Uniform Resource Identifier (URI)
Each occupation, knowledge, skill and competence in ESCO is identified by a string of characters that follows a specific syntax: the Unique Resource Identifier (URI).
A URI is a crucial component of the Semantic Web. Each URI:
- is unique over the web (universal);
- allows data from different sources to link to it;
- is persistent (see ‘backward compatibility’ below for more information).
In the same way as a web address link (URL), if a URI is inserted in a browser, it points to the website where the resource is located. However, the difference between them lies in the fact that the URI is machine-readable.
