Structure of this Document The remaining sections of this document identify and briefly describe the relevant standards and discuss some wider considerations. They are: • Representation Standards – dealing with how information is represented as data at a fundamental level in data sets and APIs These standards can apply to source data, integrated data, and contextual metadata. • Structure Standards – dealing with how data is structured in data sets and APIs These standards also can apply to source data, integrated data, and contextual metadata. • API Standards – dealing with additional considerations where data is obtained from or posted to APIs, rather than being read from or written to data sets • Metadata Standards – applying mainly to contextual metadata but in some cases also to metadata included in source data or integrated data • Data Analysis and Transformation Standards – applying to software components that perform analysis or transformation • Wider Considerations for Data Integration Standards – discussing some existing standards and best practices that might be relevant, and new standards work that might be useful in relation to non-technical aspects of data integration
