Data: URIs can be used with Shared Media. If you're not a geek, why should you care?

In short, one possible use is: say you have some content you want to show on a prim face, but you don't want to go through the trouble of creating an HTML file and uploading it to a webserver. (Or, you don't have a server.)

You can use a data: URI tool to convert web content into a long link you can paste into Shared Media. It saves time and trouble.

Here's a simple example:

  1. In your web browser, go to The data: URI kitchen. This is an easy tool to convert HTML into a data: URI.
  2. Insert your HTML between the <body> tags. Change <p></p> to <p>This is a test!</p>
  3. Click the Generate button.
  4. Copy the full data: URI in your web browser's address bar. It should look like this: data:text/html;charset=utf-8,<!DOCTYPE HTML PUBLIC "-%2F%2FW3C%2F%2FDTD HTML 4.0%2F%2FEN">%0D%0A<html lang%3D"en">%0D%0A <head>%0D%0A <title>Test<%2Ftitle>%0D%0A <style type%3D"text%2Fcss">%0D%0A <%2Fstyle>%0D%0A <%2Fhead>%0D%0A <body>%0D%0A <p>This is a test!<%2Fp>%0D%0A <%2Fbody>%0D%0A<%2Fhtml>%0D%0A
  5. Using the steps described in Adding Shared Media to an object, paste that exact URI into Shared Media on a prim.
  6. The result should look like this:

Feel free to use more advanced code to gain familiarity. This shows several lines of styled text:

data:text/html;charset=utf-8,<!DOCTYPE HTML PUBLIC "-%2F%2FW3C%2F%2FDTD HTML 4.0%2F%2FEN">%0D%0A<html lang%3D"en">%0D%0A <head>%0D%0A <title>Test<%2Ftitle>%0D%0A <style type%3D"text%2Fcss">%0D%0A <%2Fstyle>%0D%0A <%2Fhead>%0D%0A <body>%0D%0A <p>This is a test!<%2Fp>%0D%0A%0D%0A<p><strong>But it gets fancier because we're using styled text.<%2Fstrong><%2Fp>%0D%0A%0D%0A<p><em>Feel free to play with HTML snippets and jazz it up.<%2Fem><%2Fp>%0D%0A%0D%0A<h2><font color%3D"%23ff0080"><strong>That's why we call it rich content%2C yeah%3F<%2Fstrong><%2Ffont><%2Fh2>%0D%0A%0D%0A<p><strike>This line has intentionally been struck out.<%2Fstrike><%2Fp>%0D%0A <%2Fbody>%0D%0A<%2Fhtml>%0D%0AM

This embeds a Flash video:

data:text/html;charset=utf-8,<!DOCTYPE HTML PUBLIC "-%2F%2FW3C%2F%2FDTD HTML 4.0%2F%2FEN">%0D%0A<html lang%3D"en">%0D%0A <head>%0D%0A <title>Test<%2Ftitle>%0D%0A <style type%3D"text%2Fcss">%0D%0A <%2Fstyle>%0D%0A <%2Fhead>%0D%0A <body>%0D%0A <p><object width%3D"640" height%3D"480"><param name%3D"allowfullscreen" value%3D"true" %2F><param name%3D"allowscriptaccess" value%3D"always" %2F><param name%3D"movie" value%3D"http%3A%2F%2Fvimeo.com%2Fmoogaloop.swf%3Fclip_id%3D9656041%26amp%3Bserver%3Dvimeo.com%26amp%3Bshow_title%3D0%26amp%3Bshow_byline%3D0%26amp%3Bshow_portrait%3D0%26amp%3Bcolor%3DFF0080%26amp%3Bfullscreen%3D1" %2F><embed src%3D"http%3A%2F%2Fvimeo.com%2Fmoogaloop.swf%3Fclip_id%3D9656041%26amp%3Bserver%3Dvimeo.com%26amp%3Bshow_title%3D0%26amp%3Bshow_byline%3D0%26amp%3Bshow_portrait%3D0%26amp%3Bcolor%3DFF0080%26amp%3Bfullscreen%3D1" type%3D"application%2Fx-shockwave-flash" allowfullscreen%3D"true" allowscriptaccess%3D"always" width%3D"640" height%3D"480"><%2Fembed><%2Fobject><%2Fp>%0D%0A <%2Fbody>%0D%0A<%2Fhtml>%0D%0A

What's the difference between a URI and a URL?

This gets fairly technical, but "URL vs. URI vs. URN, in More Concise Terms" has a good explanation.
