The domain is the field of knowledge to which the concept belongs. An IATE entry should usually have between one and three domains. Domains are indicated at the language-independent level (LIL). Read more about the language-independent level (LIL).
IATE currently uses version 4.6 of EuroVoc ☍, the European Union’s multilingual thesaurus managed by the Publications Office, in its entirety, as the domain classification for IATE entries.
EuroVoc ☍ divides the hierarchy of these fields of knowledge into:
- domains (level one), i.e. the broadest, most general fields, which are preceded by two digits,
- subdomains (level two), which are preceded by four digits, and
- descriptors (levels three to eight), which are not preceded by any digits.
Additionally, a second LAW branch (14 LAW) has been added to include the specific classification used by the Court of Justice of the European Union (CJEU).
Since some of the subdomains under the CJEU LAW branch are also present in the EuroVoc domain classification, the domain filter available in the search and in IATE downloads will retrieve results for both of the equivalent or ‘identical’ domains.
 To look for domains, you can either browse the domain classification by expanding and collapsing the different domains, subdomains and descriptors individually (using the black arrows  ) or by expanding the full tree at once, or you can search for a keyword in the search field. To find the relevant domain, search with the term, a simplified form of the term, a synonym or a slightly more general term. |

Once you have identified the relevant domain, subdomain or descriptor, click on it to add it to the list of selected domains.
To remove a domain from your selection, hover your mouse over it in the domain tree or in the list of selected domains, and click on the bin  icon. |
 You can reuse the set of domains selected in a particular search by saving them: click on the clipboard  icon and hit the ‘Save to clipboard’ button in the domain selector. The next time you open the domain selector, your saved domains should be displayed automatically. If you have several sets of saved domains, insert the most relevant of these by clicking ‘Insert from clipboard’. |
If you are creating or updating an entry, and two or more cascading domains are selected (a domain and one or more subdomains belonging to it), the system will issue an alert, as this is not considered good practice.
| If you work on an old entry imported from previous databases, it might have an incorrect domain or the domain code 00. Please correct the domain in these cases. Old entries might also contain domain notes which usually correspond to a descriptor that was not available in IATE at the time. Ideally, the content of these notes should be transferred to the ‘Domain’ field by selecting the appropriate descriptor, and the domain note should be removed. |
