`id`	identifier for the object (URI)
`serviceUrl`	(URL type.) The website to access the service.
`serviceSmsNumber`	(ContactPoint type.) The number to access the service by text message.
`servicePostalAddress`	(PostalAddress type.) The address for accessing the service by mail.
`servicePhone`	(ContactPoint type.) The phone number to use to access the service.
`serviceLocation`	(Place type.) The location (e.g. civic structure, local business, etc.) where a person can go to access the service.
`providesService`	(Service type.) The service provided by this channel.
`processingTime`	(Duration type.) Estimated processing time for the service using this channel.
`availableLanguage`	(Text or Language or Text or Language or Text or Language or Text or Language type.) A language someone may use with or at the item, service or place. Please use one of the language codes from the [IETF BCP 47 standard](http://tools.ietf.org/html/bcp47). See also [[inLanguage]]
`url`	(URL type.) URL of the item.
`sameAs`	(URL type.) URL of a reference Web page that unambiguously indicates the item's identity. E.g. the URL of the item's Wikipedia page, Wikidata entry, or official website.
`potentialAction`	(Action type.) Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role.
`name`	(Text type.) The name of the item.
`mainEntityOfPage`	(URL or CreativeWork type.) Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See [background notes](/docs/datamodel.html#mainEntityBackground) for details.
`image`	(URL or ImageObject type.) An image of the item. This can be a [[URL]] or a fully described [[ImageObject]].
`identifier`	(URL or Text or PropertyValue type.) 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](/docs/datamodel.html#identifierBg) for more details.
`disambiguatingDescription`	(Text type.) 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.
`description`	(Text type.) A description of the item.
`alternateName`	(Text type.) An alias for the item.
`additionalType`	(URL type.) 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. In RDFa syntax, it is better to use the native RDFa syntax - the 'typeof' attribute - for multiple types. Schema.org tools may have only weaker understanding of extra types, in particular those defined externally.
