Paper presented at the 12th International Conference on Digital Preservation, November 2-6, 2015. University of North Carolina at Chapel Hill.
Abstract:
Digital curation is a complex of actors, policies, practices, and technologies enabling successful consumer engagement with
authentic content of interest across space and time. While digital curation is a rapidly maturing field, it still lacks a convincing unified theoretical foundation. A recent internal evaluation of its programmatic activities by the University of California Curation Center (UC3) led quickly to seemingly simple, yet deceptively difficult-to-answer questions. Too many fundamental terms of curation practice remain overloaded and under-formalized, perhaps none more so than “digital object.” To address these concerns, UC3 is developing a new model for conceptualizing the curation domain. While drawing freely from
many significant prior efforts (e.g., Kahn-Wilensky, FRBR, NAA, OAIS, BRM, etc.), the UC3 Sept model also assumes that digital curation is an inherently semiotic activity. Consequently, the model considers curated content with respect to six distinct analytic dimensions: semantics, syntactics, empirics, pragmatics, diplomatics, and dynamics, which refer respectively to content’s underlying abstract meaning or emotional affect, symbolic encoding structures, physical representations, realizing behaviors, evidential authenticity and reliability, and evolution through time. Correspondingly, the model defines an object typology of increasing consumer utility: blobs, artifacts, exemplars, products, assets, records, and heirlooms, which are respectively existential, intentional, purposeful, interpretable, useful, trustworthy, and resilient digital objects. Content engagement is modeled in terms of producer, owner, manager, and consumer roles acting within a continuum of concerns for originating, organizing, and pluralizing curated content. Content policy and strategy are modeled in terms of six high-level imperatives: predilect, collect, protect, introspect, project, and connect. A consistent, comprehensive, and conceptually parsimonious domain model is important for planning, performing, and evaluating programmatic activities in a rigorous and systematic rather than ad hoc and idiosyncratic manner. The UC3 Sept model can be used to make precise yet concise statements regarding curation intentions, activities, and results.

Seminar: OAIS Model application in digital preservation projectsMichael Day
Presentation slides from a seminar on the Reference Model for an Open Archival Information System (OAIS) at La preservación del patrimonio digital: conceptos básicos y principales iniciativas, Ministerio de Cultura, Madrid, Spain, March 15th, 2006
Paper presented at the 12th International Conference on Digital Preservation, November 2-6, 2015. University of North Carolina at Chapel Hill.
Abstract:
In this paper, we describe an OAIS aligned data model and architectural design that enables us to archive digital information with a single core preservation workflow. The data model allows for normalization of metadata from widely varied domains to ingest and manage the submitted information utilizing only one generalized toolchain and be able to create access platforms that are tailored to designated data consumer communities. The design of the preservation system is not dependent on its components to continue to exist over its lifetime, as we anticipate changes both of technology and environment. The initial implementation depends mainly on the open-source tools Archivematica, Fedora/Islandora, and iRODS.
This short presentation is intended as a light interlude linking two practical sessions in a workshop connecting preservation planning with tools provided for use with EPrints repository software.

Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

47. Plato: The PLANETS Preservation Planning Tool A preservation plan defines a series of preservation actions to be taken by a responsible institution due to an identified risk for a given set of digital objects or records (called collection). The preservation plan takes into account the preservation policies, legal obligations, organisational and technical constraints, user requirements and preservation goals and describes the preservation context, the evaluated preservation strategies and the resulting decision for one strategy, including the reasoning for the decision. It also specifies a series of steps or actions (called preservation action plan) along with responsibilities and rules and conditions for execution on the collection. Provided that the actions and their deployment as well as the technical environment allow it, this action plan is an executable workflow definition. Access to a library of preservation plans. Source

64. Digital Curation Micro-Services “Micro-services are an approach to digital curation based on devolving curation function into a set of independent, but interoperable, services that embody curation values and strategies. Since each of the services is small and self-contained, they are collectively easier to develop, deploy, maintain, and enhance. Equally as important, they are more easily replaced when they have outlived their usefulness. Although the individual services are narrowly scoped, the complex function needed for effective curation emerges from the strategic combination of individual services.” Source

