2. 2 What is an archive?

3. 3

4. 4 What is a digital language archive?  a trusted repository created and maintained by an institution with a commitment to the long-term preservation of archived material  has policies and processes for materials acquisition, cataloguing, preservation, dissemination, migration to new digital formats  a platform for building and conducting relationships between data providers and data users

5. 5 Why is language archiving different?  what is a language?  the data is not conventionalised (like $, age, year of publication etc) – what and how to code?  varying and competing expectations

6. 6 And endangered languages archiving?  extremely diverse context – languages, cultures, communities, individuals, projects  typical source - fieldworkers  typical materials - documentation  difficult for archive staff to manage  sensitivities and restrictions  extremely high priority

7. 7 What can a language archive offer?  Security - keep your electronic materials safe  Preservation - store your materials for the long term  Discovery - help others to find out about your materials, and you to find out about users  Protocols - respect and implement sensitivities, restrictions  Sharing - share results of your work, if appropriate  Acknowledgement - create citable acknowledgement  Mobilisation - create usable language materials  Quality and standards - advice for assuring your materials are of the highest quality and robust standards

8. 8 Different kinds of language archives  different contexts, systems, methods, collection policies  you should consider placing your materials in more than one …

9. 9 Why digital?  preservation: digitisation is the only way that audio and video (non-symbolic material) can be preserved for the future … because it can be copied and transmitted with zero loss  cataloguing, sharing, dissemination, repurposing

10. 10 Digital disadvantages  digital data is fragile and ephemeral  cost (human, equipment, maintenance)  requires strategy and luck to get right  preservation depends on file and data formats  depend on tools and software  depends on formats (prefer standard, open, explicit, long-lasting)  materials may have to be converted and migrated  some formats require particular software (can we archive the software?)

11. 11 What is archiving of language materials?  preparing materials  selecting  structuring  suitable encodings and formats  well-documented  depositing them in a suitable archive(s)  curation and accession by the archive  ongoing management, dissemination  new focus on form, presentation and user interaction/feedback

12. 12 Users and potential users  depositors – deposit, access or update materials  speakers and their descendants (“majority of users of Berkeley Language Center archive are community members”)  other researchers - comparative/historical linguists, typologists, theoreticians, anthropologists, historians, musicologists etc etc  other “stakeholders”, eg educationalists  journalists and the wider public

13. 13 Archives networks and bodies  foundation concepts and technologies from  library initiatives, eg. D-LIB http://www.dlib.org/  OAI (Open Archives Initiative)  OAIS Open Archival Information Systems (NASA and space agencies incl JAXA)  Open Language Archives Community (OLAC)  Digital Endangered Languages and Archives Network (DELAMAN)  ELAR, DOBES, ANLC, Paradisec, EMELD, LACITO, AIATSIS, AMPM (Maori)

15. 15 Endangered Languages ARchive (ELAR)  one of 3 programs of the Hans Rausing Endangered Languages Project  develop policies, preservation infrastructure, cataloguing and dissemination, facilities, training, advice, materials development and publishing

16. 16 ELAR facts and figures  archived collections: 110  online (published) collections: 50  average collection size about 60 GB  online data bundles: 9523  total number of files held: around 200,000  total volume of files held: around 10 TB  online data bundles unrestricted access: 5298  registered users: >500  annual downloads: >1,000  annual number of website "hits": 230,000

17. 17 ELAR facts and figures – user accounts  increasing number of community members, including Aleut (Canada), Tai-Ahom, Wadar (India), Burushaski (Pakistan), Serrano, Cahuilla, Arapaho (USA), Iraqi Jewish (Iraq), Saami (Finland), Wabena (Tanzania), Torwali (Pakistan), Hani, Bai (China), Irish  comments: “I found your site while looking up my grandmother, and i found her on your site speaking our language. and i would love for my children her great grandchildren to hear our language coming from her".  many interdisciplinary researchers, particularly archivists and anthropologists

18. 18 Archiving and data management  most data-related issues are really part of linguistic data/corpus management  there are now few data-related issues that are archive-specific  metadata formats  video  presentation/exhibition of material

