Java soon to be opened !

Here is a good news for Nuxeo 5 : Sun CEO sets open source Java time frame

As we read in a few discussion threads after the release of  NXRuntime and Nuxeo Core, some people were pointing out that, with our Java switch, we weren't using a full open source stack anymore. These discussions will be over soon.

As well, some people asked us if we considered making Nuxeo 5 running using gcj. Well, ... we have been trying to leverage gcj with the NXLucene project where we were using Lucene through gcj. This is working ok but what a pain... It appeared to be extremely complicated to find the right version of gcj depending on the target platform on production and that caused us lots of worries... So definitely not a viable option. Ask the hosting companies if you are not convinced ... As well, a lot of work is required at application level while trying to port gcj-based application on upper versions of gcj because of bugs in the compiler itself. So much frustration...

Furthermore, we can expect Java enabled Linux distributions out of the box in the future with Java applications pre-installed and shipped with the distribution itself : for instance JBoss AS.

Because of the fact that Nuxeo bas been caring about open source for more than 6 years, playing the open source game and choosing a core business fully based on a transparent open source model, we are more than happy that this time frame set announcement comes up almost at the same time as the release of Nuxeo 5.

Nuxeo Core 1.0 released !

I'm proud to let you know that we released  Nuxeo Core 1.0 !  This is the first release of the new embeddable document management core that is the foundation of the upcoming Nuxeo 5 ECM platform.

Nuxeo Core is an embeddable document management core, based on Nuxeo Runtime. It provides all necessary low-level services to define, store, manage, audit, request and search content. It is the kernel of Nuxeo 5 and can also be embedded in third-party applications to provide advanced content management features. It can run on any Java platform, can be easily extended using plug-ins (thanks to Nuxeo Runtime) and implements JCA (Java EE Connector Architecture) to be easily plugged into existing applications or information systems.

Nuxeo core key features  :

• Model: content management concepts definition
• Storage Manager: low-level content storage and retrieval (JCR-based)
• Schema Manager: XMLSchema based content schema definition and management
• Version Manager: versioning management
• Content Type Manager: content types management (a content type is a set of schemas)
• Query Engine: SQL-like unified query engine
• Security Manager: access rights manager and controller
• Life cycle management: define, deploy and applies life cycle on document types (JCR storage)
• Event Service: abstract event service to broadcast and receive events
• Local (POJO) and Remote (JavaEE) access using dedicated client sessions.
• Set of extension points allowing third party code to extend and customize the Nuxeo Core services

You will find detailed information here. This is a detailed technical overview of Nuxeo Core 1.0.

A JBoss binary release is available along with a simple Eclipse RCP demo application that leverages the Nuxeo Core. (The demo application is available for Linux, OSX and Win32). You will find in this document all the needed information related the Eclipse demo application.

Check the project homepage for more information and especially if you want to check the source code.

This is an important step toward the release of Nuxeo 5 planned in the middle of next month. We are all more than happy and proud of this new platform and we hope you'll enjoy it as well !

Stay tuned there is a lot in the pipe ! :)

Open source ECM business breakfast was great !!!

The business breakfast we set up with Euriware las week was a great success !!! We were in a nice room opening on a fancy garden at the House of Latin America. We enjoyed presenting our open source ECM solutions and business offers. But I have to confess that we encountered a little problem... There were not enough chairs and a lot of interested customers :) Trust me I love this kind of problems!

Next month, I'll be in Bamako to talk about the interest of open source ECM in Africa and in Berlin to present Nuxeo and our business approach during the JBoss World.

Stay tuned!

OOo Extensions Project Hot Topics

After the OOo 2.0.4 annoucement that provides new extensions improvement such as licencing and new extension .oxt, the extensions team is hard working setting up an ecosystem for developping extensions

The main points actually worked on are

• Translation toolkit : A long discussion has occured focusing mainly on the backend storage format (xml xcu OOo file format, po files, java properties format). While this is important the main focus regarding Extensions usability is to give developpers a cool and simple API to use and translators of every skill level a versatile tool to provide and test translations
  It seems something is beeing studied at Basic IDE level but this rather a new sun internal project and will be limited to dialogs translation on first release. This may be available in OOo 2.2+ and probably not downward compatible.
  As a short term solution, our great Paolo proposed a solution based on pyUNO and xcu file. it is a cool way to go as it will allow extension developpers to have their work being used in OOo 2.x versions and this toolkit can even be enhanced to support other file format.
• About deploying extensions, the actual command line based utility is rather secure but restrictive. It does not allow to use an existing library repository. The problem is that it sometimes behave too silently when de-activating some extensions. Some ideas (use of xlc files) and context restrictions are being discussed to see if something can be improved for user experience
• A new tool demonstrated at OooCon is now available - This NetBeans plugin is really cool and i think that an Eclipse one will also be available :) 
• A small team is setup for the web site - A great Art design work is being started by Ben while Jean-Pierre setups a first prototype. This will be available really soon as an alpha proposal release when server will have required tools
  

if you wish to join the Extensions team, please do. Everybody is welcomed, just tell us, we will find something for you ;)

Speaking about extensions, one as to note the new Sun Java OOo Blogger. This reminds me Caolan's work from last year. The same goal, done and freely available in pyUNO. It is freely available as a study case and use. I bet originality will be for the next extension. But if you want to fund SUN for supporting OOo, it is a way ...

At OOo level, a new team is built for a Creative Commons licence inclusion in OOo documents. If you whish to help visit them on their dedicated mailing list

And for volunteers, I give here some rough ideas for extensions. But, everything else is possible :)

• an impress autostart : OOo does not have a pps-like file format. The idea is to define a DocumentInfo.Info1 parameter, check it though a resident extension on impress file opening and auto start the presentation (level required : easy/medium)
• on-the-fly translation : on the model of OOoWikipedia, retreive the translation of an hilighted word and display it in OOo (level required : easy)
• S5 is a web based light format - create an assistant/filter allowing to export impress files to this format. mainly XSLT stuff but a wizard can also be setup (level required : skilled) 
• logo is a cool language for children to start with. OOoDraw API could be used to embedd such a tool. Note that an engine already exists in python, so using pyUNO could be a good idea
  

These tools creation and how they can be packaged as Extensions can be discussed on users@extensions.openoffice.org. The core part, the api use and help remains on dev@api.openoffce.org mailing list

I propose you to visit our enriched Wiki (some part are even being translated but any mediawiki tool pointer for multilingual support would be great) and join us on dev@extensions.openoffice.org to build the ecosystem, users@extensions.openoffice.org to start building extensions and #ooo-ext freenode IRC channel for a live chat

A second blog

Just to let you know: I have decided to split this blog in two distinct blogs for more clarity, ecm, java and cps related things will remain here, while python related things will now be written in a secondary blog: Carpet Python.

How to transform an Open Source ECM project into a Success ?

Euriware and Nuxeo give you a good reason to wake up early in the morning ! We'll have the great pleasure to welcome you next thursday (10/19/2006) from 8 to 11 AM for an information breakfast, to share our experience about Open Source ECM projects and document management.

This meeting will give you the keys to transform your Open Source ECM project into a real success and to optimize the use of Open Source softwares.

I'll be pleased to present Nuxeo's document management products (including a live demonstration) and to discuss with you about the advantages of Open source ECM solutions.

And last but not least... As a cherry on top of the cake, Areva NC will be there to make a testimonial about their own success based on Nuxeo's solutions.
