Re: OCM mapping to nt:file
Hi Christophe,
i am also interesting to use OCM, and your examples is really valuable for
me!
Could u pls answer on some more questions:
1. Is it possible somehow to make mapping from/to CND-file <->
JavaClassWithAnnotations?
2. How to use OCM with WebDav protocol? Can I open somehow the JR-Session
via WebDav at all?
3. How comparable RMI- and pure-jcr-API in OCM view? Looks similar, but...
4. Is it possible to update already existing mapping in repository somehow,
when the class-definition is changed? If not - what is the "best practice"
for such cases?
thanks in advance,
Vasilij

Right now, this tools generates node types from an OCM xml mapping file.
This is not yet possible to do that from the annotations. Yet another tools
to write ... :-)

I advise to review Sling which is more appropriate for that kind of uses
cases.
See on http://incubator.apache.org/sling/site/index.html.

Yep, for me, this not clear how we can manage the different situations. I
have to think about that in more details.

Yes. this is another OCM project. Jackrabbit OCM makes a full abstraction
on JCR which is not the case of JCROM. JCROM is more simple to configure but
it seems there are less features (for the moment). Fore exemple, Jackrabbit
OCM support interfaces and ancestor. It also support many Collection and Map
types. I'm not sure this is the case of JCROM. I will add a page on the
internet site with a full feature list.
Hope this help :-)

Hello again,
Thank's for your answers, now it is mostly clear for me.
CND : You say -"" CND : not yet supported. ..."". Does it means i can
generate java-classes from XML-structure with OCM-compatible annotations?
Have u link to impl/doc/example?
RMI - Webdav : in my case i have already geterogen-enviroment (for
ex.different JVM-version). Additionally in the nearest future i want to use
it not only for java, but for JS, .NET. So WebDav as independent protocol
looks much more flexible.
Update/modification in the content model : "removing properties"? Is it
helps when i have already stored into REPO data, and then i want to change
"a bit" the TypeDefinition ...
...for ex. in your example resource i want to add 1 field and rename 2nd .
Currently we export context of old repo and convert it by XSLT into new
structure, then store into repo back. But it is look not fine-grained as for
me.
BTW: I just found the project http://code.google.com/p/jcrom/ JCROM .
Is it related somehow to OCM-development? Looks pretty similar ;)
Kindest regards,
Vasilij

Hi,
I think we are in a second dev phase for the OCM tools. Many features are
implemented and now I more focusing on simplications, check some uses cases
and wait for the community feedback.
So, all you are asked are tasks to be implemented or to check.
CND : not yet supported. I know it becomes urgent for some of you. I think
it is possible to make a small patch in the OCM node management project.
RMI - Webdav : we need to add more doc and examples. Personnally, I never
used the webdav support in my projects. RMI is certainly not a problem.
Update/modification in the content model : this is not yet supported. There
are different possibilties. Adding properties or subnodes should not be
complex. What about removing properties ?
br,
Christophe
