EML2 Editor

[Dan Higgins]

Hi All,

    There is now a 'pre-beta' version of a free EML2 editor that some of 
you might want to look at. To try out this currently-existing eml2 
editor, download XMLEdit.zip from

http://www.nceas.ucsb.edu/~higgins/XMLEdit 
<http://www.nceas.ucsb.edu/~higgins/XMLEdit>

Although eml2 was released some time ago, the only ways to create an 
eml2 document have been to use a text editor, perhaps use the eml2 
export function in the released version of Morpho, or use a commercial 
software product like XMLSpy, Commercial products are expensive, while 
using a text editor requires an effort to understand the structure of 
eml2 before one knows how to create valid eml2 documents.

The above link connects to a zip file which, when expanded, results in a 
directory called XMLEdit. This is basically just a version of the Morpho 
code with a greatly speeded-up XML editor. If you expand the zip file 
and then start the program using 'editor.bat' (on Windows), you will see 
a screen similar to that shown below. (A Java Virtual Machine, version 
 >= 1.3,  is required.) [Actual, the screen shown was created by 
clicking the .New EML2'  button, and then expanding the resulting tree 
on the left.]

As can be seen, this eml2 editor can display the entire potential 
structure of and eml2 document along with the help information for the 
various elements. Various sequences and choices defined in the eml 
schema are also displayed in the tree on the left. It is thus thought 
that this can be a useful tool for anyone trying to understand the 
structure of eml2, in addition to allowing one to create eml2 documents. 
Just fill in the elements of interest and save the result.

Again, it is emphasized that this is a very PRELIMINARY VERSION. It 
almost certainly has 'bugs'. However, the tree display of the eml2 
structure has been very useful to me and may be to others, even if there 
are some problems with the code. Please feel free to ask questions, 
report problems, etc.
