Event-B and Rodin Documentation Wiki

http://wiki.event-b.org/index.php/Main_Page

This is the documentation wiki for the Event-b.org site providing documentation for users and developers of the Rodin toolset.
Event-B is a formal method for system-level modelling and analysis. Key features of Event-B are the use of set theory as a modelling notation, the use of refinement to represent systems at different abstraction levels and the use of mathematical proof to verify consistency between refinement levels.
The Rodin Platform is an Eclipse-based IDE for Event-B that provides effective support for refinement and mathematical proof. The platform is open source, contributes to the Eclipse framework and is further extendable with plugins.

Vendredi 5 juin : La petite géante devrait se réveiller vers 11h place Viarme et le scaphandrier géant devrait émerger du bassin Saint-Félix vers 13h30 au niveau du pont Tbilissi. Ils parcourront ensuite les rues de Nantes le vendredi après-midi (chacun de leur côté ou ensemble ?) : le scaphandrier devrait atteindre la place de la petite Hollande vers 15h avant de se reposer. Le spectacle reprendra ensuite vers 19h.

Samedi 6 juin : Un réveil est prévu samedi 6 juin à partir de 10 h au niveau du château (à proximité des loups en liberté dans les douves).

Dimanche 7 juin : Ils embarqueront à bord d’un chaland vers 11h à proximité du pont Anne de Bretagne (et donc du grand éléphant :-). Le bel équipage naviguera en direction de Saint-Nazaire via Indre, Couëron, Le Pellerin, Frossay et Paimboeuf. L’arrivée à St-Nazaire est prévue vers 17 h et la fin du spectacle, en début de soirée vers 20h/20h30.

June 7-2009, Nantes, Royal de Luxe

Du 5 au 7 juin 2009, Royal de Luxe revient avec un nouveau spectacle de géants dans le cadre de la biennale d'art contemporain Estuaire 2009.

"

Royal de Luxe are an extraordinary European street theatre company, renowned on three continents but hardly known in Britain.

The director Jean Luc Courcoult founded the company in 1979, and they have performed all over the world ever since.

The company has visited countries all over Europe as well as Korea, China, Vietnam, Chile and Africa. Some of their most celebrated shows – including La véritable histoire de France, Roman photo tournage and Le péplum have been revived many times and performed in front of thousands of spectators. They spent six months in Africa and three in China

In the past dozen years, they have created a series of spectacular shows involving giant figures as big as 11 or 12 metres high. Shows are simple – the animal or giant arrives in town and lives its life, going about its business for a few days. Extraordinary interactions take place between passers-by and the performance; residents become enchanted with the activities of these miraculous beings and begin to follow their every move. By the end of the performance, huge crowds gather daily to watch the latest episode in the life of the visiting creature. The Sultan’s Elephant is the fifth in the series of giant pieces, the others being Le Géant tombé du ciel, Le géant tombé du ciel: dernier voyage, Retour d'Afrique and Les Chasseurs de girafes.

La visite du sultan des Indes sur son éléphant à voyager dans le temps was first performed in Nantes from May 19th to 22nd and in Amiens from June 16th to 19th 2005, on the occasion of the centenary of Jules Verne's death. This production was commissioned by the cities of Nantes and Amiens and has received a special grant from the Ministry of Culture and Communication."

Fête d’ouverture
Royal de Luxe
“La géante du Titanic et le scaphandrier”*

Vendredi 5, samedi 6 et dimanche 7 juin

Estuaire 2009 signe le retour d’une nouvelle création de la compagnie de théâtre de rue Royal de Luxe. Pendant trois jours, Jean-Luc Courcoult, auteur et metteur en scène, nous fait partager de nouveaux moments de vie du Géant et de sa nièce, la Petite Géante.
Et comme la Loire est le personnage principal de notre aventure estuarienne, préparez-vous à de nombreuses surprises… Notamment le dimanche 7 juin : prévoyez pique-nique, vélos et canoës pour nous accompagner sur les bords du fleuve !

“En 1912 coulait le Titanic. Mais ce que l’histoire n’a pas retenu c’est qu’il transportait en secret une géante de 10 m de hauteur, capturée dans la Terre des glaces, à l’époque gouvernée par le Danemark. L’Islande, faite de volcans, abritait alors certains géants fort occupés à moduler le paysage pour en faire une terre habitable. L’un d’entre eux, ou plutôt l’une d’entre elles, avait pour tâche de faire apparaître d’immenses geysers destinés à correspondre d’une montagne à l’autre : un peu comme les Indiens d’Amérique avec leurs nuages de fumée, ou l’invention du sémaphore à la Révolution française.

