Atlas 4.0 owl vs deer Fred van den Driessche Engineer
@fredvdd
What is Atlas? “the global video and audio index”
What is Atlas? • aggregates metadata from multiple sources •
stores in a uniform model • APIs + feeds provide consolidated data
What is Atlas? ATLAS DB BBC PA C4 etc... /content
/schedules /topics sitemaps radioplayer interlinking
Atlas Data Model brand item series version broadcast location
History •2008: 0.5 • MySQL • URIs • RDF •
POST to Update • /content
History •2009: 1.0 • Adapters • POST to Update
History •2010: 2.0 “otter” • MongoDB • denormalization • /discover
• /schedules • uploading
History •2011: 3.0 “owl” • MongoDB :-( • less denormalization
• /discover • annotations
DEMO
Objectives for 4.0 “deer” Easy scaling • Discovery • Faster
updates • More consistent, rational API • extensive use of HTTP
External Changes - quite small • IDs not URIs •
URL structures: /content/<id> not /content?uri=<uri> • More flexible filtering • Better annotations • Richer output • Better error handling • Consistently fast
Internal Changes - almost everything • New Technologies • New
Persistence Layer • Flexible Denormalisation • Bootstrapping • Queue
DEMO
Optional Extras • improvements to storage and indexing • monitor
all the things • small core • decentralization • queue-triggered processing • all data submitted via POST? • generalization of feed output • new equivalence algorithm?
