189 This document provides a data model describing the structure and content of generic Dataset metadata for the IVOA. This is
190 a high-level model which is to be referenced and extended by other models describing specific types of Datasets and Data products.
191 In this document, we specify the generic Dataset, as well as an ObservationDataset model which covers the class of Datasets
192 which are derived from an Observation. At the time of this writing, there is no formal Observation-Experiment model for the
193 IVOA, so we include a hypothetical Observation-Experiment model to serve as a placeholder.

301 This Characterisation object is a direct extension of the Characterisation object from the IVOA Characterisation Data Model
302 Standard. This provides a local object which may be contained in a 'composition' relation to other objects of this model
303 (specifically ObsDataset). This object may be extended and/or modified by specific Dataset models as needed.
304 Characterisation provides a broad scale description of the coordinate space occupied by the dataset in each of the axis domains.
305 This includes axes not directly represented in the dataset 'data', for example, the Time axis of a 2D special image. As such,
306 there is a strong correlation between Characterisation and Data objects. In some cases, the values may be directly derived
307 from the Data, in others, they provide supporting metadata about the broader domain. For example, the Accuracy fields in
308 Characterisation represent typical accuracy for the dataset, while those within Data provide per-data-point errors.

1708 Scale:
1709 * 0 - Raw instrumental data, in a proprietary or internal data-provider defined format.
1710 * 1 - Instrumental data in a standard format (FITS, VOTable, etc )
1711 * 2 - Calibrated, science ready data with the instrument signature removed.
1712 * 3 - Enhanced data products like mosaics, resampled or drizzled images, or heavily processed survey fields. Level 3 data
1713 products may represent the combination of data from multiple primary observations.

2074 The Observation Experiment model refers to several elements related to an Observation and its configuration. As of the time
2075 of this writing, there is no IVOA recommendation for a general Observation data model. The Provenance data model, in progress,
2076 will define the pattern for describing the relation between actions and results, and how to record these in datasets. In
2077 lieu of these standards, this document defines a straw-man Observation model.
2078
2079 The Observation is modeled as a type of 'Experiment', with some basic structure defined to provide metadata about the observation
2080 target and configuration. The product, or 'result' of the Observation is zero or more ObsDataset objects. This pattern is
2081 inspired by, and compatible with the Simulation Data Model, where a 'Simulation' can be considered another form of 'Experiment'
2082 or perhaps even another form of 'Observation'.
