Specs
The UNL Specs define the structure of UNL. They have been stated by the UNL Center and specify the structure of a UNL document; the syntax of a UNL sentence; the syntax of Universal Words; the set of relations; the set of attributes; and all the information concerning UNL as a formalism.
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. This latter specifications, however, although highly recommendable, are not mandatory, as they concern to subsidiary aspects of the UNL, and must be followed only by those interested in using UNDL Foundation tools.
