3. Quick description of APTrust:
Provides simple, collaboratively designed and built preservation environment (bit-level with fixity checking) for the digital scholarly and cultural record (NOW)
Will provide collaboratively developed services for that content (FUTURE), which may include:
access
format migration
emulation
others TBD
Currently uses Amazon Web Services (as back-end platform only)

4. Three content copies in East Coast data center (three separate availability zones)
S3 service
(preservation)
for metadata
and events
Files go to S3 preservation bucket. Metadata and PREMIS events go to Fedora. We delete the file from the receiving bucket.

5. Three content copies in West Coast data center (three separate availability zones) + Fedora copy
APTrust copies them to Glacier in Oregon.

6. Money
Sustaining Members pay $20,000 per year in dues
Engage in governance, strategic direction-setting, development, etc.
Get allocation of 10 TB of content (with replication, total of 60 TB)
University of Virginia provides $400,000 per year toward staffing costs
Institution wishes to deposit more than 10 TB of content?
Pass-through of incremental costs in 5 TB blocks of content
previous estimate is $4,250/5 TB/yr, but likely to drop by at least $1,000 if costs “at scale” continue on current trend
Approximately $500,000 cash reserve
Serves as DPN ingest/replicating node (full cost-recovery from DPN)
Current volume (as of October 19)
52,000 content objects
16 TB (most of which has been ingested in the past month)
Two institutions anticipate exceeding initial allocation within a month
More preparing deposits “at scale”

7. Future
Much more volume in deposits
Develop collaborations for additional services
Develop sophisticated reporting for depositors
Services for non-members
Challenges
Drive costs downward to encourage preservation
Technical architecture enables interchangeable back-end platforms
Balance between
importance of Trusted Digital Repository certification
cost and frequency of TDR audit
increased assurance through encryption at rest
increased risk through encryption at rest

Time Frame
Year-to-Year
20 years
Diversification
Virginia & Oregon data centers; future technical diversity (planned)
At least three dispersed node data centers; multiple node-specific technologies
Content Disposition
Controlled by depositing institution
Provides possibility for DPN to “brighten” content in future
