witness what happens to the bulk of peoples' print photographs: They are stored in boxes, kept relatively safe, but not captioned.Intrinsic metadata may be automatically collected based on user activity, device properties, or environmental sensors (e.Naturally intrinsic metadata will introduce new privacy concerns, since we are not accustomed to digital items keeping such close tabs on their own provenance.It has been the assumption of most archiving applications that an individual's digital assets should be centralized in a single trusted repository.As it is, people hedge their bets and scatter their digital belongings among online services according to the functionality offered or the audiences promised, or based on other circumstantial factors (storage limits; one account's password is remembered and another's isn't).USB drive is at hand and a CD isn't, for example, or a desktop computer has lots of available storage and a laptop doesn't.For example, suppose an individual has used a social media service to share a personal collection of photos.The catalog may reveal that there are enough other active copies that it's not necessary to do anything.Others subscribing to these photos may also want to know they are disappearing and may want to move their own copies to a safer place.According to study informants, they may have a variety of reasons for using one service over another, and these reasons shift over time.But youtube isn't for backup though.""Because in Taiwan people always use msn spaces.It is not uncommon for people to articulate similarly complicated rationales for why they have put some digital belongings in one place, and others in another.For example, Web email accounts are set up so that it is difficult for most users to store and view their email locally; they also enjoy the ubiquitous access to their email.An individual might copy files back and forth from a laptop to a desktop computer to work on them in both places; these copies may be in different states of completion.In the case of a photo, it may be the original as it was taken off of the camera's memory before any color correction has been undertaken.As long as there are multiple copies being using in different ways, it is only necessary to maintain the reference to the item and the item's metadata.As copies disappear for one reason or another, it is important to know when an item of significant value is in danger.An account expires and email notification fails, for example.Where did this copy come from?The photographer might rotate the image 90 degrees initially to orient it correctly.Then he or she might do some simple image enhancement.Later, a sophisticated image manipulation program like PhotoShop might come into play; while the original image is not overwritten, another version in a different format is created as a result of this image manipulation.Finally, when the image is attached to an email message, its resolution might be radically reduced.Later, when the photographer is asked what to do with a copy of the image, it is crucial that he or she knows that there are other copies, where they came from, and what the differences among them are.Today, provenance is inferred, from the filename and its variants, from other file metadata (such as file date), or from visual inspection of a rendering.So I don't know what I did in this case."Much of the information about relationships among files is recorded implicitly and reconstructed by inference.Which Word document did a PDF file come from?The author will examine file dates to find out or will assume one file is derived from another because the name is the same although the file type has changed.Current practice among computer scientists is to bundle related files together as a compressed whole at storage time.Note that if this bundling is done at creation time, these relationships do not need to be inferred nor specified explicitly.Rather, they can simply be recorded at the outset.We often assume that digital stewardship is simply a matter of storing the data once and recovering it when we would like to see it thirty years hence.It seems productive to divide curation in three different kinds of activities: (1) invisible, routinized activities that involve every item and that can potentially be automated; (2) communal activities that take advantage of a group's, a community's, or an institution's investment in keeping material organized, labeled, and culled; and (3) individual activities that we can neither automate nor distribute among community members (i.IT is often performed in a very ad hoc way with whatever help is locally available.IT functions that must touch every file and that may change dramatically over time.The file will be modified as a result of use (as it would if a creative process were resumed).It is always possible that we will get it wrong during any initial format normalization or during any one of a number of migrations as the years go forward.Retaining the original digital object may also be necessary from the standpoint of provenance.This has always been true to a certain extent with our physical belongings.Often one member of a family is the de facto historian, maintaining the photo album, labeling individual pictures, recording and organizing the home movies, or keeping the box of 'treasures' safe and accessible for the rest of the family.Unfortunately, these types of expertise may not be embodied in the same person; for communal curation to be effective, it must be designed for the individual with expertise in the subject matter.Internet services companies to develop a sense of what cultural stewardship means.Trust and security interests need to be balanced.Finally, at the heart of communal collection maintenance, a financially sustainable enterprise must be created to form its backbone.At some point, individuals simply must be involved with the maintenance of their own stuff.At the heart of any personal archiving endeavor lies the individual who has the judgment to say what's important and what's not and sufficient desire to keep his or her assets that he or she is willing to perform minimal curatorial duties.Security is one of the most troubling aspects