Ontology Specification Draft

Abstract

The PMD Core Ontology (PMDco) is a comprehensive framework for representing knowledge that encompasses fundamental concepts from the domains of materials science and engineering (MSE). The PMDco has been designed as a mid-level ontology to establish a connection between specific MSE application ontologies and the domain neutral concepts found in established top-level ontologies. The primary goal of the PMDco is to promote interoperability between diverse domains. PMDco's class structure is both understandable and extensible, making it an efficient tool for organizing MSE knowledge. It serves as a semantic intermediate layer that unifies MSE knowledge representations, enabling data and metadata to be systematically integrated on key terms within the MSE domain. With PMDco, it is possible to seamlessly trace data generation. The design of PMDco is based on the W3C Provenance Ontology (PROV-O), which provides a standard framework for capturing the generation, derivation, and attribution of resources. By building on this foundation, PMDco facilitates the integration of data from various sources and the creation of complex workflows. In summary, PMDco is a valuable tool for researchers and practitioners in the MSE domains. It provides a common language for representing and sharing knowledge, allowing for efficient collaboration and promoting interoperability between diverse domains. Its design allows for the systematic integration of data and metadata, enabling seamless traceability of data generation. Overall, PMDco is a crucial step towards a unified and comprehensive understanding of the MSE domain. PMDco at GitHub: https://github.com/materialdigital/core-ontology

A :ValueObject is a simple entity which represents a specific value. This value can be a numerical, textual, or a more complex data structure. If a literal value is to be specified, the :value datatype property has to be used. In cases where the value is represented by a resource (e.g. URI), the :resource object property has to be used. A value object, respectively its value, is always associated with an entity of type :Process, :ProcessingNode, or :Object (e.g. :Specimen). The value is meant to be a charactaristic of the associated entity. To express this association it is indended to use the :participant object property. A value object might also refer to a certain unit. The :unit property might be used (e.g. with QUDT ontology). Instances of a value object might be specified as a specific Parameter, namely a SetPoint (nominal value), or Measurement. With :Setpoint the intend is to express, that the value is meant to be some preset, setting or nominal value. :Measurement expresses, that the value has been measured or determined somehow (see example). Instances of a value object might also be specified in a specific DataScope (:Metadata, :PrimaryData, :SecondaryData).

IRI: https://w3id.org/pmd/co/PixelUnit

In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest point in an all points addressable display device. In most digital display devices, pixels are the smallest element that can be manipulated through software. Here it is referred to as a unit of counted pixels. (It is not an officially recognized unit).
