Applicable Classes

Name	Description	Modifies Slot
QuantitativeAttribute	A quantifiable piece of information that is attributed to an Entity, Activity or AgenticEntity.	no
DissolvingSubstance	A liquid ChemicalSubstance that dissolves or that is capable of dissolving a ChemicalSubstance.	no
EvaluatedEntity	An Entity that is being evaluated in a DataGeneratingActivity.	no
MaterialSample	A Sample that was derived from a previous MaterialSample or some other kind of MaterialEntity.	no
DataGeneratingActivity	An Activity (process) that has the objective to produce information (in form of a dataset) about another Activity or Entity.	no
AnalysisSourceData	Information that was evaluated within a DataAnalysis.	no
QualitativeAttribute	A piece of information that is attributed to an Entity, Activity or AgenticEntity.	no
Temperature	A physical quantity that quantitatively expresses the attribute of hotness or coldness.	no
MaterialEntity	A material is an Entity that has some portion of matter as proper part.	no
AmountOfSubstance	The total amount of substance used in a ChemicalReaction.	no
Surrounding	The surrounding in which the dataset creating activity took place (e.g. a lab).	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
Laboratory	A facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed.	no
Pressure		no
Activity	See DCAT-AP specs:Activity	no
DataAnalysis	An Activity that evaluates the data produced by another Activity.	no
MolarEquivalent	A dimensionless ratio that quantifies the stoichiometric proportion of a chemical substance relative to a reference substance in a chemical reaction.	no
ClassifierMixin	A mixin with which an entity of this schema can be classified via an additional rdf:type or dcterms:type assertion.	no
EvaluatedActivity	An activity or process that is being evaluated in a DataGeneratingActivity.	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
SMILES	A structure descriptor that denotes a molecular structure as a graph and conforms to the SMILES format specification.	no
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
Concentration	A QuantitativeAttribute of a ChemicalSubstance that represents the amount of a constituent divided by the volume of the mixture.	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
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
Volume	A measure of regions in three-dimensional space.	no
SubstanceSample	A MaterialSample derived from a chemical substance that is of interest in an analytical procedure.	no
InChi	A structure descriptor which conforms to the InChI format specification.	no
Catalyst	A ChemicalSubstance or MaterialEntity that initiates or accelerates a ChemicalReaction without itself being affected.	no
AgenticEntity	An entity that is somehow responsible for an Activity to take place.	no
PolymerSample	A SubstanceSample derived from a Polymer.	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
StartingMaterial	A ChemicalSubstance with that has a starting material role in a synthesis.	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
Entity	A physical, digital, conceptual, or other kind of thing with some fixed aspects; entities may be real or imaginary.	no
PHValue		no
Mass	The strength of a body's gravitational attraction to other bodies.	no
PercentageOfTotal	A dimensionless ratio that quantifies the stoichiometric proportion of a chemical substance relative to a reference substance in a chemical reaction.	no
Atom	An Entity constituting the smallest component of a chemical element having the chemical properties of the element.	yes
InChIKey		no
Density	A measure of the mass per unit volume of a substance.	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
ChemicalProduct	A chemical substance that is produced by a ChemicalReaction.	no
Device	A material instrument that is designed to perform a function primarily by means of its mechanical or electrical nature.	no
MolarMass	A Mass (physical quality) that quantifies the mass of a homogeneous ChemicalSubstance containing 6.02 x 10^23 atoms or molecules.	no
Reactor	A reactor is a container for controlling a biological or chemical reaction or process.	no
Software	An instrument composed of a series of instructions that can be interpreted by or directly executed by a computer.	no
