Description
Canonical Text Services (CTS) is a protocol to identify and retrieve passages of text cited by canonical reference.

The Canonical (previously 'Classical') Text Services specification defines a network service for identifying texts and retrieving fragments of texts using notions of "work" and "citation" traditional in classical studies and other literary disciplines.

CTS is part of the CITE architecture, developed by Blackwell and Smith to meet the needs of the Homer Multitext project.

Applications

 * One classical project which uses Canonical Text Services is the Homer Multitext (cf. information on its blog).
 * The Perseus Digital Library also relies on CTS architecture, see . Perseus' CTS end-point is accessible at http://cts.perseids.org/api/cts/? (an interface to browse the repository can be found at http://cts.perseids.org/).
 * The corpus Croatiae auctores Latini (CroALa) is in the process of adding support for the CTS protocol. For a subset of CTS-compliant texts from CroALa see https://github.com/nevenjovanovic/hc-croala
 * The texts in Alpheios Tools are available via a CTS API (endpoint at http://repos1.alpheios.net/exist/rest/db/xq/CTS.xq?)
