1. Model: Astronomical Coordinates and Coordinate Systems (coords)

Authors : Arnold Rots, Mark Cresitello-Dittmar
Date : 2017-10-10T18:16:20
Version : 2.0
Previous version: : 0.x
Abstract : The coordsys model defines a pattern for Coordinate Frame specifications, various Coordinate System objects for bundling Coordinate Frames into associated groups, and implements the CoordFrame pattern for several physical domains. The expectation is that as models are created which touch on domains not represented here, they will implement this pattern in the same fashion for the new domain. This implementation may reside in the other model, or be added to this list of implementations. Models which refer to the CoordFrame of this model are stating an expectation that the instances included follow the specified pattern.
Diagram : The following diagram has been generated from the model using the GraphViz tool.
The classes and packages in the diagram can be clicked and are mapped to the descriptions of the corresponding element elsewhere in the document.

2.Model contents: Packages and Types

2.2 package: domain

vodml-id domain
description The Domain package contains implementations of the Coordinate Frame pattern for various physical domains. Many of these domains are 1-Dimensional and there is a good deal of consolidation which could take place in those domains (ie 1-1 relations could get absorbed or eliminated). However, the defined pattern satisfies ALL domains, and we feel the consistancy this generates simplifies the understanding and implementation of the model. If one understands the pattern, the interpretation of any domain is straight-forward.

3.Element Identifiers/VO-DMLrefs

The following table shows all fully qualified vodml-ids for this data model. It is ordered alphabetically and the identifiers are hyper-linked to the location in the document where the actual element is fully defined.
vodml-id feature type description
vo-dml:model The coordsys model defines a pattern for Coordinate Frame specifications, various Coordinate System objects for bundling Coordinate Frames into associated groups, and implements the CoordFrame pattern for several physical domains. The expectation is that as models are created which touch on domains not represented here, they will implement this pattern in the same fashion for the new domain. This implementation may reside in the other model, or be added to this list of implementations. Models which refer to the CoordFrame of this model are stating an expectation that the instances included follow the specified pattern.
AstroCoordSystem objectType AstroCoordSystem is a container object for organizing physical Coordinate Frame specifications into related groupings. The object provides a references to Coordinate Frame instances in each of the known domain implementations. As a whole, the AstroCoordSystem should provide a complete description of the domain space.

domain package The Domain package contains implementations of the Coordinate Frame pattern for various physical domains. Many of these domains are 1-Dimensional and there is a good deal of consolidation which could take place in those domains (ie 1-1 relations could get absorbed or eliminated). However, the defined pattern satisfies ALL domains, and we feel the consistancy this generates simplifies the understanding and implementation of the model. If one understands the pattern, the interpretation of any domain is straight-forward.
domain.generic package Implementation of the Coordinate Frame pattern for 'generic' domains. The generic domain covers any domain not represented by the specialized physical domains, and a specialized representation is not deemed necessary.

4.Imported Models

This section lists the external models imported by the current data model. For each imported model we list URLs to the VO-DML and HTML representations and the prefix used for vodml-ids from inside the model.
