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

360            <body>The Observation Experiment model refers to several elements related to an Observation and its configuration.  As of the time of this writing, there is no IVOA recommendation for a general Observation data model.  The Provenance data model, in progress, will define the pattern for describing the relation between actions and results, and how to record these in datasets.  In lieu of these standards, this document defines a straw-man Observation model.  
361    
362  name:  A string describing the spectral range.  This field corresponds to both the Coverage.Spectral and Coverage.Spectral.Bandpass fields of the Resource Metadata document.  The value may be any one of the strings listed for Coverage.Spectral (e.g. "Optical") or Coverage.Spectral.BandPass (e.g. "B").  Note that at this time, there is no fixed list of values for this latter group.  The Observation is modeled as a type of 'Experiment', with some basic structure defined to provide metadata about the observation target and configuration.  The product, or 'result' of the Observation is zero or more ObsDataset objects.  This pattern is inspired by, and compatible with the Simulation Data Model, where a 'Simulation' can be considered another form of 'Experiment' or perhaps even another form of 'Observation'.

377              <body>Describes the spectral range of the observation.  The value may be expressed in terms
378    of general spectral bands, or specific bandpass names.  If multiple bands are covered, the value
379    may be a comma delimited combination of appropriate bands.  If expressed as general bands,
380    the value(s) must be selected from the enumerated set given by the SpectralBand type.  There is
381    no controlled vocabulary for bandpass names as the list is too long to enumerate.  Effort should
382    be made to use highly recognized bandpass names (eg: "U","V","B","R","I", "H-alpha").
383    This field corresponds to both the Coverage.Spectral and Coverage.Spectral.Bandpass fields of
384    the Resource Metadata document.

692                <body>The target name.  The primary purpose of this field is to provide the user with a recognizable identity of the particular subject or goal.  However, since this may be a query-able field in data discovery protocols, care should be taken to use values which follow conventions for the domain appropriate for the data.  For an astronomical object, this may be a name suitable for use within a domain-specific resolution service.  Simulated data might also use this sort of name (if simulating a particular object), or a more generic term such as "G2V star".

869              <body>Describes the original source of the data in a very general fashion.  In other words, "What sort of observation originally generated the data?"  Suggested values include:
870    * survey: Survey data typically covers some region of observational parameter space with as complete as possible coverage within that region.
871    * pointed:  Pointed data of a particular object or field.
872    * theory:  Theory data, generated based on a theoretical model.
873    * artificial:  Artificial, or simulated data.  Similar to 'theory', but not necessarily based on a theoretical model.
874    * custom:  Custom data, as part of a specific research project.

1536                <body>IVOA dataset identifier assigned by the publisher to uniquely identify the dataset within its holdings.  Typically, the basis of this identifier will be the publisher ID.  However, if the publisherchooses to use a 'global index service' such as ADS to obtain persistent identifiers for their datasets, rather than generate their own, that identifier should be used both here and for DataID.datasetID.  Note: this model also defines a creator dataset ID (DataID.creatorDID), these will differ if the publishing entity is not the creator of the dataset.  Values are to be expressed as dataset identifiers using the syntax described in "IVOA Identifiers"</body>

1715              <body>The Derived (short for Derived Data) object holds derived information obtained by evaluating or analyzing the contents of the dataset.  The specific content of this object is strongly dependent on the specific type of dataset, so we provide a generic model which may be specialized in other models to define elements appropriate for that type of dataset.
1716    
1717    The primary purpose of this object is to provide a common framework in which specific information may be placed to aid in discovery and filtering of datasets in various access protocols.

2135    Scale:
2136    * 0 - Raw instrumental data, in a proprietary or internal data-provider defined format.
2137    * 1 - Instrumental data in a standard format (FITS, VOTable, etc )
2138    * 2 - Calibrated, science ready data with the instrument signature removed.
2139    * 3 - Enhanced data products like mosaics, resampled or drizzled images, or heavily processed survey fields.  Level 3 data products may represent the combination of data from multiple primary observations.

2262              <body>Abstract base for defining derived data elements.  Typically, models for specific data products would extend this object to define various elements appropriate for that model.  For example, the Spectrum model could define signal-to-noise ratio (SNR), or TimeSeries could define period, or variability.  We put no restriction on the DerivedElement content since the result could be a simple value or a complex object.  However, it is recommended that extensions be simple and compact in keeping with the primary intent of use in data discovery.
