Open Source Photography

Thanks to Alex Prokoudine, I ran through this wiki Open Source Photography. It is a user oriented website. Interesting.

exempi 0.5.0

I took some time to release exempi 0.5.0, my library to parse XMP meta data. The C API is in there, the C++ API will come later.

Download .tar.gz - GPG signature

It is LGPL licensed.

New job

As Michael mentionned Monday, I joined the OpenOffice team at Novell. I'm thrilled and I would like to thanks Novell for offering me the opportunity to work on a major Open Source project.

In the mean time I have been added to both Planet OpenOffice.org and Planet SuSE.

So I have been having some spare time lately, and last week-end I boostrapped a new project: exempi. exempi is a library to deal with XMP metadata.

But what is XMP? XMP stands for eXtensible Metadata Platform. It is a standard, created by Adobe, to define an extensible storage for metadata. XMP is based on RDF (and therefor XML) and encompass EXIF, IPTC4XMP metadata[1], Dublin Core and other metadata models. It is now part of the workflow for digital photographer and supported by various software package used in the industry.

Today, Adobe provide a SDK as a source code library to read and parse XMP, but unfortunately the license makes it incompatible with the GPL license[2]. And I couldn't find an XMP library[3]. Since libopenraw needs a standard way to be able to extract the metadata, that are mostly EXIF, but not only, I decided that the best solution was actually to go with XMP.

What are the plans? The current plan is to have a library that provide a way to access to this structured information extracted from an XML blob. That way it is easy to validate against the XMP side car files that I have. Sidecar files are XML files containing the XMP metadata, that are stored next to the file they refer to. This is the conservative way to store metadata, even more important when it is for read-only files like digital camera RAW files.

More about that later, as the XML parsing code is not finished.

As for the behind the scene, exempi is written in C++ and will have a plain C API. The license in LGPL.


[1] which supersede the IPTC IIM

[2] IANAL so don't take this as a legal statement

[3] I could actually find a couple of utilities, including a metadata plugin for Gimp

The intent of this post is to be humoristic

ELR had a strip about GUN/Linux.

Now Eric announce that he abandon Fedora for Ubuntu. I think that Alan Cox pretty much summarize it well.

Will Ubuntu be renamed Gunbuntu?

Thin clients

Another thin client. This time it is the Canadian company Koolu (just ignore the proprietary Flash like I did). The interesting thing is that they run Ubuntu and OLPC (choice) on it, booting via PXE. OLPC is potentially the biggest deployment of AbiWord. The machine is still able to run big software like OpenOffice, and even has an optional hard drive.

Another interesting thing is that they have John "maddog" Hall as a CTO.

Linux phone

The OpenMoko software platform has been released. OpenMoko is the the project initiated by FIC in Taiwan. Apparently the hardware is late, but they released the software still.

On the other hand, the Access Linux Platform has been released, and its openness looks much less appealing. ALP is the successor of PalmOS and is based on Linux.

They are both based on Gtk+ for their toolkit. That open more deployments for AbiWord.

Congrats Dodji #2

Dodji, congrats on your new job. All I can say is that I'm very envious.

gthumb raw thumbnailing

Following the experiments with gthumb, now that libopenraw 0.0.2 has been released, I commited my patch to partially fix gthumb bug 145564

I'm wondering if it wouldn't be smarter to bring this feature down the stack to the Gnome thumbnailer.

New Advogato Features

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.

Keep up with the latest Advogato features by reading the Advogato status blog.

If you're a C programmer with some spare time, take a look at the mod_virgule project page and help us with one of the tasks on the ToDo list!
