Hi,
I'm looking into the direction to make the data mediation pluggable into a
system service which holds a registry for all the mediators. Then the usage
pattern will become the following:
1) Get the data mediation system service (can be done by injection on
"autowire").
2) Transform the data from SDO into one of the XML representation (such as
StAX, DOM or JAXB) (The transformer can be looked up by the source type and
result type).
Thanks,
Raymond

Hi Raymond,
I think the question to be answered is how this data mediation is supposed
to be used. For example, shall I use this data mediation as a java util just
same as how I use SDOXMLHelper.java before? In this way, the data mediation
might look like a replacement or enhancement to SDOXMLHelper.java (and other
similar helper classes). Or, as one email suggested, do not embed this into
SCA core, instead make data mediation act as a pluggable system service,
which can be used in a wilder context, such as content-based routing, data
transformation etc.
Cheers,
Jervis

Hi,
Do you think if my prototype can be used as a seed to flush out a good data
mediation story? If so, does it make sense that somebody commits it into the
sandbox to get more people involved? I'll update the wiki page as I add more
things.
Thanks,
Raymond

Hi,
databinding module in sandbox is not included as part of build at the
moment. Are we going to still have this module in the new core?
I think so, yes.
In Monday's IRC chat, Jeremy mentioned that we need to fix the version in
the sdo databinding pom, is anyone working on this right now?
I'm not. Raymond also had a patch for it that I should apply - it's
just that it is related the the type helper hierarchy issue that we
still need to resolve.
Also SDOXMLHelper.java is missing from sdo
databinding(java\sca\databinding\sdo\src\main\java\org\apache\tuscany\databinding\sdo\SDOXMLHelper.java
in M1 repo). Is there any reason why it is not there?
No - it could just be that the code was copied before it was added.
I will need this class to do the conversion between xml stream and sdo
object in Celtix binding. Or maybe, we are going to the DataMediation
proposed by Raymond?
I think we will do something like that. I've not fully grokked Yang's
mail on this yet (the streaming one).
