This structure is typical of charities, clubs, trade bodies and social enterprises. Its company number 05133759 shows it was registered in England and Wales, so its records are kept by Companies House in Cardiff. It has been on the register for 22 years and 5 months.

What OPEN KNOWLEDGE FOUNDATION does

On the public register, OPEN KNOWLEDGE FOUNDATION lists its activity using the UK Standard Industrial Classification (SIC 2007): activities of other membership organizations n.e.c. (94990). This places it in the other service activities section of the economy. SIC codes describe what a company says it does; they are not a licence and are not checked by Companies House.
