The document discusses Plone, a Python-based content management system (CMS) that allows users to manage and edit content through workflows, with various installation options and a focus on scalability. It highlights the advantages of Python's dynamic nature and the use of ZODB for object storage, as well as the ability to extend Plone with add-ons and the evolution of content types. Additionally, it touches on the challenges and considerations for using ZODB and positioning Plone as an enterprise-grade solution.

1. Building Them with Frameworks
2. Running Them with CMSes

4. Existing Frameworks

5. Plone = Python based CMS
CMS = Contents in Database
Added/Edited by User/Group
Managed via Workflow
Searchable with Index/Catalog

6. Installation Options
1.Unified Installer
2./usr/bin/python
3.VirtualEnv

7. Content ID = URL
http://localhost:8080/mysite
http://mysite.com/my_folder/my_item
http://mysite.com/my_folder/my_item/view
http://mysite.com/my_item/edit
http://mysite.com/manage

9. Undo, Transaction, Versioning
Python’s dynamic nature allows
developers to quickly develop applications,
avoiding the compile cycle and static
typing declarations required by other
languages. The ZODB offers a similar
benefit: developers who use the ZODB can
store their objects transparently without
any cumbersome mapping of objets to
relational database tables.

17. Python Building Blocks
Python Packages are distributed as Eggs
Python Package Index
http://pypi.python.org/
Example:
easy_install docutils
pip docutils

18. Extend Plone with Add-ons
Plone Addon (Product) =~ Python Package (Egg)

19. How Plone Add-ons Work
zc.buildout helps to install addons

20. CMS = Forms in Database
Form = Content Type

21. Form = CMS Core
Content Type = Schema
= Fields + Widgets

22. From Archetypes To Dexterity
Improved Content Type Building Framework

23. Dexterity Behaviors
Reusable components that can be
enabled on a per-type basis
through enumeration in the FTI.
