17 <description>UML DataType is the base class of Primitive Type and Enumeration.
18
19 This types are generic and does not represent specific implementation types.
20
21 Primitive type is a predefined datatype which does not have a structure.
22
23 ivoaIdentifier is a DataType since it has possibly a structure.

32 <description>This is the main/root package of the SNAP data model.
33 It contains the other packages, and also some classes that might be better imported from the resource model of the IVOA registry WG. However those types were deemed to be too restrictive for our purposes.
34
35 Anyway, our approach is that an instance of the SNAP datamodel can be used to generate registry rsources, for example using XSLT, but is does not have to contain resources.</description>

87 <description>The values of this type are to be used in the definition of metadata fields such as Property and InputParameter. These data types correspond to actual types used in computation and data representation and are slightly different from the more abstract types in the domain model in [2].
88 They are clearly related to similar concepts as in the DataType defined in the XML schema for VOTable.

399 <name>Characterisation</name>
400 <description>This class represents the characterisation of a property of an object in a given object collection. It represents both a priori and a posteriori characterisations. With a priori characterisation we indicate possible and/or nominal [?] values the variable may take, it defines the possible range of values of the property. In contrast, an a posteriori characterisation of a property in an object collection provides summarising, likely statistical, information on the values that were actually taken up (observed, simulated) by the objects in the collection.
401 The a priori characterisation is most similar, in fact a generalisation of the Characterisation model of the IVOA Data Model working group [3]. In the domain model in
402 In the current model we stick to simple quantities for characterising a collection of objects. For example the equivalent value of a support from [3] is absent, as it is not terribly useful for discovery and querying, even more so of course for concepts equivalent to sensitivity.
403 [TBD How relevant is it for simulations? Examples if we require it for the actual meta data specification, for example for usages beyond query and discovery.]

529 <description>This class represents a part of the universe at a particular point in time, or possibly a more general sub-volume of space-time, for example a light-cone. We realise this does not represent all possible outputs of simulations. For example some simulations of dense (collisional) stellar systems produce orbits of the individual particles, at individual output times . In general though those results can be used to produce snapshots as well (Peter Teuben, private communication). Hence for the current version of the model we propose the use of Snapshot results of simulations and other SNAPResults as well, the only exception being light-cones through cosmological simulations</description>
