- The D4 spec is broken into two parts: The Data model and the Web services descriptions. In addition, there is a provision for extensions that cover additional behavior. Examples of likely extensions are JSON responses and Server processing operations.
- Metadata in one response
- Data model: Coverages, Groups, 64-bit integers, other types
- Checksums for all data responses
- Encoding of data responses
- Reader makes right
- reliable error delivery while returning data
- Constraints
- Subsetting coverages
- Filters are per variable
- DSR: per-dataset capabilities document; fixes an inconsistency when a 'bare URL' is dereferenced
- Asynchronous behavior
- Web services
- Defines how the protocol is used with HTTP --> implies that we've thought explicitly about using it with other protocols
- Alternate media types - content negotiation
- DSR --> HATEOS
