Hi, i wonder if it is legal to build such a website that aggregates RSS feeds from many websites to one, like http://www.wopular.com/ for example, it has text and photos from other websites on its own content pages, of course linking to the appropriate owners(source websites/newspapers). Is that legal to run such a website and put own ads here ( that would also mean it is a commercial website)? What do you think?
it's legal as long as you only post a snippet of the post and in order to read the rest you have to click on the source link but if you just full on take the whole article thats something else
Yes, it's legal. The RSS only gives you one or two sentences. You can't copy the whole article if you find something of value (out of RSS) to your site and you need to place a link back.
now i want to be sure about any legal aspects of business, after having some attorney issues previously thanks DP~!
If you want to be sure it's legal, ask the author or copyright holder permission to use the content. If you are interested in RSS feeds from commercial web sites, they often explicitly state whether you can reuse the content. For example, the information for Google News RSS feeds says: Advertising would like make your site be considered to be "commercial", so it's probably a bad idea to use Google news feeds for your site. There are similar terms for the NY Times: http://www.nytimes.com/services/xml/rss/index.html Non-commercial use is allowed with attribution. That is probably why there is no advertising on the Wopular site you linked to. And despite what electrojohn1 said, be aware that some RSS feeds actually provide full posts, so do some research before putting a feed on your site.
damn, i see the point but what if i only grab from every feed only two first senteces, providing the source heading? that's just like big Google indexes first sentences of content on bilions of web pages without asking anyone about it, and after all it dislpays its ads on the search results?
I think it's a gray area. As far as I know, the Google news RSS feed, for example, only includes the first sentence anyway. Maybe you could just include the headline and link to the article.
