Allows for independent descriptions of the components that can be linked and re-used by various configurations Example: MVCO: Owner and operator contact information. List of and links to four major components of the observatory. 12_m_node: Position information and coordinate reference system. List of and links to instrumentation associated with 12-m node. RDI_Workhorse_1200: A general description of the Teledyne RDI Workhorse Model Technical specifications and system characteristics for this model. Manufacturer and technical point of contact information. MVCO_Workhorse_1200: Description entailing details about the specific MVCO instance of a Teledyne RDI Workhorse Model 1200 and the ProcessModels that operate on individual data points. Describes the set up at the MVCO and specifies particulars, like sampling frequency, reporting frequency, and burst length. It also refers to operational points of contact and time-stamped service events that occur which may affect the quality of your observation (like a failed pressure port and its replacement, or a cleaned ADCP face).
