- 1. 28 October 2015 Just Digitise It Community Heritage Grants Program digitisation workshop
- 2. Session outline 1.35 Arrival and welcome 1.40 - 2.40 pm Planning a digitisation project • Setting standards • Resources needed • Care of your originals • Care of your copies 2.40 - 3.00 pm Digitisation facility tour/ afternoon tea (first half) 3.00 - 3.20 pm Digitisation facility tour/ afternoon tea (second half) 3.30 - 4.00 pm Negotiating rights before you digitise Nicki Mackay-Sim, Curator of Pictures, NLA 4.00 – 4.30 pm Providing access • Getting images online • Metadata and sharing images 4.30 - 5.00 pm Q & A

- 5. Matching standards to the project Setting standards Two main impetus…es for digitisation • Preservation – OHIO (only handle it once) – colour management, ‘master’ copies • Access – search/ discoverability – crowdsourcing
- 6. Factors Setting standards • How much material to copy? • What condition? (preservation needs assesment) • How much time/ money do you have? • Has somebody already digitised it? (books…) • What is its significance? (significance statement, etc.)

- 16. Resources needed
- 19. Physical resources Resources needed • Space – managed, secure (fire, flood, pests, ancient wiring, not about to be reclaimed by Council for boutique carparks, etc.) – flat (shelving, tables) • Supplies – rehousing materials for copied originals – acid free paper, plastic film, gloves, pencils, spirit level, measuring tape/ rulers, gaffer tape, extension cables, USB sticks, random things that aren’t too grubby
- 20. Physical resources Resources needed • Toys! – Scanning equipment – Colour calibration equipment – Workstations – Storage
- 21. Human resources Resources needed • Project manager • Project committee (for when the manager heads off to Noosa) • Tame experts • Volunteers – what do you need from them? – what do they get out of it?
- 22. Documentation Resources needed • Digitisation policy/ strategy/ plan • Project statement/ plan • Risk management framework • Specific policies/ procedures • Written agreements with donors and digitisers • Passwords. Write them down.
- 23. Permission Resources needed • From your group • From your stakeholders • From your donors/ owners of the material • From your funders
- 24. Care of your originals
- 25. Collection management Care of your originals • Are the items catalogued? (Does the catalogue make sense?) • Are they securely stored? • Do you know who owns what? … things go missing.
- 26. Preservation management Care of your originals • put it in a box (controls light, humidity, physical safety) • wrapped in plastic (anything except PVC) • write on the enclosure, not the object • only take it out when you have to … things get old.
- 27. Relationship management Care of your originals • have some handling rules (gloves, induction) • digitisation providers should be able to describe their security and preservation measures • don’t break the original to digitise it … things get dropped.
- 28. Further further reading Care of your originals National Standards for Museums and Galleries • http://www.collectionsaustralia.net/sector_info_item/107 Keeping Archives
- 29. Care of your copies
- 30. Hardware failure Care of your copies • backups, offsite preferably • understand the limits of the storage technology • checksums – or just look at your images every so often
- 31. Hardware obsolescence Care of your copies • migration, vary your storage options • active management of collection
- 32. Software obsolescence Care of your copies • open formats (image formats have been stable for decades) • open applications (separate the data from the program) • plan for and budget migrations
- 33. Poor management and documentation Care of your copies • Bill is your IT guy. He has just fallen under a bus. • Try not to implement systems you don’t understand.
- 34. Hardware failure Digital Preservation • backups, offsite preferably • understand the limits of the storage technology • checksums – or just look at your images every so often
- 35. Summary Metadata • All of your data needs to be easily extractable from the software it’s in. • Create a simple file structure and make sure people stick to it. • Manage your backups properly (no lending to people, manage your risks, NO shortcuts).
- 37. Originals and renditions Getting images online • xyz
- 38. Originals and renditions Getting images online Constraints on delivering raw images • Connection speed and bandwidth • Screen size and resolution • Control over rights to the image
- 39. Options for publishing Getting images online • Don’t… • Use existing commercial tools and services (Flickr, Facebook, eHive) • Use existing community services (Victorian Collections) • Your own site (Wordpress, Omeka)
- 40. What and why to put online Getting images online • Marketing your organisation (‘going viral’) • Online archive (TROVE) • Storytelling • Online communities
- 41. Metadata and sharing images
- 42. Definition Metadata • Data about data (and data systems) • Look at the data surrounding an image in Flickr: http://www.flickr.com/ • Explore the Powerhouse Museum: • http://www.powerhousemuseum.com/ • Metadata reading: • http://en.wikipedia.org/wiki/Metadata
- 43. Metadata • Think about how your existing data can be: • Categorised into different functions (descriptive, discovery, preservation, etc.) • Standardised (eg. Dublin Core) enabling matches with other collections and websites.
- 44. Metadata • Important things to record: – Identity (title, ‘control symbol’) – Classification (subject, function) – History (dates, purposes) – [Description]
- 45. Identity Metadata • Some items may not have titles. What is the thing that distinguishes one item from the next in a collection? • Remember physical cues not same as digital. Perhaps the filename of your image is the title? • ‘Control Symbol’: Catalogue / collection / record-keeping number.
- 46. Classification Metadata • Information to manage items and help narrow down searches. • Library: ‘subject’ – what is it about? • Archive: ‘function’ – what does it do? • Internet: ‘tagging’ – where did I put it again? • Subject/ topic list for images: http://www.picturethesaurus.gov.au/
- 47. History Metadata • Archive/ Museum: ‘provenance’ – where is it from? (which collection, which donor) • Management history: what has happened to it? ie., what date was it scanned? • Scanning is another layer to existing management history that might be recorded in your collection database.
- 48. Description Metadata • Extended stories about item (mum on a bike) • Description of physical original – dimensions, special features • Description of digital copy – dpi, file format
