In the last few years, the international organization for standards ISO has started up various projects concerned with the definition of interoperable concepts for syntactic, morphosyntactic, and semantic annotation, with the ultimate aim to support the development of interoperable language resources. The Linguistic Annotation Framework (LAF, Ide & Romary, 2004) thereby serves as a meta-framework. LAF distinguishes between the concepts of annotation and representation: 'annotation' refers to the process of adding information to segments of language data, or to that information itself, independent of the format in which this information is represented. The term 'representation' refers to the format in which an annotation is rendered, for instance in XML. According to LAF, annotations are the proper level of standardization.
