[Hypercontent-users] Adding a custom editor

[John F. <ja...@co...>]

How difficult would it be to add a custom editor to hypercontent?  Here's 
what I have in mind.  One of the cool things about HC is the navigation 
editor and I was wondering what it would take to extend that functionality 
to allow edition of a more complex xml file.

I have a site that contains two or three pages that include some common 
content, in this case information about releases that are available for the 
project.  Rather than edit each page which contains information about 
releases I thought it would be useful to have an editor which just edited 
the release information and then use an appropriate stylesheet to render 
the necessary content on each page.

For example, let's say my xml looks something like this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE release-template SYSTEM "/config/dtd/releases.dtd">
<releases>
    <release version="2.5.1" stable="true">
       <label>QuickStart</label>
       <type>GA</type>
       <date>2005-10-19</date>
       <download>
          http://www.yale.edu/its/tp/portal-dist/251/quickstart/uPortal_rel-2-5-1-quick-start.zip
       </download>

If a custom "releases" editor could be created it might present a page 
somewhat like the navigation editor that would allow me to "add" a 
release.  Then I would get a form which would let me fill out the 
attributes and nodes I described above.

Has anyone done anything like this?
