The IV of the ENVRI RM defines two main types of information objects: Data and Metadata.
Information objects are used to model the various types of data and metadata manipulated by the RI. The IV information objects can be grouped as follows.
- Data: research data processed by the RI:
- Persistent data data
- Unique identifiers for the data identification
- Backup (of data)
- Metadata: data typically related to the design of observation and measurement models, complements data by providing more precise details.
- Design specification of the observation and measurement
- Description of the measurement procedure
- Quality Assurance (QA) annotations
- Concepts from a conceptual model, e.g. an ontology
- Mapping rules which are used for the model-to-model transformations
- Provenance records
- Management metadata (The data used to identify the states of data and metadata objects)
