Participants◦ Have different time schedules◦ Live in different time zones

Meeting Organizer (convener)◦ Need to keep track of participants replies◦ Decide the best time for a meeting

Business◦ Some participants attendance are mandatory◦ Minimum percentage of attendees have to be met

Problem


This project applies rule-based technologies to

improve the face-to-face and virtual meetings scheduling process with participants who can be geographically distributed with busy schedules

Add more rules to the existing set of rules that are time and business driven

Provide intelligent feed back to Meeting organizer in the case a meeting can’t be scheduled

Provide real time manipulating capabilities to the meeting organizer for changing the meeting constraints:

Minimum attendance percentage Attendance of all mandatory participants


The project team will design and build the RoboComm system for a web-based platform using the following open source development tools:

ZIMBRA◦ Supports e-mail, calendar and search facilities.◦ UI using AJAXToolKit

100% Javascript UI Based on Model View Controller (MVC)

JRules 4.0 for rule-based inferencing


Implementation Constraints

Pops-out a new dialog box for creating a calendar

Unchecks previous calendars and only selects the new

calendar

A new appointment is directly created without

showing a dialog box having meeting name as subject

A meeting can not be created by selecting two

calendars at a time. This condition is notified by giving

an error message


Create a new “Reply Option” menu button and place it on the tool bar

Create a new view (ZmCalReplyViewMenu.js) for the “Reply Option”

Redirect to the reply form “Meeting.jsp” which contains meeting requests


Fixed a problem while dragging an appointment (changing the time)

A new option on right click on an appointment to suggest new timings.

The view of “New Meeting Proposal” is a duplicate of “Week View”


Other UI changes

Firebug: ◦ Javascript debugging on the Client Side

JPDA (Java Platform Debugger Architecture)◦ Remote (Server Side) Java debugging◦ Debugs JSP/servlets with breakpoints


Learnt about Zimbra, JBoss and how they work.

Learnt the MVC architecture for software design

Challenges Difficulty in modifying an implementation by

others.

No code documentation for Zimbra



Describe the operations, definitions and constraints that apply to achieve some desired goal

This is a software system that helps manage and fire the rules


Rules and Rules Engine


Rules Engine Architecture

(these are bootstrap rules)

1) Weekday and weekend for a particular meeting based rule 2) Office hours for meeting time based rule


(when invitees send back reply)

3) Possibility of a meeting time by calculating threshold based rule

4) Mandatory and optional members for all meeting based rule


Team work

Time management

Knowledge of JBoss rules and its importance

Working on Zimbra, Javascript


Rules were developed independently from the web interface

Also, dynamically firing the rules after changing the facts will result in dynamic output


Integration of JBoss Rules with Web Interface


Meeting Tool Form


Data Used for Meeting Tool Analysis All data about a particular meeting is

captured to analyze the possibility of a meeting in accordance to meeting constraints

For example:Reply(Invitee , reply)

Meeting Deadlines

Working as part of a Team

JBoss Rules

JSP and Servlets


Installing Zimbra

Create Environment to Work on the JBoss Rules 4.0

Conflict using JDK 5 and JDK 6 with Tomcat 5.5


Project Outcomes

Simplifying the meeting scheduling process

Flexibility for the participants to choose their best time or even suggest new time