Des corsaires anglais, au solde de sa Majesté, capturèrent la géante. Elle fut embarquée clandestinement dans une cale du Titanic afin d’être exhibée dans le Nouveau Monde et démontrer ainsi la suprématie du Royaume-Uni. Comme chacun sait, le navire déchiré par un iceberg venant du Nord de l’Islande, sombra et par le fait notre géante avec. Mais comme tout passager du bâtiment notre géante avait de la famille : un frère nommé “le géant” et une fille appelée “petite géante”. Pendant la capture de sa mère, la petite géante s’enfuit sur un bateau. Le géant, occupé à scier des icebergs constata à son retour la disparition de ses amis. Durant de longues années, il parcourut le fond des océans et finit par retrouver l’épave. Il enterra sa sœur au fond de la mer et découvrit la malle-poste du paquebot gisant à quelques centaines de mètres de la carcasse brisée. Alors il décida de distribuer le courrier du vaisseau mythologique et de rejoindre sa nièce : la petite géante.”

Formal Methods Wiki

I have created a new Formal Methods Wiki under
http://formalmethods.wikia.com . This includes new versions of the Virtual Library forma methods pages, that are unfortunately now offline due to a disk error.
These pages are now editable by anyone, so I am hoping that members of the formal methods community will improve these and bring them up
to date, as well as adding new formal methods-related material.

The facility is based on Wikia, established by Jimmy Wales who also founded Wikipedia. The underlying wiki software is MediaWiki, the same as Wikipedia.
I would encourage all members of the formal methods community to contribute any information related to formal methods to the wiki, including hyperlinks
to further information. It is best although not essential to register with the site if you plan to do more that a small number of edits. This is very
simple (similar to Wikipedia). If you are unsure of the MediaWiki markup, it is easiest to press the "Edit" button on a page that is similar to one you
wish to create, copy the text, paste it into the new page, and edit it as required.

I hope this facility is helpful. Please don't worry about making mistakes since everything is easily correctable on a wiki; I will keep an eye on new
entries and edit further as needed. I look forward to your active participation on the site!

"Extending B without changing it"

J.R. Abrial, Extending B without changing it (for developing distributed systems)
file:///U:/public_html/ConfZetBdeNantes/Abrial.htm

Atelier B or Atelier B ?

What's in a name?

http://atelier-b.blogspot.com/

Une introduction à la méthode B

http://www.sciences.univ-nantes.fr/info/perso/permanents/habrias/methodb.html

and some pages on B

a shallow embedding of B set-theory in Coq

A message of Samuel Colin
Hi list,
for the past months I spent some effort upon the development of a shallow embedding of B set-theory in Coq[1]. The goal was two-fold:
- Validate, by implementing them, theorems of the B-Book, the "bible" of the B method[2]
- Have a prover for B based on what is described in the B-Book[3]

So, firstly, some links:

https://gna.org/projects/brillant

where this project is hosted, in a "bicoax" subdirectory of the Subversion trunk.

http://download.gna.org/brillant/snapshots/ for tarballs (you want the most recent one)
It should compile on a Linux platform with coq 8.2 (available as of very recently) and make, see the INSTALL file.

http://download.gna.org/brillant/snapshots/bicoax-html/
and
http://download.gna.org/brillant/snapshots/bicoax-html/toc.html

for the documentation generated by coqdoc (most of the comments refer to the place in the BBook of the corresponding theorem/definition).

In a nutshell and very broadly, I make this announce because it has entered a usable state, as showed by the Bmisc.v file of the project, containing two examples of small B projects whose all proof obligations are proved in BiCoax. BiCoax will be (and is already, in a sense) plugged back into the other tools of the BRILLANT platform so as to obtain a full toolchain for developing B projects.

What is implemented covers the first part of the B-Book: the first chapter (logical connectors), the second chapter (derived constructs, relations, functions) and half of the third chapter (mathematical constructs, up to and not including relative integers). Some constructs introduced in event-B were also added and I also put some eventB unicode notations with (hopefully) the correct priority as described by the Rodin D7 deliverable.

You can find an expanded version of this message here:
http://download.gna.org/brillant/snapshots/BiCoax-announce
with more technical details.

This message was sent to the "BForum" mailing-list and the "Coq-club" mailing list.

***Call for papers*** From Research to Teaching Formal Methods - The B Method

==================================================
***Call for papers***

Conference
From Research to Teaching Formal Methods - The B Method
TFM B'2009
8 June, 2009, Nantes, France
www.lina.univ-nantes.fr/apcb

==================================================

The first B conference took place in Nantes during November 1996
and was followed by the Montpellier, York, Grenoble, Turku,
Guilford and Besancon, and London (2008) Conferences.
During the conferences of Montpellier and Grenoble,
education sessions were held with published proceedings.
The APBC Association (International B
Conferences Steering Committee) organised meetings
in Paris and in Nantes. The
Nantes meeting was devoted to teaching. But since a
few years, there was no meeting dedicated to
teaching.
Software Engineering research must lead to put
it into practice. For that, it is
necessary to use teaching, teaching that must
conciliate the basics and the practice.
We may consider two principal arguments in favour
of teaching the B method:
First, the B method and his concepts can be
considered as having an essential pedagogical
interest even if this method is not used.
The B method is an industrial method which
reaches the industrialisation level going
from specification to programming. There
are several examples of concrete applications.
In this 2009 edition we also encourage the
submission of papers describing teaching
experiments based on other tool-equipped
formal methods that are used in industry
and that help in adopting formal methods
in curricula.
