Abstract/Résumé/Resumen
From the perspective of digital preservation and archival custody over time, it is seen that systems and repositories of document management and storage structure the evidence, the result of institutional transactions. At that moment the digital environment of a digital archive service translates as the set of platforms and models, responsible for guarding the archival documents registered in binary sequence. When comparing the digital environment with the record continuum model, one can see the structure of the document flow from the business environment to the diffusion environments. The Chain of Custody may be related to the Digital Curation Life Cycle, since both seek, in their own way, to guarantee the authenticity, reliability and integrity of archival documents. For this, a chain of custody must be maintained, from the management environment to the preservation environment, incorporating the natodigital documents as a priority. As a result of the study, it was possible to establish the relationship between Digital Curation, Digital Preservation and Chain of Custody, since digital curators guarantee long-term data sustainability and perform maintenance, preservation and value adding actions the data throughout its useful life. Already the custody, which includes the chain of actions and responsibilities over time, aims at the custody and protection of files, similar to the actions of Digital Curation. Finally, digital librarianship, digital archiving, and data management and data science stand out.
