ASSESSMENT OF UKDA AND TNA COMPLIANCE WITH OAIS AND METS STANDARDS The pre-ingest workflow at TNA follows the Producer-Archive Interface standard methodology, with some minor discrepancies. For instance, TNA accepts digital submissions to the digital archive only on official TNA branded CDs and DVDs, although exceptions can be made by special agreement, for example where a high data volume might dictate transfer media. These media carry a serial number that is tracked against which Government Department it has been issued to and what records are expected to be on it. The initial validation provides checks against digital records that are not required for their paper counterparts, for example, file corruption and technical usability of the digital record. TNA Web Archive harvests its content straight from the public internet for Government departments with which an agreement exists to archive from their web site. The relevant Operational Selection Policy defines the update frequency. OAIS Ingest Function 30 The functions of the OAIS standard Ingest entity that acts as the OAIS’s external interface with information Producers are illustrated in Figure 3. The five services included in this entity manage: the receipt of digital objects transferred to the OAIS; validation that the information received is uncorrupted and complete; transformation of the submitted information into a form suitable for storage, preservation and management within the OAIS archival system; extraction and/or creation of descriptive metadata to support the OAIS’s retrieval tools and finding aids; and transfer of the submitted information and its associated metadata to the archival store. ■ the Receive Submission function provides the appropriate storage capability or devices to receive a SIP from the Producer (or from Administration). This function provides a confirmation of receipt of a SIP to the Producer, which may include a request to resubmit a SIP in the case of errors resulting from the SIP submission; ■ the Quality Assurance function validates the successful transfer of the SIP to the staging area; ■ the Generate AIP function transforms one or more SIPs into one or more AIPs that conform to the archive’s data formatting and documentation standards. This function sends SIPs or AIPs for audit to the Audit Submission function in Administration, and receives back an audit report; Figure 3.
