W3C | UROP | Jigsaw

Calendar

Project description

The Project Peter will be working on for his summer UROP at the World Wide Web Consortium is to write a shared calendar resource accessible over the web. This resource should be able to accept and display information in a variety of forms. He will need to know Java, Perl, and the workings of the Jigsaw server in order to complete this project.

Summer UROP Proposal (Kinda corny, I know)

The intent of my summer UROP with the World Wide Web Consortium is to create a fully functional shared calender resource. This calender will be accessible over the web, and multiple users will be able to input important dates and events on the calender, and then the cal- ender will notify them when they have something scheduled. The final product should be able to recieve, display, and send data through many different means.

Over the 11 week period there are three goals I will accomplish during my UROP. The first is to learn all the tools I will need to work on the project. I will need to learn Jigsaw (a HTTP server written in Java), how to create new resources in Jig- saw, and the Java programming language. By the end of the first couple of weeks as a test to see if I have accomplished my first goal, I will make something that runs inside the Jigsaw server. My second goal, which will take the majority of the summer to accomplish, is to make a functional calender. It will not have all the features of the complete calender, but it will have the important ones. The calender will be accessible over the web and by multiple users. My final goal will be to finish fine tuning the calender. It will be able to recieve, send, and display information in many different ways (the main ways will probably be through e-mail, or directly through the web site). The calender will then be used and tested by people at the World Wide Web Consortium and I will get feedback on how to improve the calender resource.

There are many benefits I will get out of my summer UROP experience. The first is I will learn about human interface, groupware, and personal information management while creating this calender. I will learn how to make programs more useful for users, the best ways to display data to users, and what users really need in a program. Another benefit I will gain through the UROP, is learning to do real Java development, at this point in time I have just been fiddling around with Java, but once the summer is through I should be a very competent Java programmer. And the final benifit is that I will be working with the World Wide Web Consortium, and I will be doing actual software engineering. This is the first time that I will be working in an environment like the World Wide Web Consortium and it should be very rewarding.

Tentative Mile Stones

Aug 20 - Sept 20, 1996
Test the code and make revisions and additions.
June 24 - Aug 20, 1996
Code the Calendar.
July 19
user interface demo
July 3
minimal functionality: enter an event, view it
June 3 - June 24, 1996
Learn Java, Jigsaw, and Perl.

Status/Log

Calendar in Progress- will not work sometimes as I alter it-http://wave.w3.org
August 13 - altered the code so it will work on the lastest version of Jigsaw, took out the stipulation that the creator can only edit an event because it is too restrictive and everyone at the w3c should trust everyone else, you still need a password to get in though.
August 12 - made it so the calendar shows multiple day events on the month view. Finished first version, going to show it to people.
July 30 - added event ownership, password protection can add events through e-mail (have to make it so that the mail program can get through the password protection), people and groups now have address, e-mail, full name, and phone number fields. Added url field to events, making setup program, it is thread safe, made the sorting program binary.
July 19 - most of user interface is done, can add, edit, remove, and view dates somewhat easily, spent the last two days looking for a bug, not fun, not productive, but found it and fixed it. The algorithm for searching and sorting is still n^2 will work on that, and I can make it more efficent in area's.
July 3 - Redesigned storage scheme, every event is now a jigsaw resource, Created a URLAttribute which is basically a StringAttribute to store the URL with a static method which will find the URL for you, also made a StringVectorAttribute, not sure it was all that important but it is a bit easier to use than using a StringArrayAttribute in some cases.
June 16 - Working on the front end now, basically I'm making the Calendar out of a bunch of subclass of the PostableResource class, I have made a Calendar generator in which the user gives it a month and a year and it makes a Calendar of that month. information, and learning about Jigsaw
June 12 - Decided to use DBM for now, maybe something more sophisticated later on.
June 10 - Finished mail parser. Trying to figure database scheme for
June 3 - Learning Perl and writing mail parser.
