  1. 1. Reactive Processes REP: A content ontology design pattern This P Monika  Solanki  and  Craig  Chapman   (versi comm {monika.solanki,  craig.chapman}   If you Birmingham  City  University,  UK   tempe day Intent Pattern Usage: Algal Biomass Production Processes Many scenarios in the engineering, manufacturing and biotechnologies As an exemplifier for the pattern, we showcase the application of REP tode sectors employ “reactive” processes, usually carried out in a closed an ontology that models algal biomass production processes. Verifour system, e.g., a bioreactor in which a chemical process is carried out, Go to which involves organisms or biochemically active substances derived prefe from such organisms. Such processes consume inputs and produce size o outputs in a controlled environment and on being triggered by certain printe events. look l The remit of the REactor Pattern (REP) is to enable the evalu ontological modelling of reactive processes in a generic way As illustrated in the Figure above, the set of inputs to the process of algal subm across multiple domains. Reactive processes are parametric where biomass cultivation are Carbon, water, total infrastructure area, total energy, nutrients, consumables and labour. Possible outputs from the the governing parameters are process inputs and outputs. REP is especially Using targeted towards modelling reactive processes with a “black box” view of process are algal constituent products, indirect algal products, uncaptured To ad the process. REP provides ontological placeholders for input and output gas emission, liquid waste output, solid waste output. Some environmental conditions that must hold for the algae to be harvested are, and t parameters, environmental conditions and events.

This effectively caters for exposing a black box and t view of the process, which is very desirable when querying the model forter to consumption and production logistics of the process.
