Hi,

I am interested in the Texo XML/JSON REST Web Service Support.
I did some web research and also searched this forum, but I could not find anything related to using Texo together with CDO. I'd like to ask some questions:


  • Can Texo be used with models stored in CDO?


The following questions make only sense if Texo supports accessing CDO models:


  • How does one specify the CDO repository and the resource within to access?
  • How does Texo handle write access (CDO transactions)? Does it use automatic commits on a REST PUT operation?
  • Can Texo support manual commits/rollbacks on CDO transactions.
  • Can Texo support access to (historic/audit) views.
  • Can Texo support user credentials (login,password) when working with CDO?


Thanks in advance!

Hi Lothar,
The short answer is no...

The longer one: there are possibilities to develop this. Texo provides also a EMF <--> JSON converter and CDO objects
are EMF objects. Converting a plain object into json is quite simple, were it gets tricky is in resolving references
while de-serializing (so that objects which already exist in the db are read) and making sure the proxies have the
correct resolvable uri's when serializing.

But not sure who has time to do develop this functionality, it is a nice task to take on for sure. Maybe a contribution
or sponsored development would help. :-)

gr. Martin
