Data on the Web Best Practices

Data on the Web Best Practices. W3C First Public Working Draft. 24 February 2015.
This document provides best practices related to the publication and usage of data on the Web. Data should be discoverable and understandable by humans and machines and the efforts of the data publisher recognized.This will help the interaction between the publishers and users.

Data on the Web allows for the existence of multiple ways to represent and to access data which is a challenge. Some of the other challenges include: metadata, formats, provenance, quality, access, versions, and preservation. The Best Practices proposed should help data publishers and data consumers overcome the different challenges faced during the data life cycle on the web. The draft proposes best practices for each one of the described challenges.

Cloud Storage and Digital Preservation: New guidance from the National Archives

Cloud Storage and Digital Preservation: New guidance from the National Archives. Laura Molloy. Digital Curation Centre. 13 May, 2014.
The use of cloud storage in digital preservation is a rapidly evolving field and this guidance explores how it is developing, emerging options and good practice, together with requirements and standards that archives should consider. Digital preservation is a significant issue for almost all public archives. There is an increasing demand for storage of both born-digital archives and digitised material, and an expectation that public access to this content will continue to expand. Five detailed case studies of UK archives that have implemented cloud storage solutions

Digital preservation can be defined as: “the series of managed activities necessary to ensure continued access to digital materials for as long as necessary, beyond the limits of media failure or technological and organisational change”. The challenges are urgent but can be taken one step at a time; you can address current technology and needs while ensuring that the content can be passed on to the next generation. With cloud storage there are many positives and negatives that must be considered. The article reviews many of these. When establishing your needs: Identify what are the ‘must have’ needs and what are the ‘wants’. Define your requirements and decide on the required capabilities rather than a specific technology, implementation, or product.

• We should be concerned about the security of data, wherever it is stored, but it would be unrealistic to suggest that most cloud services are inherently less secure than most local data centres.
• Adoption of a digital preservation strategy utilising cloud computing inevitably brings with it a range of legal questions.
• Cloud storage services can achieve significant economies of scale.
• Cloud services are typically considered to be operational rather than capital expenditure

Why Digital Storage Formats Are So Risky

Why Digital Storage Formats Are So Risky.  Matthew Woollard.  Lifehacker. 25 February 2015.
While it may seem that digital files last forever, the growing digital sphere faces enormous losses. Even Google has been unable to ensure access for its archive of digital content. Technical solutions already exist, but they’re not well known and relatively expensive.

How much are we prepared to pay to ensure that digital content that exists today will be usable in the future? We need to think about the value of the content and decide if it is worth keeping. Determining the value can be difficult. However, "re-use is a significant benefit from preserving data and adds value." Besides economic value, there are also cultural and intellectual reasons for preserving data. An example of preservation of data from the middle ages can be seen with scribes that used wax tablets for temporary records, and parchment for permanent records.

The chances of born-digital material being usable in 100 years will be considerably improved by actively taking steps now to ensure the preservation of the items. Effective digital preservation relies on the activities of the creator as well as the archivist. It is important to make decisions about providing context, the types of formats to use, how to organize the material, and resolving rights issues to avoid future problems.

Why we should all think about data preservation

Why we should all think about data preservation. Stephanie Taylor. School of Advanced Study. February 19, 2015.
The SHARD project, which ended in 2012, identified  four basic principles of digital preservation for researchers:

1. Start early: The sooner you start thinking about what to preserve, how to do it, and when, the greater the chance of avoiding problems. Early planning means involving everyone in a research project in the discussion to help identify additional issues.
2. Explain it: Context provides meaning and is vital in digital preservation. There is little point in preserving material and data without context.
3. Store it safely: Backups are not preservation. It needs multiple copies in different locations. Use open source file formats and be careful how you and others handle and access files. Select carefully the files to be preserved.
4. Share it: Sharing your research material and data is beneficial.  In one way or another, the main reason to carry out preservation at all, on any level, is to be able to share your work with others, now and in the future.

Many things are being lost or threatened because no one saw a good reason to preserve them until it was almost too late.  The Data Preservation Online Training resource guides students through the reasons to preserve and share data and challenges that they might face.

