Materialhub is a digital object repository for materials science data that combines the power of ontologies and databases. It employs an expanded subset of the schema.org vocabulary to describe materials and topics necessary for databases such as authors, dates, citations, etc. The NIST material-schema is used to supplement schema.org for more materials science specific terminology.

Real or simulated matter with prescribed and actual composition, structure, properties, and performance. Created by a Process.
The ability of a material to perform in a given application. Includes the materials response to a complex environment usually as a component or in some other end use application.
The physical properties of a material. Includes first-principles type properties and those determined through precise testing.
The structure of a material constitutes the many physical and chemical components of the material and their spatial inter-relationships.
A change in a material due to an environment controlled by natural processes (e.g., solidification, precipitation, grain coarsening, corrosion, etc.), instruments (e.g., furnace, etc.), or simulations (e.g., phase field, etc.).
The actual process as determined by measurements.
The intended or prescribed process.
An action performed by a direct agent and indirect participants upon a direct object. Optionally happens at a location with the help of an inanimate instrument. The execution of the action may produce a result. Specific action sub-type documentation specifies the exact expectation of each argument/role.

The endTime of something. For a reserved event or service (e.g. FoodEstablishmentReservation), the time that it is expected to end. For actions that span a period of time, when the action was performed. e.g. John wrote a book from January to December. For media, including audio and video, it's the time offset of the end of a clip within a larger file.
Note that Event uses startDate/endDate instead of startTime/endTime, even when describing dates with times. This situation may be clarified in future revisions.

Indicates an item or CreativeWork that is part of this item, or CreativeWork (in some sense).
The identifier property represents any kind of identifier for any kind of [[Thing]], such as ISBNs, GTIN codes, UUIDs etc. Schema.org provides dedicated properties for representing many of these, either as textual strings or as URL (URI) links. See background notes for more details.

A [[DefinedTermSet]] that contains this term.
The object that helped the agent perform the action. e.g. John wrote a book with a pen.

The upper value of some characteristic or property.
A technique or technology used in a [[Dataset]] (or [[DataDownload]], [[DataCatalog]]), corresponding to the method used for measuring the corresponding variable(s) (described using [[variableMeasured]]). This is oriented towards scientific and scholarly dataset publication but may have broader applicability; it is not intended as a full representation of measurement, but rather as a high level summary for dataset discovery. For example, if [[variableMeasured]] is: molecule concentration, [[measurementTechnique]] could be: 'mass spectrometry' or 'nmr spectroscopy' or 'colorimetry' or 'immunofluorescence'. If the [[variableMeasured]] is 'depression rating', the [[measurementTechnique]] could be 'Zung Scale' or 'HAM-D' or 'Beck Depression Inventory'. If there are several [[variableMeasured]] properties recorded for some given data object, use a [[PropertyValue]] for each [[variableMeasured]] and attach the corresponding [[measurementTechnique]].
The lower value of some characteristic or property.
