"IATE is a living database, i.e. translators and terminologists are continuously updating its content. In 2013, almost 97 000 new terms were added and 158 000 existing terms where modified. These changes were also reviewed and validated. Using the IATE search interface (http://iate.europa.eu/) thus ensures that you are accessing the most complete and up-to-date data. However, in order to cater for specific needs, you can also download a copy of some of the data contained in IATE.
The download file contains about 8 million terms in 24 official EU languages. It is provided in TermBase eXchange (TBX) format. For further details see: TBXcoreStructV02.dtd, TBXXCS.xcs, tbxxcsdtd.dtd.
The size of the uncompressed file is about 2.2 gigabytes."
