My understanding is that CTS and OpenURL are situated at different layers of the same architecture. Indeed, an OpenURL might be resolved into a CTS urm whereas the opposite it's impossible.

The OpenURL mechanism requires less knowledge than CTS about the target resources. The idea of such a link resolution service is that to make a request (i.e. to create an OpenURL) the user agent does not need any specific knowledge about the (location of) resources a given canonical reference can be resolved to. All this knowledge is added by CWKB in the link resolution phase.

I don't feel like I fully understand it, and OpenURL makes me nauseous, but the idea with CTS is that canonical citations can be resolved to actual text (XML) via a web service, whereas CWKB's purpose seems to be to resolve those citations to web references (Perseus, TLG, library holdings via WorldCat, e.g.).  

Both, broadly, are about making citations into actionable references.  

I'm not completely sure what the intended use case for CWKB is...

Can anyone on the list explain how this is the same as / different from the Canonical Text Services work by Neel Smith, and/or the similar work being undertaken by Peter Robinson at Birmingham? The concept seems to be the same but I'm curious about details. (My underlying question is, why is the same thing being done over and over, bah humbug.)

Thanks,
Dot

 Got Ovid? Classical knowledge base will assist in
 citing ancient Greek and Latin texts

 Scholars looking for multiple sources and
 translations from among 1,000 years of ancient
 Greek and Latin texts will have a powerful new
 tool in their research arsenal with a database
 being developed at Cornell.

 The Classical Works Knowledge Base (CWKB) -- a
 relational database and specialized link resolver
 software -- will facilitate linking from
 citations of ancient texts to the online versions
 of those texts. The database will ultimately
 cover all Latin and Greek authors from Homer to
 Bede, from approximately the eighth century B.C.
 to the mid-eighth century A.D.

 The Andrew W. Mellon Foundation recently granted
 $215,000 to the American Philological Association
 (APA) to implement the project, spearheaded by
 principal investigator Eric Rebillard, professor
 of Classics and history, in collaboration with
 Cornell librarians David Ruddy and Adam Chandler.
 The APA project also received a Mellon planning
 grant in 2008.

 "I got in touch with University Librarian Anne
 Kenney for consulting with library specialists
 about the possibility of using the OpenURL
 framework for linking citations to full texts.
 She organized a meeting, and after that the
 project developed in a collaborative way with
 David Ruddy in E-Publishing and Adam Chandler in
 Database Management," Rebillard said.

 Rebillard, Ruddy and Chandler have developed a
 working prototype at <http://cwkb.org/>.
 Rebillard expects the fully functional version of
 CWKB to be online in two years.

 CWKB works by parsing OpenURL links (commonly
 used in libraries to help patrons retrieve
 scholarly articles) once a citation has been
 clicked on. OpenURL metadata is sent to the link
 resolver, which "creates several links -- because
 you can have several versions for the same
 citation, in the original language and in
 translation," Rebillard said.

 "OpenURL was created about 10 years ago to solve
 this problem of linking from a citation to the
 full text," said Chandler, the database
 management research librarian who programmed the
 CWKB software. "The current OpenURL method of
 journal citation isn't quite what we needed, so
 we designed another metadata format for linking
 to these canonical works."

 The electronic version of the database of
 classical bibliography L'AnnĂ©e philologique (The
 Year in Philology) will be the first abstract and
 index database to propose such links to CWKB.
 Many other resources are potential users of the
 new tool.

   "For example, the works of the Founding Fathers
 are full of references to classical texts,"
 Rebillard said. "It would greatly enhance the
 reading of the Founding Fathers to have links to
 those texts."

   With applications for canonical citations in
 other fields and types of literature, the project
 can serve as a model and tool for scholarship in
 a number of disciplines.

   "We've wanted to keep the OpenURL metadata part
 of our project as widely useful as possible,"
 Ruddy said. "This work can be applied to any
 discipline that has developed conventions of
 textual citation which are reasonably independent
 of specific editions, such as in Biblical or
 Shakespearean studies."
