I was trying to find a flat list of RadLex terms that just had the IDs and descriptions. You can easily browse RadLex using the RadLex Term Browser, but my requirement was to do a quick lookup using a local database. I couldn’t find something online that was readily available, so I wrote some code to extract just the Id, description fields from RadLex.owl (which you can download from http://www.radlex.org/). In the attached file you can find the list of 34k+ RadLex terms. It’s an Excel file, so you can easily import it into a SQL Server or MySQL database. I can’t upload a tab delimited .txt file to WordPress.com (see http://en.support.wordpress.com/accepted-filetypes/), so if anyone needs the file in a different format, just let me know.
8-Nov-2012 update: Seems like there’s a new SQL script that contains all RadLex terms – ftp://ftp.ihe.net/RadLex/documentation.html. I haven’t used it yet, but might be better/newer/more complete than the original Excel file I put together.
