OData Future Directions

 

V4.1 Issues

·         NavigationPropertyBinding on NavProp

·         Capabilities for NavProps

·         Deep Update with $refs instead of odata.bind

·         Streams & Etags

·         JSON metadata

·         Unsigned integers

·         Dictionaries / Property Bags

·         Set Operations (delete where, update where)

·         Delta apply

·         Beautificaton

o    URL

·         No parens for functions

·         No namespaces for bound functions if defined in same schema → name collision with properties not allowed

·         Path segments for keys instead of parens

o    JSON

·         Omit odata. in standard instance annotations, i.e. allow @count, @nextLink

·         Batch

o    Unwrapped async responses

o    Content-id referencing across change sets

o    Content-ids for inserting links

 

FAQ

·         What is the performance of OData

o    Why no binary format

o    Why no "table" format

·         Why not my own custom REST

·         Is it secure?

o    Refer to Securing OData

·         Libraries for ...

·         RDF

·         Who is using OData?

·         Is there a vocabulary for …

·         How do I register my vocab for …

 

Tips & Tricks

·         Performance

o    Use server-driven paging

o    Other formats (binary for reduced processing)

·         Defaults for referential constraints vs. SQL

·         Case-sensitivity

·         Model versioning

 

Interpretations

·         Pre-Errata2

·         Etag-handling in change sets

 

Specific Scenarios

·         Internet of Things

o    Devices/MQ scenarios

o    Connecting OData and AMQP / 0MQ (zero-MQ)

·         Server-driven paging for Streaming

·         Server-driven paging for Federation

·         EDI (electronic data exchange)

 

Other Technologies

·         RDF

·         JSON-LD

·         Linked Data

 

Designing a Data Model

·         When to use complex types

·         When to use actions

·         When to use function imports vs. Entity sets

·         Open complex types for dictionaries
