
Sorting
/Students?$orderby=Name desc
Filtering
/Classes?$filter=substringof(Name, ‘Math’)
Paging

Inline expansion
/Students?$expand=ClassRegistrations
Entity Data
Model
URIs
HTTP
Formats
• The underlying model
• Entities and associations  resources and links
• Every resource is addressable via a URI
• Flexible URI scheme for data retrieval
• Data as resources, HTTP verbs to manipulate it
• Follows AtomPub protocol
• Leverage caching, proxies, authentication, …
• AtomPub, JSON