Enjoy your digital films and videos while you can... before they disappear

Enjoy your digital films and videos while you can... before they disappear. David Shapton. RedShark Publications. February 17, 2015.
Article about fragility of digital objects. Examples how digital files can fail even when there are multiple copies. Drives can fail, systems can be obsolete. Some statements:

• paid-for cloud storage and synchronisation company that seems to be doing OK today but which might not be here at some point in the future.
• Absolutely the most important thing to remember here is that this can happen right under your nose without you realising it. It's like they way you forget things.
• We can have backup strategies. But that's clearly not enough. There's no point at all in backing up all your files so that they're stored on accessible error-free media, only to find that you don't have any applications to play them.  
• Cerf has said "that we have to not only preserve the files, but the means to decode them as well."
• we also have to preserve a working copy of the operating system that can play back the media files, and because machines go out of date, we have to preserve a working copy of the machine.
• You don't get a warning when something is about to become obsolete or unreadable. You just get an error message bringing you the bad news, or the device doesn't show up in your file system explorer. 
• Data doesn't fade away gradually. It just becomes inaccessible. But when you step back and look at a mass of data from afar, the effect is that it gradually goes away.

It may be possible to create a virtual machine with a portable language, which could help resurrect machine/software combinations. Making this work will be work and expensive. "It will have to happen because if it doesn't, our films, videos, music tracks, personal memories, and in fact the whole of our recent (and future) history, will simply disappear."

From Theory to Action: Good Enough Digital Preservation for Under-Resourced Cultural Heritage Institutions

From Theory to Action: Good Enough Digital Preservation for Under-Resourced Cultural Heritage Institutions. Jaime Schumacher, et al. Digital POWRR White Paper for the Institute of Museum and Library Services. 27 August 2014.
The Digital POWRR team is comprised of archivists, curators, librarians, and a digital humanist, from small and mid-sized Illinois institutions who know that digital content is vulnerable, but are  lacking significant financial resources and have been unable to come up with programmatic and technical solutions to mitigate the risk. Each institution produced a case study and a gap analysis, with a plan to address the obstacles.  Some institutions have created and implemented digital preservation programs; however, medium-sized and smaller organizations with fewer resources like those of the POWRR institutions are in a vulnerable position.Some statements of interest:

• "Common elements emerged from our gap analyses: a lack of available financial resources; limited or nonexistent dedicated staff time for digital preservation activities; and inadequate levels of appropriate technical expertise. Some of the case studies also mentioned a lack of institutional awareness of the fragility of digital content and a lack of cohesive policies and practices across departments as a contributing factor towards the absence of real progress." 
• Digital preservation is best thought of as an incremental, ongoing, and ever-shifting set of actions, reactions, workflows, and policies.
• the notion that it is necessary to research all available tools and services exhaustively before taking any basic steps to secure digital content is yet another misconception that often prevents any progress from occurring.
• Fortunately, practitioners can get started with simple, freely available triage tools while researching which of the more robust solutions will best suit their needs.

The group developed the POWRR tool for evaluating solutions and tools. The appendix also has recommendations for the Developer Community.

Rosetta and Amazon Storage

Rosetta and Amazon Storage. Chris Erickson. February 2015.
In the search for more file storage, as well as more affordable file storage, we tried Amazon Simple Storage Service (Amazon S3). The plan was to connect the Rosetta Digital Preservation System to the Amazon cloud storage, and evaluate it as a possible storage solution. There is a free trial. The Free Tier includes 5GB storage, 20,000 Get Requests, and 2,000 Put Request.

Setup:
I tried various configurations, but decided on a single bucket for the files. I setup buckets for the IEs and metadata, but after trying it, decided to only keep the files on Amazon. That would keep the metadata local. I had tried nested folders, but couldn't figure out how to designate that in the storage rules and definition. So I create the folders by time period.

In the Rosetta Admin interface I create a File storage group, using the S3 storage plugin, and then entered the Bucket name, Secret Access Key, Access Key ID, and left the Maximum waiting time at the default. For the test, I set up a retention code for Amazon, and the storage rule used that code to determine what went to the Amazon storage. In a real storage instance, it would be better to use something that would not change, like the producer, etc.

It took a few tests to get everything in sync. The result was that Rosetta stored the content in Amazon just fine. I also tried adding content with a one day retention period, and the content was removed from Amazon after the day. A fixity check task was also able to work without a problem.

This gives us another storage option, though we decided to not use it at present.

Pricing at the time of this comparison, was:

	1 TB		50 TBs
Digital Storage Costs	Annual  Cost	20 Year Projected	Yearly  Charge	10 Year Projected	20 Year Projected	50 Year Projected
Cloud Storage
Amazon S3 - Regular	$360	$7,200	$17,706	$177,060	$354,120	$885,300
Amazon S3 - Copy / Glacier	$480	$9,600	$23,706	$237,060	$474,120	$1,185,300
Amazon S3 - Reduced & Glacier	$288	$5,760	$14,165	$141,648	$283,296	$708,240
DuraSpace - Preservation	$1,800	$36,000	$36,100	$361,000	$722,000	$1,805,000
DuraSpace - Dark copy/Glacier	$1,925	$38,500	$42,350	$423,500	$847,000	$2,117,500
DuraSpace - Enterprise Plus	$5,625	$112,500	$64,425	$644,250	$1,288,500	$3,221,250

More storage options will be considered.

