Scalability issues with Web-scale consumption
hinder discovery of this knowledge
Use low-cost TPF framework to expose archives
Which books were
present at time X?
Support different query types
Storing data as
Independent copies Changesets Timestamps
Supported query types and storage strategies form trade-offs
between client load, server load and server storage cost.
Roadmap
1. Extending TPF interface for different query types
2. Storage solution(s) for supported query types
3. Client-side methods for handling different versions
Which books were
added and removed
between times X and Y?
At what times was
book A present?
