PMD Core Ontology
## All DBpedia Archivo ontologies from w3id.org domain Each artifact in this group deals as the archive for snapshots of one ontology of the [DBpedia Archivo](https://databus.dbpedia.org/ontologies) - A Web-Scale Interface for Ontology Archiving under Consumer-oriented Aspects. Find out more at [http://archivo.dbpedia.org](http://archivo.dbpedia.org). The description for the individual files in the artifact can be found [here](http://dev.dbpedia.org/DBpedia_Archvio#files).
## DBpedia Archivo Ontology Snapshot | Attribute | Value | | - | - | | Ontology URI | <https://w3id.org/pmd/co> | Archivo Ontology Factsheet| [Link](http://archivo.dbpedia.org/info?o=https://w3id.org/pmd/co) | Snapshot File URL | <https://materialdigital.github.io/core-ontology/ontology.owl> | Snapshot OWL Version IRI | <https://w3id.org/pmd/co/3.0.0-alpha3> | Snapshot Time | 2025-10-19 21:56:42 The [DBpedia Archivo Databus agent](https://databus.dbpedia.org/ontologies) generates only basic, static documentation for the archived snapshots of the ontologies. ## Ontology Metadata DBpedia Archivo extracts metadata from the ontology for well known properties (e.g. dct:description). This subsection shows the content of every property individually using a separate heading. ### dct:description 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. 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.
