This International Standard identifies and describes a wide range of terminology products and services so that suppliers of these products and services and their clients can have a common understanding as well as shared expectations in their delivery. This International Standard outlines some of the generally-accepted terminology practices to be followed in the development and delivery of terminology products and services as well as some of the desired quality features that should characterize the products and services produced. This International Standard is intended as guidance for work contracts in the field of terminology. This International Standard focuses on terminology in specialized language as opposed to general language resources. For general language resources, i.e. lexicographical products, a standard is under development and will be available in the future.