Save the Voices of Tolkien, Joyce And Tennyson

Save the Voices of Tolkien, Joyce And Tennyson. Laura Clark. Smithsonian. January 14, 2015.
The British Library issued a public call for help safeguarding the over 6.5 million recordings in their archives through digital preservation. It will take around £40 million to fully fund the effort, and time is running short. The British Library’s sound archives includes audio files from Tolkien, Joyce, Florence Nightingale, Tennyson, WWI soldiers, as well as many nature sounds, oral histories and theater performances.  Thousands of others are at risk and will disappear soon if no action is taken.

AHRQ Public Access to Federally Funded Research

AHRQ Public Access to Federally Funded Research. Francis D. Chesley. Agency for Healthcare Research and Quality. February, 2015.
The Agency for Healthcare Research and Quality's  has established a policy for public access to scientific publications and scientific data in digital format resulting from funding through the agency. Preservation is one of the Public Access Policy's primary objectives.

The Public Access Policy includes the following objectives:

• Ensure that the public can access the final published digital documents.
• Facilitate easy public search, analysis of and access to these publications
• Ensure the attributes to authors, journals, and original publishers are maintained.
• Ensure that publications and metadata are in an archival solution.
• Ensure that all researchers receiving grants develop data management plans, describing how they will provide for long-term preservation of and access to scientific data in digital format.

Data management plans will include:

• A plan for protecting confidentiality and personal privacy.
• A description of how scientific data in digital format will be shared
• It must include a plan for long-term preservation and access to the data

The data management plans will be evaluated based on the values of long-term preservation, access, and the associated cost, and administrative burden. AHRQ will contract with a commercial repository to ensure long-term preservation and full access to the public.

Digital scientific data is defined as "the digital recorded factual material commonly accepted in the scientific community as necessary to validate research findings including data sets used to support scholarly publications, but does not include laboratory notebooks, preliminary analyses, drafts of scientific papers, plans for future research, peer reviews, communications with colleagues, or physical objects, such as laboratory specimens."

Internet future blackout: No way to preserve our data

Internet future blackout: No way to preserve our data. Lisa M. Krieger. San Jose Mercury News. February 12, 2015.

Vint Cerf spoke about the "digital vellum" needed to maintain the data that comprise text, video, software games, scientific data and other digital objects, and how to preserve their meaning.

Aiding preservation might involve "Information Centric Networking," which is based on two simple concepts -- addressing information by its name, rather than location, and adding computation and memory to the network. David Oran of Cisco Systems and Glenn Edens, research director of Palo Alto's Xerox Park, are working on that new technology.

Google is not directly involved in the digital preservation effort "although we have worked really hard at preserving the digital information of the day. We aren't planning to become the archive of the future -- although I think it would be cool." Cerf envisions libraries and governments investing in the technology needed to carry today's information into the distant future.


The "digital vellum" project led has been created at Carnegie Mellon University. This is how it would work: There's a digital snapshot of a document, which is then built into one giant file. Using preserved and transmitted instructions, a virtual computer pretends to be a 2015-era Mac or IBM computer, and can find the document. "If I can substantiate those bits (of a document) in another computer, years in future, then I will have created the same document -- I can reproduce what you were doing. It is a digital copy of the state of the computer you were using when you created new documents."

Rather than the current paradigm -- names, addresses and routes -- it would start with an "object," with a name, as the thing to be stored and moved. "Our current system of 'domain names' is not a stable system. The current routing system could be replaced by the information-centric system, where we keep track of everything not by where it is hosted but the information itself, by name.
Just as we need preservation of today's bits and software, our encryption systems will need to be preserved as well -- because once they're lost, so is the material that they're protecting. "We need an encryption system in which the keys never wear out and are never broken, that represents keying for hundreds of thousands of years."

Google VP leads calls for web content preservation

Google VP leads calls for web content preservation. Caroline Donnelly. IT Pro.  13 Feb, 2015.

Vint Cerf says action is needed to preserve the content of the internet for future generations to enjoy. Historians in the future could may view the 21st century as an “information black hole” because the software and services used to access online content could become defunct over time. To protect against this, he wants to see efforts made to create a “digital vellum” that will preserve the hardware and software needed to access online content in the years to come. "If we want to preserve them, we need to make sure that the digital objects we create today can still be rendered far into the future.” All web users are at risk of throwing their data away into a “digital black hole” in the mistaken belief that uploading content to a site or service will preserve it. “We digitise things because we think we will preserve them, but what we don’t understand is that unless we take other steps, those digital versions may not be any better, and may even be worse than, than the artefacts that we digitised.”

