Applicable Classes

Name	Description	Modifies Slot
Yield	A dimensionless physical quantity describing the fraction of a product B that is formed from a reactant A taking into account the stoichiometry. If A fully reacts to B without side-reactions, the yield of product B is 1 (or 100 %).	no
SubstanceSampleCharacterization	A DataGeneratingActivity that produces data about a SubstanceSample, such as a spectroscopic measurement, a physical property determination, or a combined measurement-and-analysis workflow. This is a coarse-grained convenience shape that does not distinguish between raw data acquisition and subsequent data processing or analysis. Domain-specific sub-profiles that need this distinction should define their own DataGeneratingActivity subclasses and use the DCAT-AP+ DataAnalysis chain to separate raw measurement from derived results.	no
Reactor	A reactor is a container for controlling a biological or chemical reaction or process.	no
AnalysisSourceData	Information that was evaluated within a DataAnalysis.	no
DataAnalysis	An Activity that evaluates the data produced by another Activity.	no
AgenticEntity	An entity that is somehow responsible for an Activity to take place.	no
Software	An instrument composed of a series of instructions that can be interpreted by or directly executed by a computer.	no
StartingMaterial	A ChemicalSubstance with that has a starting material role in a synthesis.	no
SMILES	A structure descriptor that denotes a molecular structure as a graph and conforms to the SMILES format specification.	no
Density	A measure of the mass per unit volume of a substance.	no
EvaluatedActivity	An activity or process that is being evaluated in a DataGeneratingActivity.	no
Activity	See DCAT-AP specs:Activity	no
PHValue		no
Temperature	A physical quantity that quantitatively expresses the attribute of hotness or coldness.	no
Laboratory	A facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed.	no
DissolvingSubstance	A liquid ChemicalSubstance that dissolves or that is capable of dissolving a ChemicalSubstance.	no
Concentration	A QuantitativeAttribute of a ChemicalSubstance that represents the amount of a constituent divided by the volume of the mixture.	no
Entity	A physical, digital, conceptual, or other kind of thing with some fixed aspects; entities may be real or imaginary.	no
DataGeneratingActivity	An Activity (process) that has the objective to produce information (in form of a dataset) about another Activity or Entity.	no
ChemicalReaction	A process that leads to the transformation of one set of chemical substances to another and that is the subject matter of a DataGeneratingActivity.	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
ChemicalEntity	Any constitutionally or isotopically distinct atom, molecule, ion, ion pair, radical, radical ion, complex, conformer etc., identifiable as a separately distinguishable entity.	no
MaterialEntity	A material is an Entity that has some portion of matter as proper part.	no
Volume	A measure of regions in three-dimensional space.	no
Mass	The strength of a body's gravitational attraction to other bodies.	no
Device	A material instrument that is designed to perform a function primarily by means of its mechanical or electrical nature.	no
SubstanceSample	A MaterialSample derived from a chemical substance that is of interest in an analytical procedure.	no
EvaluatedEntity	An Entity that is being evaluated in a DataGeneratingActivity.	no
MolarEquivalent	A dimensionless ratio that quantifies the stoichiometric proportion of a chemical substance relative to a reference substance in a chemical reaction.	no
PolymerSample	A SubstanceSample derived from a Polymer.	no
ChemicalProduct	A chemical substance that is produced by a ChemicalReaction.	no
Surrounding	The surrounding in which the dataset creating activity took place (e.g. a lab).	no
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. Domain-specific sub-profiles that need this distinction should define their own DataGeneratingActivity subclasses and use the DCAT-AP+ DataAnalysis chain to separate raw data from derived results.	no
AmountOfSubstance	The total amount of substance used in a ChemicalReaction.	no
PercentageOfTotal	A dimensionless ratio that quantifies the stoichiometric proportion of a chemical substance relative to a reference substance in a chemical reaction.	no
Catalyst	A ChemicalSubstance or MaterialEntity that initiates or accelerates a ChemicalReaction without itself being affected.	no
Atom	An Entity constituting the smallest component of a chemical element having the chemical properties of the element.	yes
InChi	A structure descriptor which conforms to the InChI format specification.	no
Pressure		no
MaterialSample	A Sample that was derived from a previous MaterialSample or some other kind of MaterialEntity.	no
ClassifierMixin	A mixin with which an entity of this schema can be classified via an additional rdf:type or dcterms:type assertion.	no
Plan	A piece of information that specifies how an activity has to be carried out by its agents including what kind of steps have to be taken and what kind of parameters have to be met/set.	no
InChIKey		no
MolecularFormula	A structure descriptor which identifies each constituent element by its chemical symbol and indicates the number of atoms of each element found in each discrete molecule of that compound.	no
Reagent	A ChemicalSubstance that is consumed or transformed in a ChemicalReaction.	no
QuantitativeAttribute	A quantifiable piece of information that is attributed to an Entity, Activity or AgenticEntity.	no
QualitativeAttribute	A piece of information that is attributed to an Entity, Activity or AgenticEntity.	no
MolarMass	A Mass (physical quality) that quantifies the mass of a homogeneous ChemicalSubstance containing 6.02 x 10^23 atoms or molecules.	no
