View source for D45 General Platform Maintenance

= Overview =
The Rodin platform versions concerned by this deliverable are:
* 2.1(08.02.2011),
* 2.2(01.06.2011),
* 2.2.2(01.08.2011),
* 2.3(04.10.2011),
* 2.4(31.01.2011),
* 2.5(30.04.2011).
This year, the maintenance carried on fixing identified bugs, although an emphasis has been put on correcting usability issues. Indeed, during the meeting in Nice, the WP9 members agreed to refocus on the needed tasks to address some specific bugs and issues reported by DEPLOY partners, and wished resolved by the end of DEPLOY. Thus, no new features were implemented but those appearing in the description of work. The tasks to be performed by the WP9 members were then scheduled, prioritized and regularly updated during the WP9 bi-weekly meetings. The updates allowed to capture and integrate rapidly some minor changes to enhance the usability of the platform which were required by the DEPLOY partners. The following paragraphs will give an overview of the the work that has been performed concerning maintenance on the existing platform components (i.e. core platform and plug-ins).

See the Release Notes<ref name="documentation">http://wiki.event-b.org/index.php/D32_General_Platform_Maintenance#Available_Documentation</ref> and the SourceForge<ref name=documentation>http://wiki.event-b.org/index.php/D45_General_Platform_Maintenance#Available_Documentation</ref> databases (bugs and feature requests) for details about the previous and upcoming releases of the Rodin platform.

* Core platform maintenance (Thomas Muller)
The maintenance done to overcome Rodin scalability weaknesses and enhance the proving experience will be detailed in a separate chapter. However, some features initially planned and those further added and prioritized are worth to mention and will be details in the Motivations section concerning platform maintenance.

* {{TODO}} An overview of the contribution about Mathematical extensions / Theory Plug-in (Issam Maamria)

* {{TODO}} An overview of the contribution about Plug-in Incompatibilities (All partners) 

* {{TODO}} An overview of the contribution about Modularisation (Alexei Illiasov)

* {{TODO}} An overview of the contribution about Decomposition (Renato Silva)

* {{TODO}} An overview of the contribution about Team-based Development (Colin Snook, Vitaly Savicks)

= Motivations =
The tasks to solve the issues faced by the DEPLOY partners have been listed and being assigned to groups according to their priority. A high priority means a high need in the outcome of a given task. The group 1 has the highest priority, the group 2 has an intermediate priority, and the group 3 has the lowest priority. The group 4 concerns topics that could not be ressourced during the lifetime of DEPLOY.The prover integrity item although not being directly covered, has been partially addressed thanks to Isabelle and SMT integration. Unfortunately, the originally planned export of full proofs and integrity check is beyond the scope of DEPLOY.

== Platform maintenance ==
The platform maintenance, as it can be deduced from the above tables in section [[#Motivations | Motivations]], mainly concerned stability and performance improvement. These topics will be discussed and detailed in a separate chapter about scalability improvements.<br>
However, other prioritary improvements were added. These improvements or came from DEPLOY partners specific needs, or were corresponding to previously identified needs(listed in the D32 - Model Construction tools & Analysis III Deliverable).

== Platform maintenance ==
By the end of the project, there are :
* xx bugs reported and open. All with a priority lower or equal to 5.
* xx feature requests expressed and still open.
The necessary tasks have been performed in the last year of DEPLOY to make the platform usable and stable in an industrial context.
