What is Knowledge? Defined as (i) expertise, and skills acquired by a person through experience or education; the theoretical or practical understanding of a subject, (ii) what is known in a particular field or in total; fact and information or (iii) awareness or familiarity gained by experience of a fact or situation. Knowledge, and skills are different but related sorts of things. Knowledge has to do with what you know; what you are aware of and what you understand about how things work and how things fit together. You may have come by knowledge first hand through life experience, or you could have taken it from books, websites and other means of recording. Skill or ability, on the other hand describes your ability to influence things; to take what you know and apply it so as to cause a real effect to occur.
Knowledge Vs Information: Knowledge is not just information. It must be usefully available to the system, though that system may not be conscious. The system should be dynamic and self-organizing (unlike a mere book on its own). The knowledge must constitute some sort of representation of "the outside world", or ways of dealing with it (directly or indirectly). There must be some way for the system to access this information quickly enough for it to be useful. Knowing something intellectually is a very different thing than knowing how to make practical use of knowledge.
Knowledge Gap: In the service sector the spread of knowledge remains confined to an individual or a company the knowledge workers interacts with. The concept of recycling and reusing knowledge and releasing its full potential to the masses remains largely untapped. It is because the current systems operate in closed arena, providing access to knowledge only to those who interact with these knowledge providers directly or indirectly.
Why is access to knowledge important?
- Increasing integration of every individual into a global trade system
- Information knowledge based economy
- Rise of networked information society
- Gradual ascendance of human rights, the human dignity; development as freedom
Access to Knowledge is therefore central to human development as right to freedom and justice is. 
There should not be a barrier for anyone to acquire either the knowledge to become a professionally trained service person or the opportunity to deliver the professional knowledge regardless of geographical boundaries and the knowledge once delivered should not need to be recreated and the knowledge once discovered should be available for sharing; when we have an infrastructure like the internet.
An open and transparent self-organizing system where knowledge can be pooled, sold, traded, distributed, recycled, reused by many and created by many is practically non-existent. In recent years a lot of new initiatives (Wikipedia, YouTube, Scribd, etc.) on moving towards open and self organizing systems (where knowledge can be pooled, collaborated on, shared and distributed in a self organizing way) have taken place on the internet. What we now call Web 2.0 companies. However most of these initiatives still operate as a free source for distributing knowledge and do not operate like marketplaces.
Knowledge Marketplace as a Knowledge System
SPINACT™ Knowledge Marketplace not only organizes information producers as well as the knowledge systems, it is also a platform where Knowledge can be freely traded across the board as a commodity, making it universally accessible, but also the viability of that access possible through driving a Knowledge based economy.
