no |

| InfraredSpectroscopy | Infrared spectroscopy (FTIR/ATR) for functional group and surface species identification. | no |
| Piezoelectricity | Piezoelectric response of a non-centrosymmetric material, described by the piezoelectric tensor. Relevant for piezocatalysis applications. |
no |
| CombustionSynthesis | Catalyst preparation by combustion of a fuel/oxidizer mixture, producing metal oxide catalysts in a single rapid step. |
no |
| SupportiveEntity | The supportive entities are supporting the main entities in the Application Profile. They are included in the Application Profile because they form the range of properties. | no |
| Microreactor | Microreactor — a miniaturised flow reactor with characteristic dimensions in the sub-millimetre range, enabling precise thermal control and rapid screening. |
no |

no |
| Policy | See DCAT-AP specs:Policy | no |
| DepositionPrecipitation | Catalyst preparation by deposition-precipitation: the active phase is precipitated directly onto the support surface. |
no |
| Duration | A quantitative measure of elapsed time (duration of a process step). | no |
| CatalysisDataGeneratingActivity | A CoreMeta4Cat specialization of DCAT-AP-PLUS's DataGeneratingActivity that adds a type designator (activity_designator). Synthesis, Characterization, and Simulation all specialize this class instead of DataGeneratingActivity directly, so that when one of them is nested inside CatalysisDataset.was_generated_by, the LinkML Python loader can tell which concrete subclass a given entry is meant to be and keep its subclass-specific fields (e.g. Characterization.realized_plan) rather than falling back to DataGeneratingActivity's own generic slot definitions. activity_designator is filled in automatically by LinkML when a class is instantiated directly (e.g. loading a standalone Synthesis-NNN.yaml file) -- it does not need to be set by hand there. It only needs to be set explicitly in the source data when a Synthesis/Characterization/ Simulation instance is nested inside another object's was_generated_by list (e.g. in a combined CatalysisDataset file), so the loader knows which of the three to construct. |

| CatalyticReaction | A ChemicalReaction (chemdcat-ap) specialization representing the catalytic reaction being studied. Inherits the generic reaction slots (starting materials, reactants, products, catalyst, solvent, reactor, temperature, pressure, yield, reaction steps) from ChemicalReaction and adds catalysis-specific operating-condition slots. 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 the inherited used_reactor slot (is_a: carried_out_by), narrowed here to require a ChemicalReactor instance rather than touching the generic carried_out_by relation directly. Reactants are linked via the inherited used_reactant slot (range: Reagent) -- CatalyticReaction does not declare its own reactant slot. The type of catalytic reaction (e.g. ammonia synthesis, CO oxidation) is expressed via rdf_type using a voc4cat or ChemO term. |

| ChemicalEntity | Any constitutionally or isotopically distinct atom, molecule, ion, ion pair, radical, radical ion, complex, conformer etc., identifiable as a separately distinguishable entity. | no |
| SubstanceSampleCharacterizationDataset | A Dataset about a SubstanceSample that was produced by a SubstanceSampleCharacterization activity. This is a coarse-grained convenience shape that conflates measurement and analysis into a single data-generating activity.

no |
| Precursor | A MaterialSample that serves as input material in a catalyst Synthesis. Precursors are consumed or transformed during the preparation process. |
no |
| DataAnalysis | An Activity that evaluates the data produced by another Activity. | no |
| CatalysisPlan | A CoreMeta4Cat specialization of DCAT-AP-PLUS's Plan that adds a persistent identifier (id). Plan itself (external, dcat-ap-plus) only lists title/description -- every CoreMeta4Cat protocol, technique, and method class needs to be independently citable and cross-referenceable (e.g. linked to from multiple Reaction/Characterization instances that reuse the same protocol), so id is added once here rather than repeated on each of PreparationMethod, CharacterizationTechnique, SimulationMethod, and ProductIdentificationMethod individually. |
no |
| IUPACName | A systematic name which is formulated according to the rules and recommendations for chemical nomenclature set out by the International Union of Pure and Applied Chemistry (IUPAC). | no |

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. |

| ReactionMonitoring | A DataGeneratingActivity that produces data about a ChemicalReaction, such as reaction monitoring, experimental documentation, or a combined recording-and-evaluation workflow. This is a coarse-grained convenience shape that does not distinguish between raw experimental recording and subsequent data evaluation.

In practice, users should reference a concrete CharacterizationTechnique subclass from coremeta4cat_characterization_ap (e.g. GCMS, HPLC_MS, NMRSpectroscopy). This abstract class is retained for backward compatibility with the original CoreMeta4Cat monolith. It is a subclass of CatalysisPlan (which is itself a Plan, prov:Plan / OBI:0000272) so that it can participate in the realized_plan slot, and so it (and every other CoreMeta4Cat protocol/technique class) can carry a persistent id. |
