Introduction
Due to the value of digital assets due to the advancement of technology, digital technology is improving in ways that allow archivists an opportunity to make their collections accessible to a broader range of the people online. As archivists began utilizing digital technology to digitize their collections, or to preserve materials which are in danger of becoming unusable, or materials which should not be handled much, or even to preserve born-digital materials, digital archiving has led to allowing those from off-site locations to access materials from repositories online. Digitization allows for the preservation of digitized or born- digital materials to be stored for permanent storage within a digital archive. Digitization of these digital materials is supposed to keep digital files safe, as once files are uploaded they are able to be sustainable for preservation. Therefore, digital content can also be exported, or transferred elsewhere onto external storage devices, or onto shared drives before ingest, when an object or data is transferred into a digital repository, which can take place over not only one, but multiple systems and involves various actors who ingest.

Definition
When using an Open Archival Information System (OAIS), or an OAIS compatible system ingest is the receiving of information and the preparation process that goes into preparing information for external sources of storage. Ingest also relates to the management of digital content, such as the life cycle of archival digital files for instance. After material has been ingested into a system, such as into a system of an institution, the material can then be exported and can re-ingest somewhere else. According to Christopher A. Lee in “Open Archival Information System (OAIS) Reference Model,” for the process of ingestion, this is when the entity that receives and performs quality assurance, or quality checks of the SIP (the Submission Information Package), which is the external object that was prepared for ingestion into a digital archive, will generate AIPs (Archival Information Packages), which will then extract the Descriptive Information (metadata) from the AIPs, along with coordinating updates to Archival Storage and Data Management.

Ingest is not only an entity but is also one of the functions that are required for the preservation of digital materials after the transfer of digital data to an institution has been done. Ingest can occur in various sized batches of export, from small batches to exports of entire collections of an archive. In the Digital Preservation Essentials, for a case study Sibyl Schaefer, the former assistant director of Digital Programs at the Rockerfeller Archive Center wrote that prior to ingest, files must be prepared, metadata must be created, files will be arranged, and then they will be appraised in order to be uploaded and to ensure ingested files will survive in the long run. Files must also be checked for viruses, restrictions must also be taken into account, as well as looking at any rights related to the data to be ingested. According to the Consultative Committee for Space Data Systems (CCDS) in the Reference Model for an Open Archival Information System (OAIS),  besides digital materials, or objects, metadata is also something that can become ingested, such as metadata which is ingested into a different system then the location from which it originated, or came from. During this process, various standards, such as metadata standards, along with other archival standards, including the archiveʻs data acquisition policy must be followed in order to achieve proper preservation of digital materials. At the time of ingest, metadata is created relating to files which also determines whether the file format will be changed after it has been ingested.
