We strongly believe bringing knowledge to places and things that matter to others is a great way to help others understand our beautiful and complex world. To accomplish this, we invite you to create and distribute Semapedia-Tags which are in fact cellphone-readable physical hyperlinks to the free online encyclopedia Wikipedia (or any of Wikipedias' sisterprojects such as Wikibooks, Wikinews , and Wikinews ). You can create such Tags easily yourself by choosing and pasting a Wikipedia URL into our creation-form . Pressing the button will generate a custom PDF file to download and be printed.
ZXing (pronounced "zebra crossing") is an open-source, multi-format 1D/2D barcode image processing library implemented in Java. Our focus is on using the built-in camera on mobile phones to photograph and decode barcodes on the device, without communicating with a server.
CrossRef has created a sample API that will take a CrossRef DOI and turn it into a QR Code. The QR Code will include the title of the document pointed to by the CrossRef DOI as well as the “htttp://dx.doi.org” URL of that will allow you to link to that item. Most mobile phone QR Code readers will allow you to bookmark, share or link to the URLs thus encoded.
