  • ---+ Shortening URIs with Virtuoso Long URLs are hard for humans to type or remember, and don't work very well with short message services like [[http://twitter.com/OpenLink][Twitter]] or [[http://identi.ca/kidehen][identi.ca]]. *CURIs* are compressed URIs which redirect to the original long URL. They are easier to share, type, and use in general. The Virtuoso URI Shortener offers a way to do this in your own domain and data space, without reliance on external services such as [[http://bit.ly/][bit.ly]], [[http://is.gd/][is.gd]], or [[http://tinyurl.com/][tinyurl.com]]. %TOC% ---++How does it work? All full-length URIs are stored in a Virtuoso database table which keeps a unique ID number for each URI. This ID is converted to base32 encoding, which only uses uppercase letters and numbers from 2 to 7, for use in the CURI. Note: numbers 1 and 0 are not used in this encoding, eliminating the common visual confusion between uppercase o and number 0, and between uppercase i, lowercase L, and number 1. ---+++ Configuration Options The prefix for loading images, CSS, etc., can be set through the Virtuoso INI file option, CURIUISkinPrefix. ---++Package Installation and Accessibility 1. Download the [[http://s3.amazonaws.com/opldownload/uda/vad-packages/6.2/virtuoso/c_uri_dav.vad][Virtuoso URI Shortener VAD]] package. 2. Install the package through the Virtuoso Conductor from the System Admin -> Packages tab or using the isql command line program as shown below: SQL> DB.DBA.VAD_INSTALL('tmp/c_uri_dav.vad',0); VARCHAR VARCHAR _______________________________________________________________________________ 00000 No errors detected 00000 Installation of "OpenLink Virtuoso URI Shortener" is complete. 00000 Now making a final checkpoint. 00000 Final checkpoint is made. 00000 SUCCESS 6 Rows. -- 1766 msec. 3.
