Preserving Digital Objects

When you're choosing file formats, choose an open format.

Don't rely on companies to migrate data for you.
Recommendation:
Read the files once a year.
Move to new media every 5 years.
Digital reformatting
File Formats
Open? Proprietary?
LOCKSS: Lots of Copies Keep Stuff Safe

At least 2 copies, plus the original.

Keep original on your computer, copies on other media (CDs, DVDs, Thumb drives, portable hard drives, Cloud storage), and store separately.
Getting Started
Sustainability
Maintenance
MAKE COPIES
In Four Simple Steps!
IDENTIFY your digital objects:
What is it?
Where is it stored?
Cameras
Computers
Memory cards
Websites
Phones
CDs/DVDs
Personal websites
Example:
Photographs from Jill and Jim's wedding, memory card in Kodak camera
DECIDE what you'll keep and what you won't
WARNING: You get out what you put in.
Pick objects you are attached to; think about "future use".

Pick as much or as little as you want to. (You can always go forward, but not always back.)

Save the highest quality of any object if you have multiples.
Then, update your inventory!
ORGANIZE your objects
Use descriptive file names.

Create a directory/folder structure.

Update your inventory again: this time, include a narrative of the directory structure so others can understand what you've done.
Batch Rename Files
So Simple!
1. Identify

2. Decide

3. Organize

4. Make Copies
Open: based on an underlying standard, created publicly by a community, fully documented and publicly available.

Proprietary: encoding is or is not published, use restricted (through licenses) such that only the company itself or licencees may use it.
