Nuxeo Studio 2.0 available

without comments

We have made available earlier this week version 2.0 of Nuxeo Studio, the configuration and customization environment for content applications based on the open source Nuxeo EP platform.

Here is the announcement

Nuxeo Studio 2.0 brings new important features, such as content views (which were introduced in Nuxeo EP 5.4 last november) configuration, widget configuration, user groups management, content transformation, as well as usability improvement thanks to the feedback of our users.

See this page for more in-depth coverage of what’s new in Nuxeo Studio 2.0

Since Nuxeo Studio is a graphical tool, we thought it would be useful to produce a few screencasts to show how it’s used in real life:

If you’ve got questions, there is a space in this Forum dedicated to discussing Nuxeo Studio:

Or join the upcoming webinar about Nuxeo Studio 2.0 on Feb. 9.

Slides and video from my “Mobile ECM applications with Appcelerator and PhoneGap” talk last week

without comments

Last Thursday I spoke at the JavaScript for Enterprise Applications (JSE2011) conference (that I also co-organised with my friend Jean-Paul Smets from Nexedi/ERP5/TioLive).

I wanted to talk about the soon to be released mobile ECM clients we are building for the Nuxeo platform, which I’m going to write a longer blog post soon.

Here are my slides:

Mobile ECM with JavaScript – JSE 2011

And a video:

Overall it was a really good conference, with a lot of material covered over the course of the afternoon and a room packed full of interested and interesting people.

Agile@Nuxeo: How we do work estimates

with 2 comments

I’m Benjamin Jalon, a software engineer at Nuxeo and in charge of our agile development practices. One of my missions is to keep Nuxeo’s engineering teams nimble and efficient by continually pushing them to improve our development processes and methodologies. This blog will highlight how we strive to meet these challenges and offer guidance to our clients and integrators so they can do the same. As you might know, at Nuxeo like at many quality software houses, we use techniques from Japan and a strange term from rugby.

Work Load Estimate, The Nuxeo Way

How many times in my working life have I heard a developer explaining to his wife that he will finish in ten minutes? How many times have I told my own wife that she can start to cook because I will be at home soon? Enough times to know that developers’ wives eat alone and burn …

Nuxeo DAM 1.2 Release Candidate 2

with 2 comments

It’s a new year and we have a new Release Candidate for you! The Nuxeo DAM 1.2 Release Candidate 2 contains corrections and improvements over the RC1 version. See below for the list of issues that were resolved.

For developers or community members who want to try this new pre-release version, you can download Nuxeo DAM 1.2 RC2 and read the Nuxeo DAM documentation.

If you have any issues or questions, check our JIRA Issue Tracker
and the Nuxeo DAM Forum.

For those interested in playing with the easy installation of Nuxeo Marketplace packages via the Nuxeo Admin tool, there is a new package on the Nuxeo Marketplace called Nuxeo DAM PDF Export. It exports a selected list of images into a single PDF file. The first page is a cover page, and each subsequent page contains the filename as the title and the image itself as …

Why Nuxeo Dropped JCR

with 5 comments

There have been questions about JCR vs CMIS recently (Is JCR Dead?), and I thought I'd expand a bit on why we at Nuxeo decided to drop support for JCR.

Nuxeo used JCR in the past with great success; we've been on the JSR-170 and JSR-283 Expert Group and it is a very nice spec. Several versions of our Nuxeo EP framework used Jackrabbit as a content store.

However for some time we've decided to not rely on it solely, and for more than two years, since Nuxeo 5.1.6, we've had an alternative storage engine, the Nuxeo Visible Content Store (VCS) ( Since Nuxeo 5.4 VCS is the only content store, and it's optimized for all the things we require of it.

The reason why we wanted an alternative storage, and why we now rely exclusively on it instead of maintaining costly compatibility with a second storage …

Mining Wikipedia with Hadoop and Pig for Natural Language Processing

The context: semantic knowledge extraction from unstructured text

In a previous post we introduced fise an open source semantic engine
now being incubated at the ASF under the new name: Apache
. Here is a 4 minute demo that
explains how such a semantic engine can be used by a document management system
such as Nuxeo DM to tag documents with entities instead of potentially ambiguous words:

The problem with the current implementation, which is based on
OpenNLP, is the lack of readily
available statistical models for Named Entity Recognition in languages such as French. Furthermore, the existing models are restricted to the detection of few entity
classes (right now the English models can detect people, place and organization names).

To build such a model, developers have to teach or train the system
by applying a machine learning algorithm on an annotated corpus of data.
It is very …

Several updates to the Nuxeo community sites

without comments

We’ve been busy during the holidays updating the different Nuxeo community websites:

  • The forum (as I already announced) has moved to a new forum engine that should be more robust that the previous one:

  • The documentation site has a new home page with, we hope, a clearer roadmap to navigate through the documentation:

    We’ve also have written a new “beginner’s page” (aka: “everything you need to know about Nuxeo in 5 minutes”):

    And a “business FAQ” that should be helpful when responding to a RFP:

    We’re still busy updating other parts of the documentation.

  • There is now a “home page” that aggregates info from the community sites (forum, blogs and documentation), and also provides the key links for newcomers.

  • You can also subscribe to the RSS feed that provides updates similar to the “wall” provided by (with a
