to keep several versions of a single node. To make this possible anyway I decided about a special structure.

LDAP is the most reasonable storage technology for the resolver and referrer service. Standarized ObjectClasses, small overhead and fast read access to entries. Updates will not occur in a dimension that would make a fast RDBMS necessary, so we do not care much about the writing speed of LDAP.
