- Environmental Scientist: An active role, which is a person who conducts research or performs scientific investigations. Using knowledge of various scientific disciplines, they may collect, process, analyse, synthesize, study, report, and/or recommend action based on data derived from measurements or observations of (for example) air, rock, soil, water, nature, and other sources.
- Sensor: A passive role, which is a converter that measures a physical quantity and converts it into a signal which can be read by an observer or by an (electronic) instrument.
- Sensor network: A passive role, which is a network consisting of distributed autonomous sensors to monitor physical or environmental conditions.
- Measurement Model Designer: An active role, which is a person who designs the measurements and monitoring models based on the requirements of environmental scientists.
- Technician: An active role, which is a person who develops and deploys sensor instruments, establishing and testing the sensor network, operating, maintaining, monitoring and repairing the observatory hardware.
- Measurer: An active role, which is a person who determines the ratio of a physical quantity (such as a length, time, temperature etc.), to a unit of measurement (such as the meter, second or degree Celsius).
- Observer: An active role, which is a person who receives knowledge of the outside world through his senses, or records data using scientific instruments.
- Data collector: Active or passive role, adopted by a person or an instrument collecting data.
- Data Acquisition Subystem: In the Science Viewpoint, the data acquisition subsystem is passive role of the data acquisition community. It is the part of the research infrastructure providing functionalities to automate the process of data acquisition.

- Data Curator: An active role, which is a person who verifies the quality of the data; annotates the data; catalogues, preserves and maintains the data as a resource; and prepares various required data products.
- Semantic Curator: An active role, which is a person who designs and maintains local and global conceptual models and uses those models to annotate the data and metadata.
- Storage Administrator: An active role, which is a person who has the responsibilities to design data storage, tune queries, perform backup and recovery operations, set up RAID mirrored arrays, and make sure drive space is available for the network.
- PID Manager: A passive role, a system or service that assigns persistent global unique identifiers to data and metadata products. The Manager invokes a external entity, the PID Service, to obtain the PIDs. The manager maintains a local catalogue of PIDs that are being used to reference data and metadata. If the data or metadata in the RI change location or are removed, the PID manager updates this information locally and informs the PID Service.
- PID Service: A passive role, a public system or service which can generate and assign persistent global unique identifiers (PIDs). The PID Service also maintains a public registry of PIDs for digital objects.
- Storage System: A passive role, which includes memory, components, devices and media that retain data and metadata for an interval of time.
- Catalogue System: A passive role, a catalogue system is a special type of storage system designed to support building logical structures for classifying data and metadata.
Data Curation Subsystem: the data curation subsystem is a passive role of the data curation community. It is the part of the research infrastructure which stores, manages and ensures access to all persistent data and metadata produced within the infrastructure.
정보 title Note PID Service was called PID Generator, howerver, the analysis of the Identification and Citation practices made evident that the generation can be done inside the RI (by PID Manager), shared between the RI and the PID Service, or completely delegated to a PID Service. Consequently the names were changed after version 2.1 of the ENVRI RM.
The PID generator does not disappear completely, it is a refinement (specialisation/subclass) which can be implemented by PID service or the PID Manager

- Data Originator: Either an active or a passive role, which provides the digital material to be made available for public access.
- Data Repository: A passive role, which is a facility for the deposition of published data.
Semantic Mediator: A passive role, which is a system or middleware facilitating semantic mapping (i.e., executing mapping and translation rules), discovery and integration of heterogeneous data.
- Data Publisher: An active role, is a person in charge of supervising the data publishing processes.
Data Publishing Subsystem: In the Science Viewpoint, the data publishing subsystem represents a passive role of the data publication community. It is the part of the research infrastructure enabling the discovery and retrieval of scientific data. The access to this subsystem could require authorisation at different levels for different roles.
- Data Consumer: Either an active or a passive role, which is an entity who receives and uses the data.
- Metadata Harvester: A pasive role, which is a system or service collecting metadata which supports the construction/selection of a global conceptual model and the production of mapping rules

- Data Provider: Either an active or a passive role, which is an entity providing the data to be used.
- Service: A passive role, in which a functionality for processing data is made available for general use.
- Service Consumer: Either an active or a passive role, which is an entity using the services provided.
- Service Provider: Either an active or a passive role, which is an entity providing the services to be used.
- Service Registry: A passive role, which is an information system for registering services.
- Capacity Manager: An active role, which is a person who manages and ensures that the IT capacity meets current and future business requirements in a cost-effective manner.
- Data Processing Subsystem: In the Science Viewpoint, the data processing subsystem represents a passive role of the data processing community. It is the part of the research infrastructure providing services for data processing. These services could require authorisation at different levels for different roles.
- Processing Environment Planner: An active agent that plans how to optimally manage and execute a data processing activity using RI services and the underlying e-infrastructure resources (handling sub-activities such as data staging, data analysis/mining and result retrieval).
