General description

Name:	Reactor pattern
Submitted by:	MonikaSolanki
Also Known As:
Intent:	The remit of the reactor pattern is to enable the modelling of reactive processes that consume inputs and produce outputs under specific environmental conditions and on being triggered by certain events.
Domains:
Competency Questions:	1. What are the inputs consumed by a certain process? 2. What environmental conditions need to hold for the process to get activated? 3. What are the outputs produced by the process? 4. Which event triggers a specific process? 5. What is the measurement criteria for a specific parameter?
Solution description:
Reusable OWL Building Block:	1 (586)
Consequences:	The main advantage of this pattern is that its provides ontological modelling capabilities for the inputs, outputs and environmental conditions that govern reactive processes across several domains, independent of modelling details of the actual reactor involved. This effectively caters for exposing a black box view of the process, which is very desirable when querying the model for consumption and production logistics of the process.
Scenarios:	As an exemplifier for the reactor pattern, we present a use case from the domain of algal biomass. We employ the reactor pattern in an ontology OntoMDL. The ontology models a process for algal biomass cultivation. OntoMDL implements the Minimum Descriptive Language(MDL) standard prescribed by the Algal Biomass Organisation(ABO) for algal operation. The set of descriptive metrics recommended by MDL as inputs to the process are carbon, water, total infrastructure area, total energy, nutrients, consumables and labour. Possible outputs from the process are algal constituent products, indirect algal products, uncaptured gas emission, liquid waste output, solid waste output. Some environmental conditions that must hold for the algae to be harvested are, (1)The water must be in a temperature range that will support the specific algal species being grown.(2)The pH range for most cultured algal species should be between 7 and 9, with the optimum range being 8.2-8.7. The event that triggers of the algae cultivation is the addition of the source culture to the growing containers or reactors.

The Reactor Pattern enables the modelling of processes that consume inputs and produce outputs under specific environmental conditions and on being triggered by certain events. Reactor pattern is a content ontology design pattern and is especially targeted towards modelling reactive processes with a black box view of the process.
