A record is an XML metadata document conforming to a named SeaDataNet schema describing a particular type of SeaDataNet data entity.
A meaningful collection of measurements. 'Meaningful' can have infinite different meanings that must be constrained through the definition of specific types of dataset used within the SeaDataNet data model. The following dataset types are in use:
Common Data Index (CDI) Dataset
This is the fundamental atomic entity in the SeaDataNet data model and is an aggregation of measurements or observations. It is mapped to real world measurement aggregations in different ways such that the dataset is meaningful for a specific type of data, such as a CTD profile or the time series from a single deployment of a data logger. It is described by a CDI record that is permanently associated in the SeaDataNet architecture with one or more physical data files.
This is the aggregation of CDI datasets from the activity described by a Cruise Summary Report (CSR) record.
This is the aggregation of CDI datasets from a discoverable activity described by a European Directory of Marine Environmental Datasets (EDMED) record.
This is the aggregation of CDI from a monitoring activity described by an EDIOS series record. This is the atomic level of monitoring activity such as a station within a programme.
EDIOS Programme Dataset
This is the aggregation of a set of related EDIOS datasets and is described by an EDIOS programme record. Note that an EDIOS programme dataset may also be considered to be a discoverable activity and additionally described by an EDMED record.
This is the aggregation of the CDI datasets from an activity described by a European Directory of Marine Environmental Research Projects (EDMERP) record.
This is an aggregation of CDI datasets that provide the input for a SeaDataNet or EMODNET data product, such as a climatology or location time series. The aggregation will be usually be specified in terms of spatio-temporal limits and one or more observable properties (parameters).
This is a CDI aggregation guaranteed free from future change that is citable through a URN such as a Digital Object Identifier (DOI).
This is the aggregation of CDI data granules having a common data discovery parameter keyword supplied by a single data originator. It is the dataset presented to the GI-Cat brokering service.
This is the aggregation of all the CDI datasets in the SeaDataNet system.
