I would also see that there is a strong case to say that it is aggregation. Something that would help is redirecting users to the original source content whenever you are referencing it within your search.
But it’s a big mindset chnage (one that will benefit the whole country) but it’s slow.
I think the “push for public policy improvements” angle if genuine will get you a lot more respect and kudos when things get sticky. Good luck
No-one has figured out how to make money off open source (while sticking to the basic principles. Jeff Bezos makes a fortune off of it)
Most people who open source their code that I have known and still wanted to be paid / recognised for their effort have always been disappointed
Can I suggest you mentally put the work you have done to date into a box marked “the past”, open the data, start yourself as part of the community trying to make government code and data open, and sell your skills - the old “consultancy paying the bills” approach
Trying to make cash off public data will just confuse the message, and start to build resentment. Make a clean and clear statement, Sell your services on top. Expand to other forms of data scraping in government.
It’s a tough road - good luck
A few weeks ago, I'd have said the SaaS product is the play, but now I'm not so sure. Cheers for taking the time.
