Plone is a Software Plone is an Software API
Plone is a Community Plone is a Foundation

18.
Plone Core is an API
→ but there are more than one API:
plone.api, plone.restapi and Plone-UI
→ none is complete
Every Plone Company has a
different point of view of competitors
→ different focus of their product

19.
What is “Plone “ now?
● “The mature open-source Python CMS”
● “Plone is the community”
● Foundation Viewpoint API contract
○ Plone CMS ➤ Security
○ Zope ➤ Flexibility
○ Guillotina ➤ Extensibility
○ Volto ➤ User Experience
● Community Viewpoint
○ Sprints
○ Conferences
○ Add-ons
Plone as the API contract

20.
Implementations may change
overtime, values don’t
What do customers and
users want nowadays?

21.
Plone has evolved from being an
standalone product to be a contract,
the knowledge and wisdom that we the Plone community,
achieved during the last 20 years
building a world class enterprise CMS

○ Cognitive Overhead
○ Fewer Content Types
○ Composite Pages

API Problem
Pareto principle → 80/20 rule
● Define the API → Functionality
● Reinventing the wheel
● Never 100 % Feature compatible
(undocumented features, no API definition for feature)
● Depreciation of features

44.
A complex system that works is invariably
found to have evolved from a simple system
that worked. The inverse proposition also
appears to be true: A complex system designed
from scratch never works and cannot be made
to work. You have to start over, beginning with
a working simple system.
