Some of you may recall my comments on Oyster: A Configurable ER Engine, a configurable entity resolution engine.
Software wasn’t available when that post was written but it is now, along with work on a GUI for the software.
Oyster Entity Resolution (SourceForge).
BTW, the “complete” download does not include the GUI.
It is important to also download the GUI for two reasons:
1) It is the only documentation for the project, and
2) The GUI generates the XML files needed to use the Oyster software.
There is no documentation of the XML format (I asked). As in a schema, etc.
Contributing a schema to the project would be a nice thing to do.
