AP233-DIS Ontology

This is a Protege version 4.0 OWL file. Its the very beginnings of a reference data collection for AP233. It is unreviewed work in progress by Harry Frisch. I'm using AP239 DEXlib reference data work as a creation guide. I'm using AP233 documentation layout constructs to aid in making the product reviewable in logically connected chunks. I'm using readilly available systems engineering standards for semanics. In priority order: ISO 15288, INCOSE Systems Engineering Handbook v3.1 5-Sep-2007, Navy SE-Guide-for-SoS, NASA-2007 SE HandbookRev1. The struggle is to maintain a consistent level of abstraction across the whole. Suggestion would be appreciated.

It stimulates the development of the requirements and architecture related to the user elements of the system.

The system-of-interest may be a prototype in this stage. The hardware, software and operator interfaces are specified, analyzed, designed, fabricated, integrated, tested and evaluated, as applicable, and the requirements for production, training, and support facilities are defined. This stage also ensures that the aspects of future stages (production, utilization, support, and retirement) and their enabling systems&#39; requirements and capabilities are considered and incorporated into the design through the involvement of all interested parties. Feedback is obtained from stakeholders and those who will produce, operate, use, support, and retire the system-of-interest. Outputs are a system-of-interest or a prototype of the final system-of-interest, refined enabling systems or the enabling systems themselves and all documentation and cost estimates of future stages.

The Development Stage is executed to develop a system-of-interest that meets acquirer requirements and can be produced, tested, evaluated, operated, supported and retired.</rdfs:comment>

NOTE     A requirment is a statement that identifies a system, product or process&#8217; characteristic or constraint, which is unambiguous, clear, unique, consistent, stand-alone (not grouped), and verifiable, and is deemed necessary for stakeholder acceptability.

Pseudostates are typically used to connect multiple transitions into more complex state transitions paths. For example, by  combining a transition entering a fork pseudostate with a set of transitions exiting the fork pseudostate, we get a  compound transition that leads to a set of orthogonal target states.</rdfs:comment>

If more than one of the guards evaluates to true, an arbitrary one is selected. If none of the guards evaluates to true, then the model is considered ill-formed. (To avoid this, it is recommended to define one outgoing transition with the predefined &#8220;else&#8221; guard for every choice vertex.)

Conversely, they can be used to split an incoming transition into multiple outgoing transition segments with different guard conditions. This realizes a static conditional branch. (In the latter case, outgoing transitions whose guard conditions evaluate to false are disabled. A predefined guard denoted &#8220;else&#8221; may be defined for at most one outgoing transition.

The focus is just as much on content as on being reviewable on logical chunks

Use layout constructs within AP233 ISO documentation for logical chunking.
Use layout constructs within AP239 DEXlib reference data as a guide.

Semantics and definitions of AP233 reference data based upon:
     1 - ISO-15288 standard
     2 - INCOSE Systems Engineering Handbook v3.1 5-Sep-2007
     3 - Ap233 Concept model Draft 12
     4 - Navy SE-Guide-for-SoS
     5 - NASA-2007 SE HandbookRev1

Attempts to remove redundancy and synonyms have been made; the above  list order aligns with prioritization.</dc:description>
