Does it include an automatic editing interface easily accessible to
yes, we are working on a editing interface to make this easy.
If one believes the hype then using W3C Schema should also allow for
use of "generic" XML editing tools.
I have used XML Spy (a commercial product) which does validate as you
prepare the instance document. It lets you know via the GUI what
elements and attributes (and restricted attribute values) are
available at any particular level in the instance document, but I'll
be the first to admit it's really a tool to help experts (not novice
users) prepare documents.
Other tools might also work. For example:
*XAmple XML Editor <http://www.felixgolubov.com/XMLEditor/>
/Description from the Publisher/*
/Java Swing based XML editor that analyzes a given schema and then
generates a document-specific graphical user interface. Unlike other
XML editors, the XAmple XML editor GUI exposes not just a tree
representation of the XML document but rather a logical combination of
the XML document and respective XML Schema. To be able to prepare
valid XML documents of significant complexity, a user is not required
to be familiar with XML and XML Schema languages and to have any
a-priori knowledge about the documents structural requirements./
I have not tried this as yet, but I will be trying it out in
conjunction with the new LAS XML schema we're developing. Anybody
else have experience with this product or others?
heres an interesting POV:
Editor's Note: This article is based on the closing keynote speech that
Edd Dumbill delivered to the XML Europe 2004 conference in Amsterdam./
To conclude, I'd like to celebrate a few of XML's qualities that endure
and make it the truly unique technology it is.
* Intimate relationship with the network: XML's coexistence with the
Web has unlocked a great deal of power in developing distributed
applications. The simple concept of the URI, in particular, has
facilitated both elegance and potential in XML applications.
* Human readable and editable: This aspect of XML cannot be
underestimated in importance. In 2003, over 80% of developers
surveyed by XML.com used a text editor to create XML, even if they
used another tool, too. The adoption of simple forms of documents
on the Web, such as HTML and RSS, is a testament to this. A
successful document type is manifestly a readable document type.
Microsoft gets this one, too: look at their latest XML creations
such as XAML and the WinFS
metadata notations. They've come through the complexity fire back
down to readable markup. (As an RDF fan, the realization of this
truth causes me some pain. The way out is to stop thinking of RDF
as an XML application, and look to easier syntaxes such as Turtle
<http://www.ilrt.bris.ac.uk/discovery/2004/01/turtle/> and N3
* Dedicated individuals who keep the flame: Were it not for our XML
heroes, we'd be mired in second-rate, committee-led technology.
The number of those on this list is continually growing, and we
ought to be thankful for them.
