Matter transfer

The Matter Transfer ontology (TRANSMAT) is dedicated to matter transfer (eg O2, CO2, H2O) and mechanical properties of materials (eg food, packaging). MAPOPT is divided into three parts:

The tab Ontology gives an overview of data structuration in order to help with global understanding and list the topics available in the tab Documents associated with this ontology
The tab Documents gives access to a database collecting the information then structured by the ontology. Original papers and associated annotated tables (packaging O2/CO2 permeability, food product O2/CO2 solubility/diffusivity) are available through this tab.
The tab Query allows to extract annotated data by defining research criteria (material type, temperature range, etc.).

Data available on this ontology concern material characterization (packaging O2/CO2/H2O permeability and mechanical properties, food product O2/CO2 solubility/diffusivity, etc.).

Data are structured around:

Symbolic concepts including studied objects and qualitative data: material type, molecule type, etc.
Quantity concepts including quantitative data: temperature, packaging thickness, relative humidity, etc.
Relation concepts describing relationships between studied objects, qualitative and quantitative data: O2permeability relation, volatil solubility Young's modulus relation, etc.

A relation concept is characterized by its label and its arguments; it can have several inputs but only one output. All inputs and outputs are related either to symbolic or quantity concepts.

Exemple transmat — The relation concept which represents the O2 permeability measure and associated controlled parameters

For instance, the O2 permeability relation describes the O2 permeability measure and its associated controlled parameters required fur reusability.

The entire set of relation concepts aims to model data associated with matter transfer and mechanical properties of materials (eg food, packaging).

An overview of this set is available on @Web (Ontology -> TRANSMAT -> Explore).

Each concept is individually accessible through Ontology -> TRANSMAT -> View.
