The 20/20 Plan is presenting a free and open source model for a Universal Classification System that will be able to seamlessly merge information from around the world into a decentralized yet federated database system to create the public library interface of the future.

The new model composed of 20 Areas of Infrastructure and 20 Areas of Operation takes into account all industries, trades, and sciences and embodies the entire domain of human knowledge to provide a complete 20/20 vision of absolutely everything in existence.

In order to achieve this objective, the Universal Classification System is a synthesis of multiple different classification systems that are now being utilized. The 20/20 Plan takes all of the various classification systems that currently do not overlap and integrates them all into one universal system.


The 20/20 Plan fully incorporates all formal sciences and all subject areas of human knowledge contained within various library classification systems.


The Dewey Decimal System is divided into 10 categories:

You will notice that the domain of human knowledge has exponentially increased since the time when the Dewey Decimal System was first invented. The Dewey Decimal System is very much outdated and many subcategories are simply listed as “not assigned or no longer used”.


The Universal Decimal System is divided into a different grouping of 10 categories:


The Library of Congress Classification System is divided into 21 categories.


The index of the Library of Congress offers 594 Subject Categories to browse which creates an overwhelming hodgepodge of information.


Book stores tend to use a classification system provided by The Book Industry Study Group which offers the Complete BISAC Subject Headings List that is organized into 53 categories.


The primary resource for organizing collections at public libraries is the OCLC Bibliographic Formats and Standards which offers an arcane system for managing information.


The Universal Classification System takes information that is stored on the shelves in libraries and makes it applicable in the real world.

Currently, the library classification systems don’t correspond to the classification system used in occupational trades and industry.


The new model presented in The 20/20 Plan seamlessly incorporates all industries listed in the North American Industrial Classification System.


The 20/20 Plan also incorporates all professions and trades listed in the Standard Occupational Classification System.


Surprisingly, right now these two classification systems do not correlate with one another and industries are classified completely differently than occupations. One would logically assume that the occupations which compose the industries would naturally go together and should be organized accordingly but at the moment this is not the case.

This problem is effectively resolved by the new model consisting of 20 Areas of Infrastructure and 20 Areas of Operation. The 20/20 Plan synergistically integrates all existing industries and occupations into a universal classification system.


The 20/20 Model seamlessly integrates all industries, trades, formal sciences, and subject areas in the entire domain of human knowledge and introduces a new information management protocol to optimally catalogue the vast archives of multimedia content into a global library system.

As you will see, this new model is a multipurpose tool that has many useful applications.

Essentially, this Universal Classification System is the classification system of all classification systems, the taxonomy of all taxonomies, the ontology of all ontologies. This system provides the structure that can integrate all other systems. Different classification systems, taxonomies, and ontologies can all be integrated into this overarching framework.

The framework of the 20 Areas of Infrastructure and 20 Areas of Operation provides an easily navigable index for information that can be infinitely subdivided to cover an infinite number of subjects without ever having to expand beyond the 40 categories. This structure will enable people to dive into information fractally and explore a vast network of exceptional multimedia content that is seamlessly connected as a decentralized federated database system.

The Universal Classification System is the missing link that will connect the vast information networks, enabling an effective method of indexing of multimedia content to provide a free and open library system for the world.
