[Zope-CMF] Tasklists, versioning and personal calendars for cmf

[Heimo Laukkanen]

Hi all,

I've done a really fast extranet for the purpose of managing projects 
in one shared workspace with clients. Putting it together with CMF was 
a piece of cake - just modifying some skins and doing a few scripts. 
Apetite grows while - for me and for users - while doing these things 
and a couple of interesting questions and ideas have risen.


1. Personal / group calendar

This is something that could be done in a million different ways, but 
basicly I am looking for no fuss solution that could be easily 
maintained while CMF goes onward.

My first thougth was to inherit or modify calendar and events to suit 
these needs. Additional fields for event that allows me to set certain 
event for person or persons, set a due-date and ? And then create 
helper functions to the calendar tool for creating calendar views 
where some events overlap - check wether a user has available time on 
a certain timeslot etc.

That would be nice. Any thougths wether there is any idea for doing 
this? What would be good design choises?


2. Tasks /  Notification

While doing projects with busy people, one thing that would help - is 
a possibility to give tasks and make notifications by email about 
something that has to be done - for example I migth want to send a 
document for a group of people to be read - and to know, when they 
have read it and / or commented it.

DC Workflow - having a workflow variables to store info about to whom 
the task goes to or something similar? Any thougths or ideas how to 
look into this?



3. Versioning of documents, multiple languages

This propably falls to the category of modifying the undo feature and 
clever usage of workflow, but still. There are situations - for 
example while doing production of multi language magazine, where both 
the client who orders the magazine, people who have been interviewed, 
translator and editors need to work with the same documents. Comment 
different versions and track changes - make sure that changes happen 
in all different versions etc.

Now one thing that would help, would be a document type that would 
have easy history buffer - with a possibility to render what changes 
have happened in each step. Anybody say CVS? ,-) And a really easy to 
use interface.

This whole versioning of documents is something that I would like to 
stay out of, since I have so little knowledge of it at the moment - 
but it would be nice to hear, if others have had some good experiences 
and solutions - that non computer people have been familiar with.
