You can label as many sites as you wish with a single labels file if you:
- include the domain names of the sites to be labelled in the labels file
- include links from all your sites to the single labels file.
The labels file includes a section like this:
example.org ...
This is written on a single line, but we’re limited for space here!
Simply repeat the hostRestriction line as many times as you need to cover your domains:
example.org ... example2.org ... example3.org ... example4.org ...
If the URL of the labels file is http://www.example.org/labels.rdf you can include the following tag in all your sites:
Perhaps you already share a stylesheet between different sites? The same thinking applies here.
If you have hundreds of sites
Some production companies run hundreds of sites with an ever-changing list of domains. The hostRestrictions can be held in a separate file if required. Edit the main labels.rdf file so that the hostRestriction entry is analogous to the example below:
http://www.example.org/hosts.rdf may then be the front end of a dynamic system that returns a list of host restrictions thus:
example.org example2.org example3.org example4.org ...
Note: For instructions on how to manually add further domain names to the PICS version of your ICRA label (which was delivered along with your Link tag), please see the PICS support section.
