Class Property
2 typesschema.org
An additional type for the item, typically used for adding more specific types from external vocabularies in microdata syntax. This is a relationship between something and a class that the thing is in. Typically the value is a URI-identified RDF class, and in this case corresponds to the use of rdf:type in RDF. Text values can be used sparingly, for cases where useful information can be added without their being an appropriate schema to reference. In the case of text values, the class label should follow the schema.org [style guide](https://schema.org/docs/styleguide.html).
Class Property
1 typeschema.org
The number of completed interactions for this entity, in a particular role (the 'agent'), in a particular action (indicated in the statistic), and in a particular context (i.e. interactionService).
Class Property

A sub property of description. A short description of the item used to disambiguate from other, similar items. Information from other properties (in particular, name) may be necessary for the description to be useful for disambiguation.
Class Property
2 typesschema.org
Gender of something, typically a [Person](https://schema.org/Person), but possibly also fictional characters, animals, etc. While https://schema.org/Male and https://schema.org/Female may be used, text strings are also acceptable for people who are not a binary gender. The [gender](https://schema.org/gender) property can also be used in an extended sense to cover e.g. the gender of sports teams. As with the gender of individuals, we do not try to enumerate all possibilities. A mixed-gender [SportsTeam](https://schema.org/SportsTeam) can be indicated with a text value of "Mixed".
Class Property

The [Global Location Number](http://www.gs1.org/gln) (GLN, sometimes also referred to as International Location Number or ILN) of the respective organization, person, or place. The GLN is a 13-digit number used to identify parties and physical locations.

The identifier property represents any kind of identifier for any kind of [Thing](https://schema.org/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](https://schema.org/docs/datamodel.html#identifierBg) for more details.
Class Property

Of a [Person](https://schema.org/Person), and less typically of an [Organization](https://schema.org/Organization), to indicate a topic that is known about - suggesting possible expertise but not implying it. We do not distinguish skill levels here, or relate this to educational content, events, objectives or [JobPosting](https://schema.org/JobPosting) descriptions.
Class Property
2 typesschema.org
Of a [Person](https://schema.org/Person), and less typically of an [Organization](https://schema.org/Organization), to indicate a known language.

Class Property
3 typesschema.org
A short string listing or describing pronouns for a person. Typically the person concerned is the best authority as pronouns are a critical part of personal identity and expression. Publishers and consumers of this information are reminded to treat this data responsibly, take country-specific laws related to gender expression into account, and be wary of out-of-date data and drawing unwarranted inferences about the person being described. In English, formulations such as "they/them", "she/her", and "he/him" are commonly used online and can also be used here. We do not intend to enumerate all possible micro-syntaxes in all languages. More structured and well-defined external values for pronouns can be referenced using the [StructuredValue](https://schema.org/StructuredValue) or [DefinedTerm](https://schema.org/DefinedTerm) values.
Class Property

The publishingPrinciples property indicates (typically via [URL](https://schema.org/URL)) a document describing the editorial principles of an [Organization](https://schema.org/Organization) (or individual, e.g. a [Person](https://schema.org/Person) writing a blog) that relate to their activities as a publisher, e.g. ethics or diversity policies. When applied to a [CreativeWork](https://schema.org/CreativeWork) (e.g. [NewsArticle](https://schema.org/NewsArticle)) the principles are those of the party primarily responsible for the creation of the [CreativeWork](https://schema.org/CreativeWork). While such policies are most typically expressed in natural language, sometimes related information (e.g. indicating a [funder](https://schema.org/funder)) can be expressed using schema.org terminology.
