Archival Information Package (AIP) Pilot Specification

This report presents the E-ARK AIP format specification as it will be used by the pilots (implementations in pilot organizations). The deliverable is a follow-up version of E-ARK deliverable D4.2. The report describes the structure, metadata, and physical container format of the E-ARK AIP, a container which is the result of converting an E-ARK Submission Information Package (SIP) into the E-ARK Archival Information Package (AIP). The conversion will be implemented in the Integrated Platform as part of the component earkweb

Request for proposals for industry review

The purpose of this Request for Proposals (RFP) is to select a Proposer to perform the Project services described in this RFP. SCDOT desires that this Project be constructed in a very efficient and timely manner. This proposal is for a design-build project for an emergency bridge project for Anderson and York Counties

Multi-Media Mail in heterogeneous Networks

The MIME approach seems to be the most reasonable effort for allowing the sending and receiving of multimedia messages using standard Internet mail transport facilities. Providing new header fields, such as MIME-Version, Content-Type, and Content- Transfer-Encoding, it is now possible to include various kinds of information types, e.g. audio, images, richtext, or video, into a RFC 822-conformant mail. Making use of these headers, it is possible to fully describe an attached body part, so that a receiving mail user agent is able to display it without any loss of information. Additionally, the definition of the "multipart" and "message" content types allows the creation of hierarchical structured mails, e.g. a message containing two alternative parts of information, one that can be shown using a simple ASCII-terminal, the other to be displayed on a multimedia workstation. Allowing the definition of bilaterally defined content types and providing a standardized means of establishing new content types prevent MIME from being a one-way road and supply mechanisms to extend MIME for future use

Specification and implementation of metadata for secure image provenance information

The booming of AI tools capable of modifying images has equipped fake media producers with strong tools in their arsenal. Complementary to the efforts of implementing fake media detectors, research organizations are designing a standardized way of describing the modification history of digital media in a cryptographically secure way, ensuring that this information cannot be tampered with. This thesis proposes a specification which focuses on JPEG images and specifies a data model based on the JPEG Universal Metadata Box Format (JUMBF) standard. Furthermore, it proposes the encryption of a subset of provenance metadata that could pose privacy-related risks to the users. Along with the specification, a library has been developed to manage provenance information of JPEG images. To that extent, a set of libraries that handle JUMBF information is required to be implemented. These libraries have been submitted as a proposed reference software contributing to the JUMBF standard

DCC Digital Curation Manual Instalment on File Formats

The goal of digital curation is to ensure the appropriate usability of managed digital assets over time. Format is a fundamental characteristic of a digital asset that governs its ability to be used effectively. Without strong format typing a digital asset is merely an undifferentiated string of bits. The information content encoded into an asset’s bits can only be interpreted properly and rendered in human-sensible form if that asset’s format is known. While it is possible for bits to be preserved indefinitely without consideration of format, it is only through the careful management of format that the meaning of those bits remains accessible over time. This instalment investigates aspects of format description, validation, and characterisation that may assist with long-term curation and usability of data
