Applicable Classes

Name	Description	Modifies Slot
Policy	See DCAT-AP specs:Policy	no
EnergyQuantity	A quantitative measure of energy (eV, keV, kJ/mol, etc.).	no
PeriodOfTime	See DCAT-AP specs:PeriodOfTime	no
PhononDispersion	Phonon dispersion relations computed from interatomic force constants, providing access to vibrational frequencies, thermodynamic quantities, and dynamical stability (imaginary modes).	no
Volume	A measure of regions in three-dimensional space.	no
SamplePretreatment	A qualitative descriptor of the pre-treatment applied to a sample before a process or measurement (e.g. "reduction at 300 °C", "outgassing").	no
PlugFlowReactor	Plug flow reactor (PFR) — a tubular reactor in which reactant composition varies along the axis with no axial mixing.	no
InfraredSpectroscopy	Infrared spectroscopy (FTIR/ATR) for functional group and surface species identification.	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
DRIFTS	Diffuse reflectance infrared Fourier transform spectroscopy for in-situ surface species identification under reactive gas conditions.	no
Geometry	See DCAT-AP specs:Geometry	no
ProvenanceStatement	See DCAT-AP specs:ProvenanceStatement	no
EvaluatedEntity	An Entity that is being evaluated in a DataGeneratingActivity.	yes
Entity	A physical, digital, conceptual, or other kind of thing with some fixed aspects; entities may be real or imaginary.	yes

Software	An instrument composed of a series of instructions that can be interpreted by or directly executed by a computer.	no
Activity	See DCAT-AP specs:Activity	yes
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.	no
QualitativeAttribute	A piece of information that is attributed to an Entity, Activity or AgenticEntity.	no

Identifier	See DCAT-AP specs:Identifier	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.	no
TimeInstant	See DCAT-AP specs:TimeInstant	no

Surrounding	The surrounding in which the dataset creating activity took place (e.g. a lab).	no
ProductIdentificationMethod	Abstract Plan representing the method used to identify and quantify reaction products. 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.	no

Provide the shared unit as a QUDT DefinedTerm.	no
ReactionMonitoringDataset	A Dataset about a ChemicalReaction that was produced by a ReactionMonitoring activity. This is a coarse-grained convenience shape that conflates experimental documentation and analysis into a single data-generating activity. Domain-specific sub-profiles that need to distinguish reaction monitoring from subsequent data evaluation should define their own Dataset subclasses, potentially using the DCAT-AP+ DataAnalysis/AnalysisDataset chain instead of reusing this class.	no
Role	See DCAT-AP specs:Role	no
ChemicalReactor	Abstract Reactor (chemdcat-ap) subclass representing a catalytic reactor vessel. Reactor is more specific than the general Device (AgenticEntity): it restricts the used_reactor relation (is_a: carried_out_by) on Reaction to dedicated reactor equipment. This semantic distinction separates analytical instruments (Device) from reaction vessels (Reactor). ChemicalReactor further specializes chemdcat-ap's generic Reactor for catalysis use cases. Concrete subclasses (FixedBedReactor, CSTR, PlugFlowReactor, …) specify reactor geometry and operating mode. Linked from Reaction via used_reactor (restricted to range: ChemicalReactor).	no
