5 minute lightning talk about Dbd "A database that never forgets" at Arrrrcamp 2013 (excuse the primitive formatting)

1. Dbd
A data store that never
forgets
@peter_v

2. RDF based
Triple: "subject predicate object"
subject (URI): resources
predicate: standardized (e.g. foaf)
object: value or URI

3. +Fine grained
"context"
provenance (source)
privacy level (public, prviate, ...)
encryption level (clear, key_1, key_2, ...)

4. +Append Only
Storage
"never forget"
"windowing" of data sources
"perfect" backup (in 1 file)
privacy (clean the 1 file)
Nathan Marz: defense against faults
need to revoke old fact

5. Implementation :
Fact
s p o +
context_id : points to a context
id : an unique uuid (revocation)
time_stamp : monotonic order (windowing)

6. A personal exercise
in Code quality
travis-ci (MRI 1.9, 2.0, JRuby)
codeclimate (4.0)
pullreview (lots of hints)
#pairwithme (e.g. @marksim)
