Main schema for ESPAS core catalogue metadata. Describes datasets at a high-level in terms of the type of acquisitions made, instrutments used, parameters observed etc. Does not contain detailed time-sensitive information about precise acquisitons (e.g. position and time of particular observations (real or virtual)). This is the subject of the 'Acquisitions' extension schema. -- Name -- OnlineService -- Definition -- A reference to any type of online service. -- Description -- Used to declare the existence of an online service for the dataset.

It realises 19115 MD_Metadata It is used to describe a set, or collection, of data (which may be made up of many individual data records or products). It descibes the dataset at a high level - which instruments, observatory etc are used, who manages the dataset etc. A dataset may belong to a wider 'Program'. A Dataset may describe multiple deployment configurations e.g. instruments on serveral different platforms and/or at observatories, or it may be made up of a single deployment configurtaion with just a single instrument. Information about specific acquisitions (for example precisely where and when measumernets were made) are modelled as an extension to this core metadata model in the Acquisitions package. -- Name -- espasID -- Definition -- The identifier which uniquely identifies this object in the ESPAS infrastructure. -- Name -- title -- Definition -- A human-readable title for the dataset -- Name -- description -- Definition -- A paragraph describing the dataset -- Name -- dataset status -- Definition -- The status of the dataset acquisitions (historical, current, planned). -- Name -- primary geographic extent -- Definition -- The geographic extent of the acquisition.

This may be a 3D bounding box in some coordinate reference system, or it may be a single point (or various possibilities in between). NOTE: primaryGeographicExtent must be given in: a) A coordinate reference system that is acceptable within the ESPAS system b) Using a geometry type which is acceptable within the ESPAS system. **GM_Object is the base type for a whole range of geometries. An open issue for ESPAS is to agree on a defined set of suitable structures to use here from the range of possible options- e.g. BoundingBoxes, Points, Lines, Polygons etc ** -- Name -- dataset start date -- Definition -- The start date of the dataset (e..g date of first acquisition) if known. -- Name -- dataset end date -- Definition -- The end date of the dataset (e.g date of final acquisition) - if known.
