This ontology allows a thorough description of the whole data generation process (experiment, observation, simulation), embracing the object of investigation, all sample and data manipulation procedures, a summary of the data files and the information contained, and all personal and institutional roles. The subordinate classes and relations can be built according to the two principles of _inheritance_ and _modularity_. _Inheritance_ means that a subclass inherits all properties of its superordinate class, possibly adding some new ones. _Modularity_ means that all expansions are independent of each other; this makes possible for instance to generate expanded ontologies for any possible combinations of method × object of research.", "homepage" : null, "version" : "v1.4.0", "mailingList" : "metadata4ing@nfdi4ing.de", "tracker" : "https://git.rwth-aachen.de/nfdi4ing/metadata4ing/metadata4ing/-/issues", "logo" : "https://w3id.org/nfdi4ing/metadata4ing/m4i_logo.png", "creators" : [ ], "annotations" : { "references" : [ "cordi.v1i.271", "csba-e454", "tuprints-00024573", "zenodo.4846313", "IJMSO.2020.107792", "zenodo.3816686", "zenodo.3982367" ], "subject" : [ "4137304-2", "1227971389", "1342271416", "4384643-9", "4827894-4" ], "language" : [ "deu", "eng" ], "source" : [ "CoRDI.v1i.271", "zenodo.7362037", "page=6" ], "title" : [ "Metadata4Ing: An ontology for describing the generation of research data within a scientific activity." ], "repository" : [ "https://git.rwth-aachen.de/nfdi4ing/metadata4ing/metadata4ing/" ], "example" : [ "first-steps-guide.md" ], "contributor" : [ "0009-0007-2881-3125", "0000-0002-9033-5538", "0000-0003-0941-5950", "0000-0001-8341-1478", "0000-0002-2239-3955", "X", "0000-0002-2639-1949", "0000-0002-5031-9170", "0000-0002-1019-9151", "0000-0002-1698-6826", "0000-0002-1489-6501", "0000-0002-8524-0569" ], "rights" : [ "https://creativecommons.org/licenses/by/4.0/" ], "preferredNamespacePrefix" : [ "m4i" ], "modified" : [ "2025-12-10" ], "issued" : [ "2025-12-10" ], "creator" : [ "Metadata4Ing Workgroup" ], "audience" : [ "Engineers and scientists working with quantitative data", "Ingenieure und Forschende, die mit quantitativen Daten arbeiten" ], "funding" : [ "442146713" ], "created" : [ "2022-02-22" ], "replaces" : [ "1.3.1" ], "documentation" : [ "metadata4ing" ], "abstract" : [ "The ontology Metadata4Ing provides a framework for the semantic description of research data and of the whole data generation process, embracing the object of investigation, all sample and data manipulation methods and tools, the data files themselves, and the roles of persons and institutions.
