There are multiple client libraries for it. https://github.com/OpenRefine/OpenRefine/wiki/Documentation-For-Developers#known-client-libraries-for-refine Trevor Muñoz wrote a great blog post about his work doing just that http://trevormunoz.com/notebook/2013/08/19/refining-the-problem-more-work-with-nypl-open-data-part-two.html Chad On Wed, Oct 25, 2017, 12:19 PM Péter Király <[log in to unmask]> wrote: > Hi Eric, > > I am planning to work on detecting such anomalities.
