Appendix A. LDAP Data Interchange Format

When information in the directory is represented in multiple languages, the server associates language
tags with attribute values. When a new entry is added, the attribute values used in the RDN (relative
distinguished name, the naming attribute) must be provided without any language codes.
Multiple languages can be stored for a single attribute. In this case, the attribute types are the same,
but each value has a different language code.
For a list of the languages supported by Directory Server and their associated language tags, see
Section D.2, “Identifying Supported Locales”
.
NOTE
The language tag has no effect on how the string is stored within the directory. All object
class and attribute strings are stored using UTF-8. The user is responsible for converting
the data used in the LDIF to UTF-8. The
iconv
or
uconv
command provided by most
operating systems can be used to convert data from the native characterset into UTF-8.
For example, Example Corporation has offices in the United States and France and wants employees
to be able to view directory information in their native language. When adding directory entries, the
directory administrator chooses to provide attribute values in both English and French. When adding a
directory entry for a new employee, Babs Jensen, the administrator does the following:
1. The administrator creates a file,
street.txt
, with the French street address value:
1 rue de l'Université
2. The file contents are then converted to UTF-8:
iconv -t UTF-8 -o output.txt street.txt
3. The following LDIF entry is created using the UTF-8 value of the street address value for
streetAddress;lang-fr
.
dn: uid=bjensen,ou=people,dc=example,dc=com
objectclass: top
objectclass: person
objectclass: organizationalPerson
name: Babs Jensen
cn: Babs Jensen
sn: Jensen
uid: bjensen
streetAddress: 1 University Street
streetAddress;lang-en: 1 University Street
streetAddress;lang-fr
:: AasljdoaAJASI023909jaASJaonasd0ADS
preferredLanguage: fr
The double colons after the attribute name and subtype indicate that the value is binary base-64
encoded.
Users accessing this directory entry with an LDAP client with the preferred language set to English will
see the address
1 University Street
. Users accessing the directory with an LDAP client with the
preferred language set to French will see the address
1 rue de l'Université
