You can run the inverted constraint on the database to list the problematic rows. And save hours of debugging to actually understand what is going on.

The development team is pleased to announce the 3.0.0 release of CubicWeb, also
know as ShowTime.

What is CubicWeb?
-----------------

With CubicWeb, the Semantic Web is a construction game!

CubicWeb_ is a semantic web application framework, licensed under the LGPL, that
empowers developers to efficiently build web applications by reusing components
(called cubes) and following the well known object-oriented design principles.

Its main features are:

    * an engine driven by the explicit data model of the application,
    * a query language named RQL similar to W3C’s SPARQL,
    * a selection+view mechanism for semi-automatic XHTML/XML/JSON/text generation,
    * a library of reusable components (data model and views) that fulfill common needs,
    * the power and flexibility of the Python programming language,
    * the reliability of SQL databases, LDAP directories, Subversion and Mercurial for storage backends.

Being built since 2000 by an R&D project still going on today, supporting
100,000s of daily visits at some production sites, CubicWeb is a proven end to
end solution for semantic web application development that promotes quality,
reusability and efficiency.

The unbeliever will read the quick overview_ of CubicWeb.

The hacker will join development at the forge_.

The impatient will move right away to installation_ and set-up of a CubicWeb
environment.
