Data feed
From Wikipedia, the free encyclopedia
Data feed is a mechanism for data users to receive updated data from data sources. It is commonly used by real-time applications in point-to-point settings as well as on the world-wide web. The latter is also called web feed. News feed is a popular form of web feed. RSS feed makes dissemination of blogs easy. Product feeds play increasingly important role in e-commerce and internet marketing. Data feed usually requires structured data. But, at the present time unstructured data, e.g. a web html page, dominate the web. As a result, data feed has huge potential to make bigger impact on the web in the future.

[edit] Emerging semantic data feed
The web is evolving into a web of data or semantic web. Data will be encoded by semantic web language like RDF or OWL according to many experts' visions. So, it is not difficult to envision data feed will be also in the form of RDF or OWL. A big advantage of providing semantic data feeds, i.e. feeding data in semantic web standards, is that the data can then be readily consumed and reused by more computers. Examples of semantic data feed are available on the free Ufeed online service. Ufeed allows users to create feeds in RDF format for various types of data, which include product information, news, events, job openings and studies.
