now with barcodes

The semantic web is about URIs, and every idea needs a URI. Each of my blog posts already got one, but now also in printed form. Look to the lower right, a mobile-phone readable QR code.

barcode for this post

Technically this all is age-old and I loved it already years ago when semapedia had its "uh-ah". The Nipponese, in the meantime, went for the full monty and covered their island coast-to-coast with QR codes, so we have to catch up.

For my mother of all cell phones E70, I use the i-nigma reader (ha, another enigma pun) because it was listed on Nokias page on barcode apps.

To hack twoday.net to render them I added a table after the blogposts in the "manage" menu - change template (html) - story.display - add somewhere this code (generated using i-nigma generator):

<!-- barcode -->
<img style="float:right" src="https://212.179.113.209/QRCode/img.php?d=URL%3Ahttp%3A%2F%2Fleobard.twoday.net%2Fstories%2F<%
story.id %>&c=blogcode&s=4" alt="QR barcode linking to this story. Useful when
printed." />

The leobard.twoday.net part needs to be replaced. It can probably be simplified by replacing the whole uri with <%
story.href %> but then I feared that the URL-encoding would break.

Next task for all Semantic Web lovers: print out and clue barcodes to all physical things that deserve a URI. And don't fuck it by picking an uncool URI, pick a cool uri for the semantic web.

Hey, what about the others!

Well done, Leo! I would just like to add that this is of course also a good idea if you don't consider yourself to be a LOVER of the Semantic Web ;-) It's also nice if you're just considering social media as something interesting :-)

social media is as good

and yes, you can use barcodes and readers for much fun, consider http://www.semapedia.org/ as a page where you find friends :-)

Different Reader

Why not embed a reader that lets you read these types of codes and 1D, Aztec, EAN, UPC.

Why not down load the NeoReader and try that. See if it gives you better results.

thx for the link

Looked at it, will download. Although E70 is not listed in the supported phones, I would guess it is.
