JISC has funded a Digital Repositories Roadmap document to look towards the UK academic repositories infrastructure in 2010. The authors suggest that by 2010 there will be a firmer basis for a national preservation strategy that makes clear who has responsibility for preserving different types of data and who has responsibility for providing open access to resources. A significant aim is to explore national and institutional preservation responsibilities and provide institutions with a preservation audit toolkit.

Since its inception, the OAIS reference model has been widely adopted within the digital preservation community. Initially developed by the Consultative Committee for Space Data Systems (CCSDS), the reference model was approved as an ISO standard by the International Organization for Standardization in 2003 (ISO 14721:2003). According to CCSDS and ISO procedures, the standard must be reviewed every five years, and a comment period to begin this process has been established. Comments and suggestions are invited, categorised under one of these headings:
- updates needed for clarification
- updates to add missing concepts or strengthen weak concepts
- identification of any outdated material.
Comments must be received by 30 October 2006.
A consortium of Harvard University, Portico, and Stanford University submitted a proposal to the Library of Congress under the National Digital Information Infrastructure Preservation Program (NDIIPP) initiative for a project called JHOVE2: A Next-Generation Architecture for Format-Aware Digital Preservation Processing. JHOVE2 builds on JHOVE, an open source framework for the identification, validation and characterisation of various file formats. This proposed project will seek to retain existing JHOVE functionality and refactor the existing architecture, support enhancements, increase the range of supported formats, and develop modules for supporting key preservation processes. Input from the JHOVE user community will be sought as part of the design phase.

In recent months the espida Project (An Effective Strategic model for the Preservation and disposal of Institutional Assets) has published two papers and released a beta version of the espida Model for general use and evaluation. The espida project at the University of Glasgow aims to provide a method to value intangible assets in order to construct convincing business cases to ensure the preservation of information objects. The papers published espouse that value should be considered as a counterpoint for costs. Both papers provide a perspective on the content of the project and the logic their methods have followed. The beta version of the espida Model is now available for download from the project Web site. The model provides a process and set of tools contained within five documents, and can be used to assist creating business cases, assessing change decisions and evaluating proposals involving normally intangible benefits. The documents include cost and value templates which articulate both financial and non-financial benefits or impacts.

Two interesting papers have been published that discuss how people approach personal archiving, including managing the obstacles and issues that can occur in the archiving process.
With the goal of designing a Personal Information Management (PIM) service, an article by Marshall, Bly and Brun-Cottan provides useful background information on how home computer users are creating, receiving and archiving their data. The study highlights the obstacles faced in PIM such as inconsistent and piecemeal approaches to the problem and lack of technical support. There is also the notion among home computer users that digital data is long lived, so minimal intervention is required.
Another paper by Catherine Marshall also looks at PIM and will become a chapter in a forthcoming monograph, Personal Information Management: Challenges and Opportunities. The author discusses the importance of the long term storage of personal digital information with regard to seven issues and then outlines some technological developments that may go some way to address these issues. The issues include predicting value, distributed storage, long term access and format obsolescence. The article presents several scenarios and a case study highlighting the long-term issues in PIM.

A paper by Thomas and Martin discusses the key aims of the Paradigm (Personal ARchives Accessible in DIGital Media) project and outlines some of the project's initial findings. These findings relate to how archivists might select, acquire, process, store, preserve and provide access to the digital archives of individuals for the use of future researchers. The article fuses archival and digital curation theory with the practicalities of working in a testbed situation involving personal digital collections and papers of British politicians. It also analyses the implications of exponential growth in the creation of personal digital collections - from digital images, and music files to personal Web sites and blogs - and concludes with a discussion of what this may mean for the wider archival profession.

The International Organization for Standardization approved the Open Document Format (ODF) as an international standard in early May. ODF is an open standard to allow sustainable reading and exchange of common office documents. Using open standards like the XML based ODF aims to ensure that users' information is accessible across platforms and applications, even as technologies change. Acceptance of this standard is predicted to be a significant step towards the long-term viability of digital documents.
In March 2006 an organisation was formed to support and encourage the use of ODF in the public sector. The ODF Alliance is a coalition of over 30 organisations from around the world and its mission is "globally to educate policymakers, IT administrators and the public on the benefits and opportunities of the OpenDocument Format".

The Internet Archive has released a new service. Archive-it is a subscription service established by the Internet Archive together with various partners from state archives and university libraries. It allows subscribers to build, manage and search their own unique Web archive containing only the content they are interested in harvesting. This allows these collections to be more in-depth and focussed on a particular area than the general Web archive. Archive-It collections have more functionality as they can be searched in full text, whereas the Internet Archive, via the Wayback Machine, cannot be searched in this way. The Web site provides tours of the user interface and applications, an extensive list of FAQs and access to the archived collections of the pilot partners.

In April, the OpenRAW initiative, seeking digital image preservation through open documentation, published results from a survey undertaken between January and March this year. The survey was conducted to provide an opportunity to digital photographers, archivists and other interested parties to voice their opinions regarding proprietary RAW imaging formats. The OpenRAW Web site states that 'More than two-thirds of the 19,207 participants expressed concern that they won't be able to open or edit raw files created by older digital cameras.'

CLIR published a report in March, commissioned by the National Recording Preservation Board of the Library of Congress, which assesses current standards and practices in capturing analogue sound for digital preservation. The report is based on a meeting of audio experts held in January 2004. It includes summaries of the meeting discussions and recommendations on practices and procedures for transferring analogue discs and tapes. It also includes a 'road map' for analogue to digital conversion.

In May, a new wiki was launched by PrestoSpace which features extensive information on audiovisual preservation. Developed by Richard Wright, the Preservation Guide covers many areas including mapping archive holdings, developing a preservation strategy, preservation planning, budgeting and storage options. Much of the wiki uses information from PrestoSpace and other sources of information will eventually be incorporated. It is planned that entries will be able to be edited and maintained by the audiovisual preservation community.

In June, the AHDS (Arts and Humanities Data Service) released the final draft of the report Moving Images and Sound Archiving Study. The report is part of a series of feasibility studies produced by the AHDS which aim to assess the preservation risk and retention criteria for digital content. The Moving Images and Sound Archiving Study has been funded to understand more fully the preservation challenges of digital moving image and sound files, to scope the preservation requirements and to determine archiving methodologies and future research directions. Issues that relate to moving images and sound that are explored include their properties, preservation methods, metadata, life cycle models and assessment of preservation costs.
