When I was browsing the open data tables in the YQL console at:
...I noticed that the yahoo.finance.* tables are designated as "Community Tables."
Is there a reason for this designation?
What are the practical implications of being a Community Table?
Is yahoo.finance.* still suitable for commercial use?
yahoo.finance is not suitable for commercial use.
Please note that data available on the Yahoo! network (ex. Finance, Weather) is not approved for commercial usage via YQL, unless mentioned otherwise in the Terms of Service.
The yahoo.finance tables are not official Yahoo YQL tables. They were created by 3rd parties or were intended as examples. They are also rate limited by the finance site or are occasionally blocked.
