Digital preservation by Chris Smart

Editor's Notes

  1. Introduction. National Archives mandate to preserve and make available the resources of the commonwealth. We have no say in the formats we receive, but we need to preserve them long-term. We can't take chances. Apologies for the technical nature, not sure of the audience.
  2. Humans can already process the information on a piece of paper, because we understand the language (i.e. English). We know when something is a photo, we know when there's a table, we understand the context. Digital files are in “computer format”. We need a computer to interpret the file and then use some program to display it to us in a human readable manner. Once we have this, we are at the “paper stage” and can understand the document. Microsoft Word might be used to display a Word document, but without Microsoft Word, the computer cannot (necessarily) interpret the file. Ever had someone send you a file and you couldn't open it? You need a program/machine to read the format, i.e. Betamax. If there's no machine, the information is lost. Here's something that might shock you...
  3. It's true. For example, they can only count to one (sort-of). They can only manipulate data, they cannot create something out of nothing, and they can only do what they are told. But they have one saving grace....
  4. Computers can do mathematics faster than you. Faster than anyone, even though they are just manipulating ones and zeros to get the answer!
  5. If you take one thing away from this presentation, take this. Everything digital is just ones and zeros. That's all computers process, bunches and bunches of ones and zeros. Everything that sits on your hard drive is written to the disk as ones and zeros. When you browse the Internet, it's all ones and zeros. You don't see the ones and zeros though, you see what they represent because the computer translates them for you. Example: Using Microsoft Word to create a document. You type in “The quick brown fox jumps over the lazy dog” but what actually gets written to disk is not those letters, it's zeros and ones which represent those letters.
  6. zero = off one = on
  7. And so we have kilobtyes - one thousand (and 24) bytes Megabytes - one thousand (and 24) kilobytes, etc. Why 1024? Computers are binary, so everything is measured in powers of two. 2 ^ 0 = 1 2 ^ 1 = 2 2 ^ 2 = 4 2 ^ 3 = 8 2 ^ 4 = 16 … . 2 ^ 9 = 512 2 ^ 10 = 1024
  8. You're all familiar with counting in base-10. The first “ones” column can go up to 9, after which we put a one in the “tens” column and start again at zero in the ones column. Computers count in base-2, so they can only go up to a 1 in the first column, then they have to populate the next column. Demo – looking at files in binary.
  9. Because computers to lots of different things, there is no single meaning behind any one combination of bits.
  10. Here's a byte. What does it mean? Anyone?
  11. It would equal 97 in the decimal system. What else?
  12. In ASCII, this means the lowercase letter “a”.
  13. It could be a musical note, a symbol, my whole name, anything.
  14. You need something that tells you, I guess.
  15. So then if a clump of binary could mean anything, how do you know what it means? You need a specification which outlines what that means.
  16. They specify how data is constructed and stored within a digital file. Each file format is unique. Proprietary file formats. Microsoft Office (inc OOXML < ISO Strict) Open file formats. OOXML ODF (ISO Strict) Free file formats. ODF
  17. The ASCII file format specification says, that 097 in decimal (written as 01100001 in binary) is the lower case letter a. So if you ever have an ASCII file, you know how to interpret the data!
  18. What happens if you spill a cup of coffee on a paper record? You can still read and make sense of the document. What happens if you change just a few of those bytes in a digital file?
  19. In this case, you can still open the file, but you see the result. In the majority of cases, you simply cannot open the file at all!
  20. It makes sense to store your data in a file format which you can have access to in the future. Not all file formats are created equal. Open file formats which allow proprietary extensions, or are tied to other proprietary technology, are not truly open (e.g. OOXML < ISO Strict). Putting your data in a free and open file format, means that even if there is no software that can read it in the future, you can at least write some. Compare this to reverse engineering a proprietary format, which is far too time consuming and costly (not to mention it isn't guaranteed).
  21. Microsoft Works, Microsoft Money, Microsoft Mix, Wordstar, Ami pro, Clarisworks, AppleWorks?
  22. Including: Corel Draw Lotus Notes PowerPoint pre 1997 Word 1 & 2 Word <= 5 for Mac “ Legacy Binary Files” Reliant on one vendor much?
  23. Supported by more products, because able to implement freely. Only way to achieve true interoperability.
  24. The NAA approach is about risk mitigation. If we can read the proprietary file, great. If not, we have another in an open format. Like for like format, i.e. Microsoft Office to ODF (not PDF). It's good to know when a file might become obsolete, but in a way, free and open files never become obsolete, because they are always accessible. Issues with migration: Quality assurance – migrating from proprietary files. Platform specific components (macros). These issues would disappear if agencies would use a truly open format in the first place!
  25. Free and open source Java application (GPLv3). Free for anyone to implement, study and modify. Easy to use graphical interface, call as a backend, or use as a library (must be GPL compatible). City of Perth interfaces with TRIM.
  26. Xena screenshot, processing in the front, Xena viewer in the back.
  27. Once you have your data in a secure open format, you need to do the other important preservation step, manage the records.
  28. All open source software, like Xena. Needs external cataloguing system (e.g. RecordSearch).
  29. Manifest Maker takes a bunch of files and creates a list of them (including their name, location and checksum), to prepare for digital preservation work.
  30. DPR is a workflow tool that initiates a digital preservation job. It imports a manifest list and tracks the records over their life time, records preservation treatments, stores it in the digital archive, exports files for access.
  31. Checksum Checker constantly checks for file corruption – it is important to replace corrupt files immediately.
  32. Want to test your own Digital Archive? It's as easy as installing the DPSP.
  33. Everything is open source, but often geared to our needs. Don't be frightened off if something isn't exactly what you want, talk to us! You can build on what we’ve already done.
  34. Digital Archive hardware is vendor agnostic, built on open source technology. Migrated to new contemporary storage every few years to avoid physical media obsolescence.
  35. Current model is archaic, based on air gaps. Plan to move to a more modern system in the near future.
