CEP: source for real-time events or data feeds?

I am searching for free event sources that I can use within my java-application. I am looking for something similar to YahooFinance, where one can query a bunch of stock info and retrieve the result as csv.

Ideally, an API or a URL with some query string would be perfect.

Solution

  • How about SuperFeedr?

    You could also run some SPARQL-query on some SPARQL-Endpoint and "feed" the result back to your application. Here is a list of some endpoints (here including uptime and availability stats).

    Twitter also offers an Streaming-API, where one can listen for status changes etc.

    Another way could be to implement some HTML-crawler that extracts interesting facts from webpages, but that's probably not what you are looking for...
