UNL Standards for Language Engineering (USLE)

In addition to the UNL Specs, and in order to standardize the language resources in the UNL framework, the UNDL Foundation recommends the adoption of several specifications for creating lexical databases and grammars. These specifications, however, although highly recommendable, are not mandatory, as they concern to subsidiary aspects of the UNL. In any case, they must be followed by those interested in using UNDL Foundation tools.
