URIs, URLs, and Permalinks

Each Post has a unique identifying code that is used in the URL and is also used when linking between Posts. The Permalink URL for a Post includes the ID code and the title of the Post in the following format:

http://domain.com/blogname/ID_code_number/post_title.html

If the title of a Post is changed, the Permalink for the Post will change, but the ID code remains the same. If you have recorded the permalink and the title of the Post changes later, the URL will be directed to the correct Post because the ID code remains consistent.

The URI for the Post is a URL identifying the location and identity of the Post in the following format:

http://domain.com/uri/hexnumber

The URI is also constant and does not change when the Post is edited.

URI Labels

A URI Label displays the specific URI and URL for a specific Post. The URI Label is useful if you want to record the details of a specific Post that you have written, or you want to reference it in a different location. For example you might want to refer to a particular Post in your lab book, in a paper, or on a website. You can use the URI Label to create a barcode that can be printed out. An example use could be to link together a sample to the Post that describes the source of the sample or the steps used to create it.

To view or print the URI Label:

  1. Locate and click the title of the Post that you want to record.
  2. Click URI Label in the navigation menu. The URI Label Generator window is displayed. You can use the information displayed in this window to record the location of the selected Post. For example you could use on of the following methods:
    1. (Optional) Write down or copy the URI or URL to use to reference the Post from a new location.
    2. (Optional) Print the URI Label out.
    3. (Optional) To view a bar code for the Post, click just view label. A bar code reader is needed to read the information.
    4. (Optional) To view a QR code for the Post, click just view qr label.
  3. Close the URI Label Generator window when you have finished.

QR codes

As an alternative to using the URI, URL, or bar code you can view and print QR codes that provide a link to a specific Post. A QR reader is needed to read the information, for example many mobile phones with built in cameras have QR reading software. There are two ways to generate a QR code for a specific Post:

  1. Locate and click the title of the Post for which you want to create a QR code.
  2. (Optional) Click Show/Hide QR Code link under the subheading 'Tools' in the navigation menu. You can take a copy of the QR code by right-clicking on the image.
  3. (Optional) Alternatively to view a printable version of the QR code:
    1. Click URI Label in the navigation menu. The URI Label Generator window is displayed.
    2. Click just view qr label to view a QR code for the Post in PDF.

The QR code uses the URI in the form:

http://domain.com/uri/hexnumber

QR Code Software

To read QR codes you need a portable device with a camera and an internet connection. Most modern camera phones are of high enough quality to read QR codes.

  • Neoreader supports most mobile handsets.
  • Barcode Reader can be used with Android and Blackberry
  • Alternatively, search for 'Barcode Reader' in the Android market or other application stores.
