Hi there !
I'd like to inform you about the Vala/GObject port of the W3C Widgets
parser I am currently working on.
This port will allow the use of the parser within "native"
applications. I choosed Vala for the similarity of its syntax with
java.
This is straight port using
* libxml2 for parsing instead of JDOM
* glib/gio GFile for file handling instead of java.io
* libuuid for GUID generation instead of the custom code found in
util/RandomGUID.java
* libsoup for HTTP client instead of apache commons
Cool!
I was wondering if such a port is fine by you,
Definitely!
and what are my
obligations regarding licencing : should the code stay Apache licenced
? If so, is it ok to depends on LGPL libraries ? Will it be legally
usable by GPL-licenced applications ?
It depends on how you want to distribute it. In general code using the ASL is
compatible with GPL, but not vice-versa.
The FSF has declared ASL 2.0 to be compatible with GPL3, but GPL (any version)
is not compatible with ASL.
For more concrete / definitive description of what licenses are and are not
allowed at the ASF,
see: http://www.apache.org/legal/resolved.html
If you'd like to contribute the core code to Wookie (e.g. in parser/vala/) then
it has to use a compatible license. You might also be able to contribute your
source code to Apache with an Apache License but then create a binary
distribution with dependent LGPL libraries hosted externally (e.g. Apache
Extras or your own Github/GoogleCode/SF site)?
To be able to contribute such core code to Wookie it also cannot have concrete code dependencies (e.g. api wise) on non-compatible licensed
external code/libraries, even if these would be hosted externally.
LGPL licensed code/libraries are not compatible and cannot be brought into
Apache nor released from Apache.
If you'll need such direct binding to non-compatible dependencies within core code you'll either have to rewrite them to become independent
or properly decoupled to be able to bring this within Wookie itself.
Note that it might be fine to combine ASL and LGPL within one project, just not
at Apache.
Hosting such a project at Apache Extras (http://www.apache-extras.org) would be fine though, with the added benefit of strong affiliation
with a related Apache project.

I wonder if this something our mentors here might be able to comment on..?
Anyway, thanks for your great work, it saved me tons of time !
Sounds great!
