This standard aims to facilitate international communication in the field of information and documentation. It presents a set of terms, in three languages, that deal with relevant concepts in the area of information and documentation, along with their definitions, and identifies the relationships that may exist between different entries. The definitions are established in such a way that the particularities of a given language are not presented. This part of the UNE 50-113 standard refers to the basic concepts of information and documentation used to describe traditional documents and also to other derived terms that are considered useful for practical applications.
