Data Query

[KathiSchleidt]

Allow a user to query for data, applying multiple query concepts.

Query concepts:

• Spatiotemporal
• Observable Properties
• Additional OMS concepts, e.g. Observing Procedure, Host, Observer
• Indicators
• crop type, growing season, soil conditions
• Time-Series
• primary vs. Derived data
• real-time data
• experimental data from research projects (e.g. Long term soil experiments)
• predicted data on soil properties
• co-located measurements (see UC2/US1 Find and access earth observation satellite data from neighbour countries for SOC model)
• persons, project name, institute
• data producer
• target group
• management practices
• filtering between knowledge records and data records

This list of query concepts should be easily extendable.

Requirements to GUI:

• Query integrating relations from vocabularies and knowledge (e.g. including narrower terms and synonyms)
• GUI should adjust to what concepts a user is requesting
• Additional filters should only be offered if suitable to the found datasets
• Make it possible to tailor content of overview to specific communities
