PropertyExpected TypeDescription Properties from OrderAction deliveryMethod DeliveryMethod A sub property of instrument. The method of delivery. Properties from TradeAction price Number  or
Text The offer price of a product, or of a price component when attached to PriceSpecification and its subtypes.

Usage guidelines:

• Use the priceCurrency property (with standard formats: ISO 4217 currency format, e.g. "USD"; Ticker symbol for cryptocurrencies, e.g. "BTC"; well known names for Local Exchange Trading Systems (LETS) and other currency types, e.g. "Ithaca HOUR") instead of including ambiguous symbols such as '$' in the value.
• Use '.' (Unicode 'FULL STOP' (U+002E)) rather than ',' to indicate a decimal point. Avoid using these symbols as a readability separator.
• Note that both RDFa and Microdata syntax allow the use of a "content=" attribute for publishing simple machine-readable values alongside more human-friendly formatting.
• Use values from 0123456789 (Unicode 'DIGIT ZERO' (U+0030) to 'DIGIT NINE' (U+0039)) rather than superficially similar Unicode symbols.

priceCurrency Text The currency of the price, or a price component when attached to PriceSpecification and its subtypes.

Use standard formats: ISO 4217 currency format, e.g. "USD"; Ticker symbol for cryptocurrencies, e.g. "BTC"; well known names for Local Exchange Trading Systems (LETS) and other currency types, e.g. "Ithaca HOUR".

target EntryPoint  or
URL Indicates a target EntryPoint, or url, for an Action. Properties from Thing additionalType Text  or
URL 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. alternateName Text An alias for the item. description Text  or
TextObject A description of the item. disambiguatingDescription Text 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. identifier PropertyValue  or
