Hi devs,
I would so much like to commit XWIKI-4775, at least in 2.3. So, we for the
separators, so far we have:
1/ wiki:Space.Page^objectName#property
1 +1 (I recorded Vincent here), 1 -0.5, 1 -1
2/ wiki:Space.Page:objectName.property
1 -1, 1 +1
3/ wiki:Space.Page^objectName;property
1 +0.5, my +1 which I will change now
4/ wiki:Space.Page^objectName.property
2 +1
5/ wiki:Space.Page^objectName^property
1 +1
My +1 goes for 4/ which I will commit soon if nobody has anything against it.
Seems that 4/ has won. Closing the vote, starting to prepare XWIKI-4775 patch
and commit for 2.3M1.
Thanks,
Anca
Re-explanation of the thing:
As a result of the discussion at http://markmail.org/thread/uj34lvnjgrnlf6vm and
some other live discussion, we concluded that we would implement the objects and
object properties references _as if_ every entity had a free name (unique, human
readable string name to identify it among all other entities of the same type in
the same context). However, for the moment we don't have a good approach for how
_exactly_ to name objects, so we won't implement a specific way to name them,
we'd have the support for generic object references but not the names
themselves, which would be the responsibility of the application _actually_
using the object references (none in core, ftm, only annotations on sandbox). To
get a flavour about how this would happen at this point, take a look at the way
IndexedObjectReference [1] in the annotation references module extends the
ObjectReference[2] in the patched model, to implement a specific way of naming.
Now, in order to actually commit XWIKI-4775, the support for generic object
references (with unspecified name), we need to agree on a separator, which would
be harder to change afterwards, when we decide on the actual name.

Thanks a lot for the help,

Hi all,
I would like to go ahead with committing
http://jira.xwiki.org/jira/browse/XWIKI-4775 before the 2.2 final release
(because I would like annotations to work as clean as possible on 2.2 final).
In order to do that, we need to agree on a set of separators for the object name
and property name.
There have been the following proposals so far:
A wiki:Space.Page^objectName#property
B wiki:Space.Page^objectName$property
which has received some votes in http://markmail.org/thread/uihq4mmwgaufbcz6 but
I personally would stay away from # and $ separators since they're reserved
characters in velocity scripting language and it might be uncomfortable for
using refs in scripts.
Also, we had:
C wiki:Space.Page^objectName;property
and also:
D wiki:Space.Page:objectName.property
Which one would you prefer? Any other proposals?
Any separator should be easy to implement, and roughly anything could be used as
a separator (so feel free to propose).
Note that there is an alternative to this, to make annotations implementable on
2.2: only add the two entity types (Object and Object Property) along with
making the string serializer and string resolver extensible so one could add its
own separators for the 2 new types.
WDYT?
Thanks,
Anca
