The materialhub ontology

The conditions observed while studying a process, studying a material, or taking some type of measurement.

A parameter that can be controlled by an instrument, simulation parameter, or other means.

A process history that has occured and which this object describes.

A control process or process protocol to which this object is related to.

The material supply for a process.

uncertainty in some measured property

The subject matter of the content.

Specifies the Person that is legally accountable for the CreativeWork.

Physical address of the item.

An organization that this person is affiliated with. For example, a school/university, a club, or a team.

The direct performer or driver of the action (animate or inanimate). e.g. John wrote a book.

An alias for the item.

The author of this content or rating. Please note that author is special in that HTML 5 provides a special mechanism for indicating authorship via the rel tag. That is equivalent to this and may be used interchangeably.

The brand(s) associated with a product or service, or the brand(s) maintained by an organization or business person.

A citation or reference to another creative work, such as another publication, web page, scholarly article, etc.

Comments, typically from users.

A secondary contributor to the CreativeWork or Event.

The party holding the legal copyright to the CreativeWork.

The creator/author of this CreativeWork. This is the same as the Author property for CreativeWork.

The date on which the CreativeWork was created or the item was added to a DataFeed.

The date on which the CreativeWork was most recently modified or when the item's entry was modified within a DataFeed.

Date of first broadcast/publication.

A description of the item.

Specifies the Person who edited the CreativeWork.

Email address.

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.

A creative work that this work is an example/instance/realization/derivation of.

Family name. In the U.S., the last name of a Person.

A person or organization that supports (sponsors) something through some kind of financial contribution.

Given name. In the U.S., the first name of a Person.

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.

An image of the item. This can be a [[URL]] or a fully described [[ImageObject]].

A [[DefinedTermSet]] that contains this term.

The object that helped the agent perform the action. e.g. John wrote a book with a pen.

Indicates an item or CreativeWork that this item, or CreativeWork (in some sense), is part of.

Keywords or tags used to describe this content. Multiple entries in a keywords list are typically delimited by commas.

A license document that applies to this content, typically indicated by URL.

The location of, for example, where an event is happening, where an organization is located, or where an action takes place.

The manufacturer of the product.

A material that something is made from, e.g. leather, wool, cotton, paper.

The quantity of the materials being described or an expression of the physical space they occupy.

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.

The model of the product. Use with the URL of a ProductModel or a textual representation of the model identifier. The URL of the ProductModel can be from an external source. It is recommended to additionally provide strong product identifiers via the gtin8/gtin13/gtin14 and mpn properties.

The name of the item.

The object upon which the action is carried out, whose state is kept intact or changed. Also known as the semantic roles patient, affected or undergoer (which change their state) or theme (which doesn't). e.g. John read a book.

Operating systems supported (Windows 7, OSX 10.6, Android 1.6, etc.).

Other co-agents that participated in the action indirectly. e.g. John wrote a book with Steve.

The product identifier, such as ISBN. For example: meta itemprop='productID' content='isbn:123-456-789'.

The date of production of the item, e.g. vehicle.

The computer programming language.

The service provider, service operator, or service performer; the goods producer. Another party (a seller) may offer those services or goods on behalf of the provider. A provider may also serve as the seller.

The publisher of the creative work.

The date the item e.g. vehicle was purchased by the current owner.

The result produced in the action. e.g. John wrote a book.

The serial number or any alphanumeric identifier of a particular product. When attached to an offer, it is a shortcut for the serial number of the product included in the offer.

Component dependency requirements for application. This includes runtime environments and shared libraries that are not included in the application distribution package, but required to run the application (Examples: DirectX, Java or .NET runtime).

Version of the software instance.

The 'spatial' property can be used in cases when more specific properties (e.g. [[locationCreated]], [[spatialCoverage]], [[contentLocation]]) are not known to be appropriate.

The startTime of something. For a reserved event or service (e.g. FoodEstablishmentReservation), the time that it is expected to start. 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 start 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.

A CreativeWork or Event about this Thing.

Indicates a target EntryPoint for an Action.

Target Operating System / Product to which the code applies. If applies to several versions, just the product name can be used.

The telephone number.

A code that identifies this [[DefinedTerm]] within a [[DefinedTermSet]]

A thumbnail image relevant to the Thing.

The unit of measurement given using the UN/CEFACT Common Code (3 characters) or a URL. Other codes than the UN/CEFACT Common Code may be used with a prefix followed by a colon.

A string or text indicating the unit of measurement. Useful if you cannot provide a standard unit code for unitCode.

URL of the item.

The value of the quantitative value or property value node.

• For [[QuantitativeValue]] and [[MonetaryAmount]], the recommended type for values is 'Number'.
• For [[PropertyValue]], it can be 'Text;', 'Number', 'Boolean', or 'StructuredValue'.
• Use values from 0123456789 (Unicode 'DIGIT ZERO' (U+0030) to 'DIGIT NINE' (U+0039)) rather than superficially similiar Unicode symbols.
• Use '.' (Unicode 'FULL STOP' (U+002E)) rather than ',' to indicate a decimal point. Avoid using these symbols as a readability separator.

A secondary value that provides additional information on the original value, e.g. a reference temperature or a type of measurement.

The variableMeasured property can indicate (repeated as necessary) the variables that are measured in some dataset, either described as text or as pairs of identifier and description using PropertyValue.
