[Edapt] How to migrate models serialized in binary files? [message #1087158] Thu, 15 August 2013 08:01 Go to next message

Hi all,

I've recently looked into Edapt and it actually looks very promising. We would definately start using it, but we have one major problem which seems to touch the core of Edapt.

For our purpose we need to serialize the EMF model instances in binary encrypted files. As I've understood, Edapt depends on the XMI serialization as it retrieves the meta-models namespace URI to retrieve the correct migrator.

Is this a known issue of Edapt? Any workarounds for this?

Thank you in advance!



Kind regards,
Niels Brouwers.

Have you tried your resources with Edapt?

I've never used Edapt myself, but I find that hard to believe.

I think this is a wrong conclusion. Any EObject must know its concrete EClass, which is contained in an EPackage, which,
in turn, must have an nsURI. XMI is not needed in that chain.

Just my 2c ;-)

Hi Niels,

I can't answer your question, but what I can tell you is that I have
taken up the maintenance for Edapt, as it died of a bit. I am currently
setting up the build process so we can be compatible with Kepler. The
code is now also in git.

https://git.eclipse.org/c/edapt/org.eclipse.emf.edapt.git/

Please feel free to log a bug EMFT / Edapt , it might be picked up by
the initial contributors?

Rgds Christophe

Hi Niels,

the original contributor is no longer actively developing Edapt.
Christophe and I recently took over to maintain Edapt.
There is helper methods to retrieve the namespace URI from an
XMIResource, but to my knowledge Edapt does not depend on the actual
resource being a XMI Resource as long as you determine the namespace of
the current serialization. (The actual migration method takes the
namespace URI as argument)
It would be great if you just tried it and report back here, thanks!

Cheers,
Maximilian

Thanks for all the replies. I will try it out and let you know my findings.


Kind regards,