Crystal clear digital preservation: a management issue

Crystal clear digital preservation: a management issue.  Barbara Sierman. Digital Preservation Seeds.
February 1, 2015.
The book Digital Preservation for Libraries, Archives and Museums by Edward Corrado and Heather Lea Moulaison does a great job of explaining to people about digital preservation. "In crystal clear language, without beating about the bush and based on extensive up to date (until 2014) literature, digital preservation is explained and almost every aspect of it is touched upon. " It explains what digital preservation is not (backup, etc.) The point of the book is expressed by the statement:
“ensuring ongoing access to digital content over time requires careful reflection and planning. In terms of technology, digital preservation is possible today. It might be difficult and require extensive, institution-wide planning, but digital preservation is an achievable goal given the proper resources. In short, digital preservation is in many ways primarily a management issue”.
It uses the Digital Preservation Triad to symbolize the interrelated activities of

• Management-related activities,
• Technological activities and
• Content-centred activities.

The book, which is also available as an eBook, has a practical approach and emphasizes that “that digital preservation is important to the overall mission of the organization”, and not just an experimental project.

Save our Sounds

Save our Sounds. Luke McKernan. British Library.  12 January 2015.
The nation’s sound collections are under threat, from physical degradation, and also as play back devices wear out and disappear. "Archival consensus internationally is that we have approximately 15 years in which to save our sound collections by digitising them before they become unreadable and are effectively lost." The British Library collection contains over 6.5 million recordings of speech, music, wildlife and the environment, from the 1880s to the present day. The Save our Sounds program has three major aims:

1. Preserve as much as possible of the nation's rare and unique sound recordings from collections across the UK
2. Establish a national radio archive to collect, protect and share with other partners
3. Invest in new technology to enable us to receive music in digital formats, working with  industry partners, to ensure their long-term preservation

The library is seeking to raise funds to help the preservation efforts, and to implement a national audit to map sound archives in the UK and to find those that are at risk.

New Expert Panel Report From Council of Canadian Academies Says Canada’s Memory Institutions “Falling Behind” in Preservation of Digital Materials

New Expert Panel Report From Council of Canadian Academies Says Canada’s Memory Institutions “Falling Behind” in Preservation of Digital Materials. Gary Price. Library Journal. February 4, 2015.
An expert panel report, Leading in the Digital World: Opportunities for Canada’s Memory Institutions, (208 pages; PDF) addresses the challenges and opportunities that exist for libraries, archives, museums, and galleries as they adapt to the digital age. Vast amounts of digital information are at risk of being lost because many traditional tools are no longer adequate in the digital age. Memory institutions face the difficult task of preserving digital files in formats that will remain accessible over the long term. Institutions to collaborate more strategically and develop interactive relationships with users. They must also be leaders within and among their respective organizations. Many of the challenges faced are rooted in technical issues associated with managing digital content, the sheer volume of digital information, and the struggle to remain relevant. Collaboration is essential for adaptation, which enables institutions to access the resources required to deliver the  services that users now expect.

Reference rot in web-based scholarly communication and link decoration as a path to mitigation

Reference rot in web-based scholarly communication and link decoration as a path to mitigation.
Martin Klein, Herbert Van de Sompel. LSE Impact of Social Sciences blog. February 6, 2015.
The failure of a web address to link to the appropriate online source is a significant problem facing scholarly material. The ability to reference sources is a fundamental part of scholarship. "Increasingly, we see references to software, ontologies, project websites, presentations, blogs, videos, tweets, etc. Such resources are usually referenced by means of their HTTP URI as they exist on the web at large. These HTTP URIs allow for immediate access on the web, but also introduce one of the detrimental characteristics of the web to scholarly communication: reference rot." Reference rot is a combination of two problems common for URI references:

• link rot: A URI ceases to exist; the page is not found
• content drift: The resource identified by its URI changes over time and is not what was originally referenced

Their study shows that articles published in 2012 suffer from link rot: 13% of arXiv, 22% of Elsevier, and 14% of PubMed Central. For articles published in 2005, the numbers are higher: corresponding numbers are 18%, 41%, and 36%.

The typical strategy to address the problem is to link to a snapshot of the web page (instead of the original web page) created at the time and stored in a web archive, such as the Internet Archive, archive.today, and perma.cc.

 There are problems with the approach. The link copy may not remain in place either. The linking URI is lost, as is the any information about the page or changed page. Link decoration can be used, with the URI of the original, the snapshot, and datetime of linking. Memento can provide this information but there are discussions needed to decide how to best convey the information.