19. 19 What can you archive (at ELAR)?  media - sound, video  graphics - images, scans  texts - fieldnotes, grammars, description, analysis  structured data - aligned and annotated transcriptions, databases, lexica  metadata - contextual information about the materials, structured and unstructured

20. 20 Archive objects  an “object” could be a file, a set of files, a directory, or a set of files with their relationships explicitly defined  these are often called “sessions”or “bundles”  they should be made explicit  through metadata  our future catalogue system will provide the ability for depositors to directly create, label and update bundles See bundles at ELAR

21. 21 Archive material should be selected  example: Depositor’s question: How much video can I archive?  answer:...

22. 22  resource(s) for an endangered language  it could be just one file  inventory / metadata  deposit form viewview  existing deposits can also be updated, added to, and metadata added/modified What is required to make a deposit?

23. 23 How can I deliver data?  hard disks  we return them  we send them out  email  good for samples for evaluation  OK for most text materials  Dropbox etc  flash cards and USB sticks  a web upload facility may be provided one day  we download from your server

24. 24 What about CDs and DVDs?  we have found CDs, and especially DVDs, to be very unreliable  DVD fail rate > 10%  cause confusion as files are allocated to fit on disks, not according to corpus structure  create a lot of work for depositors and for ELAR

25. 25 Protocol  the sensitivities and access restrictions associated with EL resources  need to be discussed, collected and recorded in the field  global protocol (the overall, typical value) is entered into the deposit form  specific protocol (for files, bundles) is entered via metadata (or any other explicit way)

26. 26 Protocol and access control  principles:  granularity – file, bundle or collection  access is a relation between object and user  protocol values can be changed over time  ELAR’s URCS system  User  Researcher  Community member  Subscriber

27. 27 “I have images”  what kinds of images?  what are their sources?  what is their documentation value? what role do they play in the collection?  … these should be reflected in the data structures/metadata

28. 28 Metadata for images  at least captions  what else?  …  in what form?  narrative  tabular fields  keywords

29. 29  get a list of image files  command (DOS) window  in directory  type “dir > list.txt”  open text file (in Notepad++ or MS Word)  change font to Courier  get a “vertical selection”  (or use a file listing utility!)  paste into spreadsheet Integrating images into metadata

30. 30 Integrating images into metadata  make a new sheet for images  paste in image file list (see previous)  add an ID column  type “1” in first cell  select from first to last cell in ID column  Edit>Fill>Series>OK  add other columns  now you can refer to your images anywhere!

31. 31 Using spreadsheet to access data  you can turn a filename into a link to access files directly from a spreadsheet  have the filename in cells  use the formula =HYPERLINK(file, “Message")  examples =HYPERLINK("E:\archiving\images\"&A2, "click here") =HYPERLINK(A1&A2, "click here") =HYPERLINK(A1&A2, A2)

32. 32 My cells have multiple values!  example: keywords  this is probably OK, as keywords are atomic  just consistently use a suitable delimiter  e.g. use comma - if data values cannot have commas  ELAR recommends double pipe “||”

33. 33 My cells have multiple values!  example: speakers in a recording  speakers are probably not atomic – they have other attributes  create a separate “speakers” sheet  give each speaker an ID (number or initials)  use the IDs in the original sheet, with delimiter (implements one to many)  (advanced) or make another sheet to associate recordings with speakers (implements many to many)

34. 34 Expressing “Relation” in spreadsheets  one column is usually insufficient  “relationship” has 2-parts  the target of the relationship  description of the relationship  how would this work for images?

35. 35 How can I tell if it’s Unicode?  use a browser or Notepad++  paste text in  examine the encoding (before and after)

36. 36 Can I still use MS Word?  ELAR no longer accepts MS Word files  but Word is still useful  quicker to type up  useful tables, functions, macros etc  solutions  think “text only”  tables as spreadsheets (are they bad too?)  (advanced) complex materials formatted as styles, then export as marked up  PDF/A – but not a perfect solution
