Having a single point of failure like this certainly won't help your fundraising efforts. If you're going to take the legal risk, why not bootstrap? That way you can put the money in your pocket as you go along and if the site does get shut down, at least you've extracted the profits along the way.
Also, most databases that you can scrape will contain sentinels to tip off the database owner that you've scraped their content. The sentinels are typically bogus records that are hard to spot, including them in your output will do a good job of proving that you ripped the data.
If you're just going to regurgitate the data you would have to have a better excuse than 'making it more accessible and useable', you could offer your services to the current owner of the data. If they abandon the data that's a different story, but it sounds to me like they are not.
Another option is to license the data, simply contact them to ask if they have licensing options, this is the usual way to go about this.
Scraping is also a heavy drain on the resources of the company whose data you intend to harvest, this means that if they sue you successfully for breach of copyright that they have a fairly clear path to claiming damages.
good luck!
ps: if you have a corporate lawyer that would be a good spot to ask for advice.
This depends on the jurisdiction. I believe the EU has a specific database copyright, while the US explicitly doesn't recognize one. A database may be copyrightable under normal copyright law in the US, but only if it's sufficiently creative (e.g. a database containing nothing but a mechanical listing of stock closing prices wouldn't be copyrightable).
But annotation and such do add value, as does the original collection of data.
Am I allowed to scrape information from their websites and use it to populate my system? Isn't that effectively what google does?
Is there a limit to what is considered acceptable/not acceptable? E.g., is it OK to scrape for email addresses that they publish on their site, but not for their part numbers?
Thanks!
I used to make money by doing this and selling the results to financial research firms. But, I didn't make any of the details of what I was doing public.
