The XML Data transformer will be a buffer between the
application code and the actual transformer
implementation. The actual implementation might be
Castor, JAXB or Digester etc. The implementation will
be selected based on users setting be it System
Property, Services Discovery etc. Very similar to
Commons-Logging.
I have done some coding since I think this is very
useful.
And By the way, I checked Morphos and there wasnt any
code available in the CVS.
Thanks,

PS : There arent EDI - Java open source transformers
yet. However there is a sort of freeware called
OBOE (Open Business Objects for EDI) from
americancoders.com
I like this idea. Would this be a front end to things
like Castor and
Digester, or would they move to this component?
Also, do you already have a codebase you have in mind
for this?

P.S. Out of curiosity, are you familiar with any open
source EDI
transformation code?

Data Transformation is essential part of day to day
computing, whether it is xml-to-xml transformation,
xml-to-java transformation, edi-to-java transformation
etc.
Lets take a simple example of xml-to-java
transformation (or vice versa)
There are several implementations : Castor, JAXB to
name a few. Usage of these introduces dependencies on
the implementation.
This immediately draws similarity with commons-logging.
Commons-Logging acts as a Adapter between the user code
and the implementation, freeing the user code from
Log4J and J2SE Logging imports. (Thus allowing plug and
play logging at the code level.)
A similar approach for Data transformations in general
(xml-to-java objects in particular) is highly
desirable. Programmers like to access in memory Java
object representations of external data.
Hence I propose a Commons Data Transformer, freeing
the user from implementation specific imports. I
envision Commons Data transformer will perform
x-to-java (direct transform) and java-to-x (inverse
transform) transformations.
PS : It is interesting to note that certain kinds of
Configuration are really a subset of data
transformation.
Thanks,
