Dear all,

(sorry if you've have received an email similar to this some time ago)

We´ve implemented a library of data cleaning functions in XQuery.
The most recent version has been distributed with the last release of  
Zorba query processor

In order to test exhaustively this library, we need to have XML data  
that have data quality problems known a priori.
By data quality problems, we mean: missing values, misspellings,  
values out of domain, approximate duplicates, etc.

We would like to ask you if you are aware of XML data sets in those  
that we can use to write data profiling and cleaning programs in XQuery.

Thanks in advance.
Best Regards,
Helena Galhardas
