Seven years ago we published OData 4.0 as a set of OASIS Standards – now we have the next incremental, fully compatible “release”: the OData 4.01 specifications – Core, JSON Data, JSON Metadata, and XML Metadata – are approved as OASIS Standards and have been published.
- Mass operations for A2A use cases, e.g. array upsert
- Alignment with REST API best practices, e.g. key-as-segment
- Alternate keys: useful for our Domain Model Alignment
OData JSON Format 4.01 is a fully compatible set of extensions to the data format, most prominent extensions are
- JSON Batch format – no more complicated multipart/mixed format – already implemented by our SAP Cloud Application Programming Model for Node.js
- Simplified delta format: useful for our Mobile Offline clients
OData CSDL ($metadata) JSON 4.01
- JSON representation of $metadata – no XML needed any more ?
OData CSDL ($metadata) XML 4.01
- Improved annotation language for UI use cases
See What’s New in OData Version 4.01 for a complete list of changes.
So what’s next?
- A new iteration of the Extension for Data Aggregation is planned for this year
- Additions to the Standard Vocabularies which form the basis for our SAP Vocabularies extensively used by SAP Fiori Elements
- An Extension for Temporal Data, useful for our Domain Model Alignment
