1. Model: STC2 Coordinate System model (coordsys)

Authors : Arnold Rots, Mark Cresitello-Dittmar
Date : 2017-04-11T15:52:11
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

The following sub-sections present all packages in the model with their types. The packages are listed here in alphabetical order. Each sub-section contains a description of the package and a table containing its various features.

2.1.1 objectType: AstroCoordSystem

vodml-id AstroCoordSystem
description 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.

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.

CoordSys objectType The CoordSys object is the parent of a set of containers for organizing Coordinate Frame specifications into related groupings.
CoordSys.genericFrame reference TODO : Missing description : please, update your UML model asap.
PixelCoordSystem objectType The PixelCoordSystem contains the complete list of Pixel Frame specifications. Here, the relation between the system and its frames is different than in the physical CoordSys. In the pixel domain, there is only 1 system, composed of a specific set of PixelAxes organized in PixelFrames.
PixelCoordSystem.pixelFrame composition TODO : Missing description : please, update your UML model asap.
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.
