Again, an example of a top level project. Works well for small top level

Anyway, my vote is non-binding but I still think it will lose developer
value in favour of an insignificant user value.

WDYT?
<Answer on naming>
I was the one who defined both the names we use in our pom.xml, the id
* For names: XWiki Commons - Extension - API
* For ids: xwiki-commons-extension-api
* For directories: xwiki-commons-extension-api/
I've been told that we prefer to use simpler names since the hierarchy
already
contains the information about the project. This proposal (which is
not yet implemented but decided AFAIK) initially came from the fact that
long directory names don't work on Windows.
It's the same for names. You don't need to have the full "path" in a
pom.xml name to know where it's coming from since it's contained in a
pom.xml which has a location.
* For names: Extension API
* For ids: xwiki-commons-extension-api (we need the full name for id
since we use
a fixed groupid ATM. We could drop the first path though if we
really and have only "extension-api" since the group id is
"org.xwiki.commons" but since this is a technical id I'm not sure it's
a
good idea and it's not the topic of this mail anyway ;))
* For directories: api/ (more precisely:
commons/extension/api/)
Thus using short names is not shocking at all. To be honest I doubt
anyone is
really using the name when developing. Having a short name
wouldn't be an issue.
FTR Maven POM Reference (http://maven.apache.org/pom.html) says the
following about the <name> element:
"
name: Projects tend to have conversational names, beyond the artifactId.
The Sun engineers did not refer to their project as "java-1.5", but rather
just called it "Tiger". Here is where to set that value.
"
The name is not supposed to be an id. There's artifactid for that.

</Answer on naming>
I think the main point where I have not been clear is that there has
never been
any intention of having XWiki modules displayed flat in the
Extensions Home Page livetable :)
If that had been the intention then we would definitely have needed a
long name to
group stuff together. But again it's not the intention at all.
Why not? Simply because it doesn't scale and would mean showing lots of
stuff to users, flooding them.
So we need to talk about what we're doing now and future…
* Now: We only display modules that are either relevant to the user (ie
that they
can download) or modules that are used as documentation points.
We're not planning to import all modules. The idea is to continue importing
only extensions useful to users or top level modules to hold the
documentation for that module.
* Future: I think the best representation for the future will be the
following:
- a treeview when you wish to browser everything.
So to take the example
of "XWiki Rendering - Macros - HTML Macro" it
would be under the XWiki
Rendering/Macros/HTML Macro tree nodes
- if you start typing letters in this
treeview-livetable widget you'll
see all the extensions matching the letters
you type, in a flat view (no
longer hierarchical)
- we will continue to have tags to provide
categorizations of
extensions: for example "'Macros",
"Applications", "LDAP", "HTML", etc
- we will also need a view (probably the default
- the treeview would be
a tab to click to get it) which is a flat view listed by
user ratings. So
the most used extensions will get better ratings and will show at the top,
thus making the more technical or less used extensions got at the bottom of
the list.
- When displayed in flat view, we could easily
display the location of
the extension on the next line in smaller characters and in
grey color
instead of black for example (to make it less visible)
To conclude: it's very important that we have a pretty name as the name.
This
is the intent of Maven's pom.xml <name> tag. The hierarchy is provided
by the <parent> information and can easily be gathered and displayed,
whether you are in maven (mvn dependency:tree, your IDE) or in the EM UI.
> P.S.: I`m +0 for the new proposal, since I am quite happy with the
current
setup.
What new proposal?
