Concept of CyCAT url #
A CyCAT url is composed of a publisher short name, a project short name and the associated UUID of the specific item. An item can be any part of the collection produced by this publisher under a specific project. The CyCAT url is composed of two namespaces separated by colon and a final UUID appended after a colon. The CyCAT url is in UTF-8 format.
publisher-short-name:project-short-name:UUID
What is an UUID? #
A universally unique identifier (UUID) is a 128-bit number used to identify information in computer systems also known as GUID.
CyCAT uses such UUID to reference items produced in a collection. CyCAT, by default, will use any existing UUID already assigned by the publisher. If not present or there is no item present,
a fixed value is then calculated from the UUID namespace of CyCAT combined with publisher-short-name:project-short-name.
