Metadata in Digital Objects Authenticity Significant properties Example digital objects Web pages TIFF files PDF Microsoft Word
Authenticity n. ~ 1. The quality of being genuine, not a counterfeit, and free from tampering, and is typically inferred from internal and external evidence, including its physical characteristics, structure, content, and context. authentic, adj. ~ 2. Perceived of as genuine, rather than as counterfeit or specious; bona fide. http://www2.archivists.org/glossary/terms/a/authenticity
Authenticity (notes) Authenticity is closely associated with the creator (or creators) of a record. First and foremost, an authentic record must have been created by the individual represented as the creator. The presence of a signature serves as a fundamental test for authenticity; the signature identifies the creator and establishes the relationship between the creator and the record. Authenticity can be verified by testing physical and formal characteristics of a record. The ink used to write a document must be contemporaneous with the document's purported date. The style and language of the document must be consistent with other, related documents that are accepted as authentic. Authenticity alone does not automatically imply that the content of a record is reliable. http://www2.archivists.org/glossary/terms/a/authenticity
Authenticity of digital objects “A large component of archival and museum metadata creation activities has traditionally been focused on context. Elucidating and preserving context is what assists with identifying and preserving the evidential value of records and artifacts in and over time; it is what facilitates the authentication of those objects, and it is what assists researchers with their analysis and interpretation.” Gilliland, A. 2008.
