OData: There’s a Feed for That
Pablo CastroSoftware ArchitectMicrosoft [email protected]
Goals
• What is it?• Why do you care?• How do you use it?• How to build one?– Today at 3:00 PM
what were we thinking?
data in modern web applications
odata in 1 slide…
OData
• Uniform way of representing structured data– Atom, JSON formats
• Uniform URL conventions– Navigation, filtering, sorting, paging, etc.
• Uniform operations– Addressability– GET, POST, PUT, DELETE always mean the same
great experiences over an open protocol
data sharing in business applications(or how we learned to say “Information Worker”)
SharePoint 2010 & OData
• SharePoint needed 2 things in this space
• Flexible data interface– Maximize reach, minimum barrier of entry– Data centric, but enforcing business logic
• Developer story– Libraries for as many clients as possible– Great Visual Studio integration
Every SharePoint 2010 site is an OData server
Insight from Data
• “Self-service business intelligence”– Let people find and use their own data– …but where’s the data?
• Broad direct database access is impractical– OData feeds expose data over application logic– PowerPivot can handle OData natively
• Reports often represent the best data sources– All reports in Reporting Services are now OData feeds
data sharing at large
• Government data, e.g. OGDI• Scientific data, e.g. OSDI• Social data, e.g. NerdDinner• Commercial public data, e.g. Netflix, Mix• Premium data, Microsoft Codename “Dallas”
