<h2 id="data-feed-formats">Data feed formats</h2> <ul><li><a href="/facts/RSS/WBAWrkdj">RSS</a> 1.0, 2.0</li> <li><a href="/facts/Atom_feed/69syB8dH">Atom feed</a></li> <li><a href="/facts/RDF_feed/WMufyukm">RDF feed</a></li> <li><a href="/facts/Comma-separated_values/dv1pSR1r">Comma-separated values</a> (CSV)</li> <li><a href="/facts/JSON/bs1rUAhd">JSON</a></li> <li><a href="/facts/XML/clNgUfWk">XML</a></li></ul> <h2 id="emerging-semantic-data-feed">Emerging semantic data feed</h2> <p>The Web is evolving into a web of data or <a href="/facts/Semantic_Web/NFHo9dB7">Semantic Web</a>. Data will be encoded by Semantic Web languages like <a href="/facts/Resource_Description_Framework/WMufyukm">RDF</a> or <a href="/facts/Web_Ontology_Language/jkr0IGn8">OWL</a> according to many experts' visions. So, it is not difficult to envision data feeds 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 other computers. </p> <h2 id="csv-data-feed-and-affiliate-marketing">CSV data feed and affiliate marketing</h2> <p><a href="/facts/Comma-separated_values/dv1pSR1r">CSV</a> (Comma-separated values) data feeds are mostly being used within <a href="/facts/Affiliate_marketing/zXF81bUX">affiliate marketing</a>. Affiliate or so called publisher websites use the CSV file to load product information from online stores. This way it is a lot easier to load thousands of products to the website. CSV is not like <a href="/facts/XML/clNgUfWk">XML</a> and is not as semantic but it does have a good basic structure. This file format can easily be created and loaded with any spreadsheet program like <a href="/facts/Microsoft_Excel/Ezal6G75">Excel</a>. </p> <h2 id="see-also">See also</h2> <ul><li><a href="/facts/Semantic_publishing/cML1yAN0">Semantic publishing</a></li></ul> <h2 id="external-links">External links</h2> <ul><li><a href="http://validator.w3.org/feed/">W3C Feed validation</a></li> <li><a href="http://www.w3.org/RDF/Validator/">W3C RDF validation</a></li></ul> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>"Data Feeds".
