Can I think that a role defines which ISiteOperation are allowed to be 
executed
by ISiteControler#execute method?

e.g.
reader: - (no operation)
contributer - COPY, CREATE, DELETE, EDIT, MOVE

Does "ECM security model" mean the one of CPS?

I've added a method in the API

public boolean isOperationEnabled(ISiteResource resource, String
operationType);

Thanks. I will look into CPS and FileSystem provider.

RE: Local ECM Provider

Hi,

I drew a relationship between ResourceManager and db4o Local ECM Provider.
http://tmtec.biz/download/ResourceManager.jpg
Now that I have figured out an overview of ECM Resource
I'd like to know priorities ahead.

In order to pass the next phase(Creation Review?) of Eclipse Development Process,
what is important?

Reliable contributor names?
Reliable models?
Completeness of an initial implementation?

Can you send the account?

So most important is to improve specifications and start the code 
(detailled roadmap, etc.).
Supporters are also important, but hopefully we have enough to start 
(Special thanks to you and db4o, btw).

So it's time to improve technical specs and code components, now. The 
organization of the project will be improved by the time (following the 
Eclipse meritocratic model).
To start to code, I propose to keep it simple for now: point an 
component you are interested in, write some technical specs and discuss 
them, code! :-)

Re: Local ECM Provider


Hi Sato,

I've done some work on the UI level
Now you can browse the resource tree from the Apogee perspective.
A "New Site wizard" is available for nthe FileSystem provider - so you
can map a file system tree to an Apogee  site.
The model was refined - I hope to update the arch. doc soon to explain
modifications - and some problems in the Apogee resource model detected
when implementing the UI fixed.

The main modifications are:
- A Site is now managed locally by the ResourceManager - it is not
managed by the ECM provider - while ISiteFolder and ISiteFiles are
managed by ECM provider
The site  have a root that is a ISiteFolder and is mapping the local
site to a remote (ECM provider controlled) object tree.
- more high level listeners added
- changed the path from string to ResourcePath. I think I will change it
again  these days to IPath provided eclipse
- added extension point to define object types and resource UI adapters.
- created the UI adapter/view infrastructure - need optimization at
content provider level - for now each time getLabel() is called a lookup
for the resouirce metadata is performed which can be very costly on some
ECM providers since the metadata may be located on network.
I shoul do some caching at this level.
Anyway I think each ECM providers should implement a caching mechanism
for the metadata if looking it up is costly - since the metadata is
frequently asked at the UI level.
Anyway this could also be improved at UI level by doing some caching in

I was unable to test the filesystem provider, where do you configure apogee to add the new site wizard ?

You need the following plugins to test the UI perspective:

You can run Apogee as a IDe plugin or as a RCP application (the rcp app
is defined by the plugin com.nuxeo.apogee )
To see the resource navigator  enter the Apogee Perspective and then
create a new filesystem site from the new wizard menu:

New > Apogee Project > New File System Site

The user defined sites are persisted using db4o (see
org.nuxeo.core.resources.model.impl.SitesManager class)
Sites are stored in the db4o as SiteObject objects...

I will try to document all this at the end of the week

Re: Local ECM Provider

Hello all,

As many people sugested, we have decided that Apogee must support JCR specs.
This means a rework of the current resource model will be done this week
(and may be the next week)
The JCR model will not be used directly by the UI instead we are
preserving the concepts already defined (that are inspired from eclipse
model)
on top of the JCR resources tree.
This is so, because different JCR implementors may have different JCR
repository structures, node types, mixin types and logic.
So the only way to get an unified model is to make a small layer on top
of the JCR that let the propgrammer access the JCR repositories managed
by Apogee
in a common way by the mean of IFile, IFolder and ISite handles.
The ECM provider will need to handle the mapping between it's JCR node
types and logic and the Apogee model.
So a part of the current resource model will be refactored.
The new model will not force an ECM provider to be JCR compatible (so
the demo filesystem provider will normaly work with the new model) it
only adds native support for JCR.

Also the docs will be updated accordlying

Regards,
Bogdan

Re: Local ECM Provider

In fact, I found the problem, it seems it was a configuration problem. On my launching config, I did a "add required plugin" which resolve this problem.

Unfortunately, I now have a second problem, the following line throw a nullpointerexception setImageDescriptor( Activator.getDefault().getImageRegistry().getDescriptor("icons.wizban.new_site"));

But commenting it solve this, so it's working, but maybe not as it should.

Thanx,
Nico

Not exactly. Apogee will likely use the Eclipse Trust Framework 
(Higgins), that allows to define mapping between the Apogee model and 
other security models.
But clearly, we are inspired by the Zope/CPS model and are looking for 
other model example. The advantage of the CPS security model is that 
it's well-tested, easy yet powerful. It's based on a Permission/Role 
system (objects/method define needed permissions; roles are a collection 
of permissions; roles are applied on users in contexts/areas).

Content Objects will define workflow actions available on them, provided 
by the ECM server.

Do not hesitate to ask more, if it does not answer to your questions (or 
if it's not clear enough).

Thanks,

EB.
