The New Curated Data functions are interesting. But I doubt that the data is solely coming from Yahoo, if at all. I could see with the use of Mathematica and a small staff data mining the internet for all this data. For example; the FinancialData name-related properties is not unique but admirable to say the least. The "CIK","Company","CUSIP","Exchange","ISIN","Name","StandardName","Symbol" Otherwise normalizing a company is very important because the data or the free data is spread through out the internet and is constanly changing. This helps understand what company is the subject. However, Wolfram's choice of using the exchange codes is lacking, because from one day to the next this could change; however, this is what everyone in business world speaks. For US companies there is a relationship between the ISIN and the CUSIP. However, CUSIP is propriatery, and they have strict rules about dissemination of their data. The CIK is and EDGAR (SEC) assigned number, but for all purposes it is freely availble data. Just this combination of properties is hard to maintain. The company related information "Sector","SICCode","Website" can be found at NASDAQ but NASDAQ states that this information is what was filed with the SEC. This blog link hints at the development of this and other kinds of data http://blog.wolfram.com/2007/05/computable_data_functions.html. I find all the curated data a good effort. I hope that there will be more of it. I think Wolfram can add data such as: tidal (Oceanographic data); Weather (Atmospheric) [hey, when there's nothing we can compute in common we can compute the weather]; browsing the functions.wolfram.com site within the help guide (why escape to a web browser).
