  "abstract": "<p>We present here a novel approach for the definition of terminology, classification and metadata for materials characterization methods, where the main purpose is to arrive to a standard structure (that we will call CHADA) for representing materials characterization data.</p>\n\n<p>The first step towards this goal is the definition of the terminology associated to materials&rsquo; characterization methods. We propose that only four types of concepts are used for the classifications of the different steps of an entire characterisation workflow (which can be simply called &ldquo;characterisation&rdquo;):</p>\n\n<ol>\n\t<li><strong>Sample (or &ldquo;user case&rdquo;)</strong>, which represents&nbsp;<strong><em>volume</em></strong>of&nbsp;<strong><em>probed material</em></strong>, and the information on the surrounding&nbsp;<strong><em>environment</em></strong>, which interacts with the probe and generate a detectable (measurable)&nbsp;<strong><em>signal</em></strong>(information);</li>\n\t<li><strong>Method</strong>, which represents the&nbsp;<strong>process</strong>(or the sequence of processes) by which the metrological chain is defined; within a single method, the following fundamental elements are identified : user, probe, signal, detector, noise;</li>\n\t<li><strong>Raw data,&nbsp;</strong>is the set of data that is given directly as output from the metrological chain, usually expressed as a function of time;</li>\n\t<li><strong>Data processing, which represents any process (or sequence of processes) by which the</strong>data are analyzed to arrive to the final shape.</li>\n</ol>\n\n<p>By using this simplified approach, a generic characterization method can be documented by the schemes reported in the presentation, which can be used for the construction of the metadata structure of any generic material&rsquo;s characterisation process.</p>\n\n<p>In those scheme, we also define the fundamental vocabulary that describes the main elements of a characterisation experiment, which could be further refined for any specific technique.&nbsp;</p>\n\n<p>Since all standardized characterization methodologies consists, in practice, of a well-defined sequence of items and actions, the same approach can be used to develop a generic workflow program.&nbsp;&nbsp;This scheme is also based on a similar concept developed within the European Materials Modelling Council (MODA,&nbsp;<a href=\"https://emmc.info/moda/\">https://emmc.info/moda/</a>), where the data from a generic model are represented according to the representations of User Case, Model, raw outputs and processed outputs.</p>",
