GEOSS User Requirements Registry

URR Components:

• Properties: registry of properties, that is, variables and products that are related to the Earth system’s state and trends;
• User Types: registry of GEOSS user types, groups and classes;
• Applications: registry of applications using GEOSS observations and/or products and/or producing products for other applications;
• Requirements: list of quantitative requirements for GEOSS observations and products;
• Specifications: Agreed upon specifications of system performance in terms of products and their characteristics;
• Techniques: registry of observation techniques, including the observed variables, accuracy, resolution, latency, reliability, availability, and status (research, operational);
• Observations: registry of observations available to GEOSS;
• Products: list of products (may include observations) made available through GEOSS services, including a quantitative characterization.

Link Functions:

• the linkage of applications to applications;
• the linkage of user types to applications and applications to user types;
• the linkage of applications to requirements and requirements to applications;
• the linkage of observations to products and products to observations.

Edit functions for GEO members:

• registration of user types;
• registration of applications.

Administrative Editing:

• Properties;
• Techniques;
• Requirements;
• Specifications;
• Observations;
• Products;
• All links.

Analysis functions:

• identification of deviations of system performance from specifications;
• identification of requirements not met by products and applications not receiving the required products (gaps analysis);
• identification of user types not able to utilize the full benefit of Earth observations.
