===== TinyERP / OpenERP / Odoo =====
==== The Tool ====
  *[[http://www.odoo.com/| OpenERP S.A. "Odoo"]].
  *[[http://www.odoo-community.org/|Odoo Community Association]] ( OCA ) - "A nonprofit organization whose mission is to support the collaborative development of Odoo features and promote its widespread use".
  *[[http://www.github.com/odoo|GitHub "Odoo - Open Source Business Apps"]].
  *The legacy [[http://tinyerp.sourceforge.net/|SourceForge "TinyERP"]], [[http://www.sourceforge.net/projects/tinyerp/|SourceForge "TinyERP (Old Project, see OpenERP.COM)"]].
  *[[http://www.greenodoo.com/|GreenOdoo - Portable Odoo (formerly OpenERP)]].
    *[[http://greenopenerp.sourceforge.net/|SourceForge "GreenOdoo"]], [[http://www.sourceforge.net/projects/greenopenerp/|SourceForge "GreenOdoo. Portable Odoo (formerly OpenERP) for windows and linux x64"]].
  *The business model, as explained by experts: 
    *Patches provided by the community are just merged into the current development version, which is not intended to be used in production.
    *Patches provided by the community aren't merged into the latest stable community edition.
    *Patches provided by the community are merged into the stable commercial edition ( i.e. a special stable patched version just available if you subscribe for a commercial maintainance service ).
==== Commercial Providers ====

===== Tryton =====
==== Tryton Server ====
  *The OpenSource application server [[http://www.tryton.org/|Tryton Foundation "Tryton"]] for Python 2.7.
    *[[http://code.google.com/p/tryton/|Google Code "Tryton"]].
    *[[http://www.github.com/tryton|GitHub "tryton"]].
    *[[http://www.twitter.com/sebastianmarro|Twitter "Sebastián Marró, @sebastianmarro"]] - "Thymbra Director. Member of GNU Solidario. Board member of Tryton Foundation".
    *"Three-tier high-level general purpose application platform under the license GPL-3 written in Python and using PostgreSQL as database engine. It is the core base of a complete business solution providing modularity, scalability and security".
  *The demo server [[http://demo.tryton.org/:8000|demo.tryton.org:8000]].
  *[[http://www.twitter.com/tryton_erp|Twitter "Tryton ERP, @tryton_erp"]].
  *I was told by experts, that 
    *Patches provided by the community are both merged into some stable community editions ( the latest, some older,..) and the current development version.
    *Extending the Tryton client ( e.g. to support a new widget ) is difficult. As very few Tryton developers provided upgrades to the client in the last few years, and as the status of the client code and documentation is not perfect and especially not easy to understand and to handle, it can be expected that writing a new widget for the client might just be done by a handful of Trycon developers in the world...

==== Tips & Tricks ====
  *I experienced: A Tryton 3.4 client may just communicate with a Trytond 3.4 server, communications with a Trytond 3.5 server is refused :-(. 
  *Trytond uses the database, but the view and the models are defined in the file system. Each "object view"  is a Trython object. A Tryton client is used to display a view. Trytond is parsing the XML files and stores the infos in its database.
  *"Trytond - u mymodule anothermodule athirdmodule - d mydatabase", "Trytond - u all - d mydatabase" 
    *checks the module directory/directories for Python .py files, checks all XML files for changes and updates the database with the changes in XML files. Trytond parses all .py Python files to detect if there are new fields ( = global class variables ) in the .py Python files.
    *It makes use of the introspective Features of Python, to get variables from global classes.

  *The developers of "TinyERP" and its successors think of their software to be a framework, not a product to be used by b2b end users. They expect that other developers download from CVS system and do not ask for packages.
