The catalyst sample being characterized is linked via evaluated_entity. The analytical protocol is linked via realized_plan using a CharacterizationTechnique instance. The instrument used is linked via carried_out_by as a Device. The specific technique type is expressed via rdf_type using an ontology term (e.g. CHMO:0000158 for powder XRD, CHMO:0000404 for XPS), following DCAT-AP-PLUS Pattern 3 — exactly as NMRSpectroscopy uses rdf_type: CHMO:0000613.	no

ChemicalSubstance	A MaterialEntity of constant composition, composed of chemical entities of the same type or of different types.	no
MaterialEntity	A material is an Entity that has some portion of matter as proper part.	no
FixedBedReactor	Fixed bed reactor — a tubular reactor packed with a stationary catalyst bed. The most common reactor type in heterogeneous catalysis testing.	no
LicenseDocument	See DCAT-AP specs:LicenseDocument	no
Reaction	An EvaluatedActivity representing the catalytic reaction being studied. Reaction is NOT a DataGeneratingActivity — it is the catalytic process being observed, not the process that generates the dataset. A CatalysisDataset is linked to the Reaction it is about via is_about_activity. For operando experiments (e.g. in-situ XRD during a reaction), the dataset carries both: was_generated_by: Characterization (the measurement producing data) is_about_activity: Reaction (the catalytic process being monitored) The reactor is linked via carried_out_by as a ReactorDesignType (Device). Reactants are linked via had_input_entity. The type of catalytic reaction (e.g. ammonia synthesis, CO oxidation) is expressed via rdf_type using a voc4cat or ChemO term.	no
Catalyst	A ChemicalSubstance or MaterialEntity that initiates or accelerates a ChemicalReaction without itself being affected.	no
MaterialSample	A Sample that was derived from a previous MaterialSample or some other kind of MaterialEntity.	no
ChemicalReaction	A process that leads to the transformation of one set of chemical substances to another.	no
SlurryReactor	Slurry reactor — a three-phase reactor in which catalyst particles are suspended in a liquid phase through which gas is bubbled.	no
AgenticEntity	An entity that is somehow responsible for an Activity to take place.	no
Document	See DCAT-AP specs:Document	no
Simulation	A DataGeneratingActivity in which a catalyst, catalytic material, or catalytic process is modelled computationally. The simulation software is linked via carried_out_by as a Software agent. The simulation method (protocol) is linked via realized_plan using a SimulationMethod instance. The catalyst model or reaction being simulated is linked via evaluated_entity or evaluated_activity. The specific simulation type is expressed via rdf_type (e.g. coremeta4cat:DFT, NCIT:C18097 for molecular dynamics), following DCAT-AP-PLUS Pattern 3.	no
EvaluatedActivity	An activity or process that is being evaluated in a DataGeneratingActivity.	no
ReactorDesignType	Abstract Device representing the type of reactor used in a catalytic experiment. Concrete subclasses specify the reactor geometry and operating mode. Linked from Reaction via carried_out_by.	no
ChemicalEntity	Any constitutionally or isotopically distinct atom, molecule, ion, ion pair, radical, radical ion, complex, conformer etc., identifiable as a separately distinguishable entity.	no
CatalysisDataset	A dcat:Dataset that contains research data in the field of catalysis. The catalysis research field is expressed via rdf_type using a voc4cat term from CatalysisResearchFieldEnum (following DCAT-AP-PLUS Pattern 3). For example, a dataset from heterogeneous catalysis research would carry: rdf_type: id: VOC4CAT:0007001 title: "heterogeneous catalysis" The four CoreMeta4Cat minimum information pillars are linked via the slots below, each pointing to the corresponding DataGeneratingActivity or EvaluatedActivity subclass defined in the CoreMeta4Cat subprofile modules.	no
Dataset	A collection of data, published or curated by a single agent, and available for access or download in one or more representations.	no