Digital Curation Software Tools Pronom File Format RegistryPRONOM is a resource for anyone requiring impartial and definitive information about the 320+ file formats, software products and other technical components required to support long-term access to electronic records and other digital objects of cultural, historical or business value. It is maintained by The National Archive(UK). Source Source
77. Digital Curation Software Tools FITS (Developed by Harvard University) The File Information Tool Set (FITS) identifies, validates, and extracts technical metadata for various file formats. It wraps several third-party open source tools, normalizes and consolidates their output, and reports any errors. Current tools are: Jhove, Exiftool, National Library of New Zealand Metadata Extractor, DROID, FFIdent, File Utility, Fileinfo andXMLMetadata. Source

80. Digital Curation Software Tools FITS (DROID Tool – file identification) DROID (Digital Record Object Identification) uses internal and external signatures, maintained in the PRONOM technical registry, to identify and report the specific file format versions of digital files. Source
81. Digital Curation Software Tools FITS (JHOVE Tool – file identification, validation and characterization) File identification as per DROID File validation A file is well-formed if it meets the purely syntactic requirements for a format.For example, a TIFF object is well-formed if it starts with an 8 byte header followed by a sequence of Image File Directories (IFDs), each composed of a 2 byteentry count and a series of 8 byte taggedentries. Source
82. Digital Curation Software Tools FITS (JHOVE Tool – file identification, validation and characterization) File validation (continued) A well-formed file is also valid if it meets additional semantic level requirements.For example, an RGB file must have at least three sample values per pixel.

88. Digital Curation Software Tools BagItA specification for the packaging of digital content for transfer. Content is packaged (the bag) along with a small amount of machine-readable text (the tag) to help automate the content's receipt, storage and retrieval. There is no software to install. A bag consists of a base directory containing the tag and a subdirectory that holds the content files. The tag is a simple text-file manifest, like a packing slip, that consists of two elements: An inventory of the content files in the bag A checksum for each file Source Source

142. Open DiscussionAlternative options for integrating Archivematica or a subset of digital curation micro-services into your digitization workflow.
143. Issues Institutional repositories are also used to maintain an institution’s bibliography, with frequent updates of descriptive metadata and object files. When should digital objects from an IR be preserved?
144. Issues Dappert, A. & Enders M. Using METS, PREMISand MODS for archiving eJournalsD-Lib Magazine Volume 14 Number (9/10)http://www.dlib.org/dlib/september08/dappert/09dappert.html “AIP per generation” generation: change in md and/or object file
145. Issues Both ArchiveMatica and LOCKSS are looking into solutions for the normalization of objects and packaging. Both systems seem redundant at first. How does ArchiveMatica interact with LOCKSS?
146. Issues ArchiveMatica-AIPs, DSpace-AIPs, exchange of packages between digital archives, nationwide preservation solution. Need for interoperability standards? TIPR: Towards Interoperable Preservation Respositories RXP: Repository eXchange Package
147. AIP Repository Interoperability “For reasons of redundancy, succession planning and software migration, repositories must be able to exchange copies of archival information packages with each other. Every different repository application, however, describes and structures its archival packages differently. Therefore each system produces dissemination packages that are rarely understandable or usable as submission packages by other repositories. “ Source
148. AIP Repository Interoperability One possible solution: RXP (Repository eXchange Package), developed by the Towards Interoperable Preservation Repositories (TIPR) project which has defined a standards-based package of metadata files that can act as an intermediary information package, the RXP, a lingua franca all repositories can read and write. Another option: create AIPS followingthe HathiTrust specification for digital objects. Source Source
149. Issues AIPs are intended for perpetual access and therefore only contain objects that comply to an open documented format. Any human being within 50 years should be able to re-read the contents of the object files, given a textual documentation. So, why migrate AIPs into a new(er) format?
150. Issues Archivematica normalizes moving pictures into MPEG2 = loss of quality Lossless conversion would be Motion JPEG2000 However: no open-source CLI-based tool for conversion into Motion JPEG2000 format available
151. Issues The more copies of a digital object are stored all over the place, the less trivial becomes control of copyright. Is geo-independent perpetual archiving in contradiction with IPR issues?
152. Issues Packages are self-contained: if you find an AIP, you know what it is about, and you can read, look, hear it. But how do you find the AIP in a see of billions of AIPs? Don’t forget to preserve finding aids! How?
