oEmbed is a newly released spec from Cal Henderson (of Flickr), Mike Malone and Leah Culver (of Pownce), and Richard Crowley (of OpenDNS) that allows web sites to quickly and easily embed media when a user posts a link directly to that resource. oEmbed is an open format which standardizes the process of embedding photos, videos, links, or other media and circumvents the media provider's API (or the need for screen scraping if they don't offer one). It works by turning a link to, say, a photo or video into XML or JSON that tells the user how to embed that media.

Here's a great video presentation I found about the Semantic Web; I transcripted all the main parts here below. Text transcription: The Internet as we know it today is in an extending success: more than 1.300.000.000 (1,3 billions) people are connected to the Web across the globe. In 2006, 161 EB of informations were created or replicated world wide. IDC estimates the increase over 6 times this metric by 2010 - to 988 EB, or to 1 ZB a year.......

oEmbed is a format for allowing an embedded representation of a URL on third party sites. The simple API allows a website to display embedded content (such as photos or videos) when a user posts a link to that resource, without having to parse the resource directly.

Two days ago Stephen Wolfram gave an early preview of his "computational knowledge engine" Wolfram Alpha at a talk at Harvard University. The video of the whole presentation (1h 45min long) is here above, while down below you can find some highlights I transcripted from his speech.

Looking at Michael Pick's video DataPortability - Connect, Control, Share, Remix and on the dataportability.com home page, I saw that RDF was included in a brief list of standards involved, and something occurred to me about the value of RDF in attempts to share data across applications such as social networking sites-in particular, why it's better than XML for this.
