[Geotools-devel] Re: editable Web-GIS

Hi Tom,
I don't have answers to all your questions but have copied the email to the 
geotools email list where you may get more help.
Comments inline.

Is a java application suitable?  Java applets in browsers are almost 
impossible to make bug free across all browsers, and tend to be large to 
download.

Are you tied to using ArcIMS/ArcSDE?
The current development for geotools2 is focusing on using GML.
The ESRI shapefiles used by ArcIMS should be easy to port across from 
geotools1, and is on the geotools2 "to do" list.

Happy to give you hints, especially if you are also offering to help out with 
coding. :)

If you decide you want to help out with geotools2 development, I see 2 things 
that you could help out with:

1. Implement a data interface for ESRI Shapefiles.
2. Implement a data entry/edit GUI for geographic shapes.  (This could 
possibly be ported from the GIS Toolkit.

Considering people will help you with this, I suspect you should be able to 
get a prototype working by July if you work hard at it.

I'm not quite sure what you mean here.  The open GIS have defined a framework 
which can be used for web based, inter-operable GIS data entry and updates.
The concept is based around a "Web Feature Server" - WFS.  You can find a 
draft specification for this at the OGC website.

Rob has developed an open source WFS (although I don't think it allows 
updates yet), and geotools2 is working on developing a WFS client, which will 
allow editing features from a WFS.

However, this may be more than you require if just want to edit a proprietry 
file format like ESRI shapefiles.

I'm not sure what the Highlight Manager is.

Looks impressive.  However, I think it is just a viewer.  I can't find any 
data entry functionality.

Me too.  Keep in touch, and I suggest you join the geotools-devel email list.
