This record is a draft: it has not been reviewed yet and may be incomplete or wrong. Do not rely on it for compliance decisions. Help improve it (see CONTRIBUTING.md).

URN that cites a passage of a text by its canonical reference, used for classical Greek and Latin texts in the Perseus Digital Library, the Homer Multitext and other CITE/CTS projects. It has the form urn:cts:<namespace>:<work>:<passage>. The work part has up to four dot-separated levels: text group, work, version (edition or translation) and exemplar. The passage is a citation such as book.line, a range joined by a hyphen, or a node with a subreference such as @Atreus[1]. The specification requires the colon before an empty passage, but catalogues often omit it, so the regexp accepts both.
