I have a lot of respect for Google. They are the best search engine I know of. They have the best Usenet archive I know of. They use some of what I consider to be the coolest technologies around. And they let you access their data as XML, making them one of the few "Web services" that actually work. "Google XML API" [1] gives you access to the same data that are available through the HTML interface, with the important difference that non-interactive user agents are allowed and expected [2] to use this service. As with the HTML interface, the service is free to users with the minor difference that users of the XML API are limited to 1000 queries per day and 1000 results per query [3] -- neither of which seems unreasonable to me; I don't think I ever came anywhere near that number using the HTML interface. To enforce these limits, a service needs to discriminate between users -- and indeed an XML API query must include a license key assigned to a user when he or she signs up for the service. Google's terms of use prohibit acquiring more than one key per (human) user[4]; to enforce this, Google tie codes to email addresses. Which leads to the observation that with the XML API, every Google query is linked directly and unambiguously to user identity, whereas an HTML query is only linked to an IP address [5]. Do I care if Google know I searched for "offshore exploration oil"? No. Do I trust them not to release that fact to, say, Inland Revenue or IRS? Yes. Do I like that fact sitting in a database somewhere[6] FFU? No. Ari. [1] http://www.google.com/apis/ [2] http://www.google.com/apis/api_faq.html#gen6 [3] http://www.google.com/apis/api_faq.html#gen7 [4] http://www.google.com/apis/api_faq.html#gen10 [5] Unlike an IP address which may or may not give hints to user identity, a license key is an assertion by the user that she is who she claims to be. Using another's id is a violation of the terms of service. [6] And being XML, the data are likely to outlive the application (TM)