of maintenance.How much security is enough?We have already seen that one way people lose digital materials is that they simply lose access to them: they lose accounts and passwords.Yet if such a capability were folded into a personal digital archive, it would address a very real problem in a way consistent with current practice.Finally, it should come as no surprise that curatorial tools should take advantage of distinctions in genre.Photos should be tended as photos, records as records, and movies as movies.New modes of access will need to be developed to tackle the problems of accumulated personal digital assets.Other difficulties arise from the standard practice of replicating items, both for backup and for specific purposes (for example, to share them); as we have discussed earlier in this article, as time passes, it is difficult to know where the highest resolution version of a photo is or whether the photo has been somehow modified.You have no need to remember what's in the box, just that it's where the valuables are.Because it is not unusual for people to forget what they have (even if it is valuable) or misremember its salient characteristics, even the best desktop search engine will not meet the requirements of long term retrieval.Tools for finding and choosing among duplicates.One of the key advantages of digital artifacts is that they can be copied and changed so easily.It is important to be able to get from one copy to the others and to identify which copy is the ground truth, the photograph as taken, the original video footage, or another form of reference copy.Much of the time, this will not be necessary.However, it will be necessary to have viewers that will display material independent of the original application and its functionality.Instead, what will be needed are viewers that allow users not only to examine content, but also inspect the item's provenance and understand why we thought the item was valuable.If you want to convince yourself of this, try going through Flickr's photos in the multiple available representations; it's easy to see how the ability to fit a large number of photos onto a single page can help with a visual search task.It is easy to fall into various traps when we talk about personal digital archiving: that it's not a problem, that it's not my problem, that it's a problem of data and media formats, that we should just keep everything and worry about it later, that we should hop to it and build a comprehensive library of emulators or encode every digital object so it knows how to render itself, or that it's simply intractable and pointless to even think about personal digital archiving, and we should let the bits fall where they may.In some sense, these aren't exactly traps.These are ordinary situations and shouldn't be catastrophic.ASKED HIM ABOUT IT that he explained...On one hand, it is normal and perhaps even necessary to lose a certain amount of one's digital stuff to the forces of benign neglect.If we were able to keep everything (as many computer scientists propose), would we ever want to go through this unmanageable accumulation, even if it were filtered sensibly?We move a few times, lose a few boxes, feel the pangs of regret, but in the end, we're left with a lighter load.Don't we want to lose some of the heavy burden of our own history?People don't lose just a few of the baby pictures of their first child; they lose ALL of them.What we want then is a combination of services and mechanisms that will make it possible to designate which of our digital things are the most valuable; to organize the rest of them into tractable archives that reflect the items' value; and to not spend all kinds of extra time taking care of them.It's best not to become a slave to one's own stuff.Personal archiving technology should fit organically into everyday practice: it should take advantage of the fact that increasingly we're storing stuff online, on social media sites, in blogging tools, on web sites, in online banking systems, in medical records repositories, and so on."The good thing about the photos is that there's always an intermediary step.So I always have master copies on my PC.So that's why I don't care so much about Flickr evaporating."We want to be sure such pleasures remain possible and within our reach.Cottan for invaluable fieldwork assistance and data analysis help.Thanks too to Doug Terry and the CIM project.This is not unlike the trend in institutional repositories: instead of believing that scholars will deposit their publications and datasets in multiple repositories, or in one central repository, we have come to realize that it is more effective to federate at the metadata level.They may, in fact, correspond to a repository of the sort that dominates the archiving literature.Tori Orr has written a fascinating literature review that covers how biographies and social histories might be indexed to facilitate retrieval (see Orr, 2004).From home visits, I know that most people have naughty photos on their computers, even if the person doesn't seem to be "the type".Fleischhauer, "Digital Formats: Factors for Sustainability, Functionality, and Quality."Teevan, "Searching to Eliminate Personal Information Management."American Life Project, 6 July 2005.Ingen, "Empirical Measurements of Disk Failure Rates and Error Rates."Challenges in the Preservation of Electronic Information," International Preservation News, 17 (May 1998).Levy, "Heroic measures: reflections on the possibility and purpose of digital preservation."Lib Magazine, 5, 9 (September 1999).From Writing and Analysis to the Repository: Taking the Scholars' Perspective on Scholarly Archiving.To appear in Proceedings of JCDL 2008.Marshall, "How People Manage Personal Information over a Lifetime."Minor, "Disk and Tape Storage Cost Models."Society for Imaging Science and Technology, Springfield, VA, 2007, pp.Oard, 2006, "Using Rhythms of Relationships to Understand Email Archives," Journal of the American Society for Information Science and Technology, 57, 14, pp.In Proceedings of Interact 2003, pp.Rothenberg, "Ensuring the Longevity of Digital Documents."Directorate for Computer and Information Science Engineering
