Almost exactly three years ago, I announced a plan on Phonoloblog: the plan to establish a Wiki for OT constraints, which should slowly grow into a large online reference on all constraints which have been proposed in the literature. The plan was born during a conversation with Curt Rice during the legendary Bloomington PhonologyFest of 2006.

The advantages of a ConCat are evident. It’s useful to have a tool where you can look up what has been written about a certain constraint, how it has been defined, which constraints are related to it, and whether some constraint has already been proposed in a different form or with a different name. Eventually, it could be a tool in the development of a true theory of possible OT constraints.

We established a website for ConCat in 2006, but it didn’t really grow since then. Maybe it was too small to be really attractive as a tool to use. This summer, however, I was fortunate enough to find two enthusiastic students from the University of the Aegean in Greece (Anna Fragkiadaki and Sofia Kousi) who filled the database with over 340 constraints, mostly excerpted from the handbooks by Kager and McCarthy, but also many other books and papers from the literature of the past 15 years.

I hope that in this way ConCat is becoming more useful. I hope you will see how useful it is, and that you start contributing.
