What is the number of entities already defined in foundation sets? (02)
Is it close to the 10,000 number, if you count the JPL set,
GoodRelations and the other domain sets already done and being augmented
Perhaps the foundation already exists. (03)
Do the people who have currently invested in ontologies get paid for
their work? At what rate? (04)
Should there be a contest or RFP issued by some government agency, to
give a "completion contract" to the organization that has the largest
existing foundation ontology so that they can complete the job? (05)
The English language has 500,000 words officially recorded and another
500,000 suspected words not officially defined. (06)
