Features

The data services API (hm may have some minor divergence in naming here) projects a regularized view of data from an RDF graph which can be efficiently discovered, introspected and filtered. For naturally regular data such as a Data Cube then it should be sufficiently to point to the DSD to get a fully functional API. It should also be possible to create a regular view over the data by specifying a pseudo-DSD, including support for path expressions.

The key pieces of capability that will be incrementally added are:

• basic dataset list and structure description
• base data query API
• diagnostic pathway to enable a detailed trace of processing to be obtained for debug
• navigation of hierarchical aspects (aka codelist API)
• text search
• geo queries
• temporal queries
• metrics to enable query optimization
• caching

The first real sprint Sprint 2 touches the first three of these.
