Common use of Data Model Clause in Contracts

Data Model. ‌ ODV introduces a new data model and storage format, suitable for marine and other environmental profile, trajectory and time-series data. Individual stations in a data collection are described by a set of metadata. There is a minimum set of mandatory metadata, including cruise and station names, longitude, latitude as well as date and time. In addition, users may specify an arbitrary number of optional string or numeric metadata. Except for longitude and latitude, all other metadata values may be missing. As for metadata variables, the number of data variables (e.g., the variables holding the actual data) in ODV collections is unlimited, and the value types may be numeric or string. ODV supports a variety of numeric metadata and data variable value types ranging between single-byte integers and 8-byte double-precision real numbers. Quality flag values of metadata and data variables can be encoded using one of the supported 16 popular quality flag schemes in the community. ODV lets you subset and filter stations as well as samples, and provides separate sets of station and sample selection criteria. Every data window now uses its own sample filter, and filtering can be by quality flags and/or value ranges (numeric ranges or string wildcard expressions). Newly created ODV collections use the new data model and file storage format. ODV data collections are platform independent, and may be transferred between all supported systems.‌
