I want to scrape data periodically from a website and save it to a database that's should be readable by everybody. I thought about using a Google Docs Spreadsheet but the overall API management (especially the authorization) seems to be not suited to my needs. Do you know of any alternatives?
A quick an easy way to provide open access to your scraped data would be pushing it to GitHub or another easily accessible online repo in a text format (CSV/TSV or JSON if it's less structured -- this would also allow you to add timestamps for when data was scraped) and update it automatically. Without an explicit license to publish the data it may not be open, legally-speaking, so I would advise including any license information published on the source site as well as asking for the data and/or permission from the publishing organization. Even if they say no or ignore you, you've done your homework and may learn something important (and they can't say "yes" if you don't ask).
