• ObjectProperty

• Class

add-on (0..*)

This property points from a gr:Offering to additional offerings that can only be obtained in combination with the first offering. This can be used to model supplements and extensions that are available for a surcharge. Any gr:PriceSpecification attached to the secondary offering is to be understood as an additional charge.

• ObjectProperty

advance booking requirement (0..1)

The minimal and maximal amount of time that is required between accepting the gr:Offering and the actual usage of the resource or service. This is mostly relevant for offers regarding hotel rooms, the rental of objects, or the provisioning of services. The duration is specified relatively to the beginning of the usage of the contracted object. It is represented by attaching an instance of the class gr:QuantitativeValueInteger. The lower and upper boundaries are specified using the properties gr:hasMinValueInteger and gr:hasMaxValueInteger to that instance. The unit of measurement is specified using the property gr:hasUnitOfMeasurement with a string holding a UN/CEFACT code suitable for durations, e.g. MON (months), DAY (days), HUR (hours), or MIN (minutes). The difference to the gr:validFrom and gr:validThrough properties is that those specify the interval during which the gr:Offering is valid, while gr:advanceBookingRequirement specifies the acceptable relative amount of time between accepting the offer and the fulfilment or usage.

This property specifies the end of the availability of the gr:ProductOrService included in the gr:Offering.

Example: I offer to lease my boat for the period of August 1 - August 31, 2010, but you must accept by offer no later than July 15. A time-zone should be specified. For a time in GMT/UTC, simply add a "Z" following the time: 2008-05-30T09:30:10Z. Alternatively, you can specify an offset from the UTC time by adding a positive or negative time following the time: 2008-05-30T09:30:10-09:00 or 2008-05-30T09:30:10+09:00. Note: There is another property gr:availableAtOrFrom, which is used to indicate the gr:Location (e.g. store or shop) from which the goods would be available.

• DatatypeProperty

This property specifies the beginning of the availability of the gr:ProductOrService included in the gr:Offering. The difference to the properties gr:validFrom and gr:validThrough is that those specify the period of time during which the offer is valid and can be accepted. Example: I offer to lease my boat for the period of August 1 - August 31, 2010, but you must accept by offer no later than July 15. A time-zone should be specified.

• ObjectProperty

billing increment (0..1)

This property specifies the minimal quantity and rounding increment that will be the basis for the billing. The unit of measurement is specified by the UN/CEFACT code attached to the gr:UnitPriceSpecification via the gr:hasUnitOfMeasurement property. Examples: - The price for gasoline is 4 USD per gallon at the pump, but you will be charged in units of 0.1 gallons. - The price for legal consulting is 100 USD per hour, but you will be charged in units of 15 minutes.

Business (business entity type)

The gr:BusinessEntityType representing such agents that are themselves offering commercial services or products on the market. Usually, businesses are characterized by the fact that they are officially registered with the public administration and strive for profits by their activities.

Business entity

An instance of this class represents the legal agent making (or seeking) a particular offering. This can be a legal body or a person. A business entity has at least a primary mailing address and contact details. For this, typical address standards (vCard) and location data (geo, WGS84) can be attached. Note that the location of the business entity is not necessarily the location from which the product or service is being available (e.g. the branch or store). Use gr:Location for stores and branches. Example: Siemens Austria AG, Volkswagen Ltd., Peter Miller's Cell phone Shop LLC Compatibility with schema.org: This class is equivalent to the union of http://schema.org/Person and http://schema.org/Organization.

• Class

Business entity type

A business entity type is a conceptual entity representing the legal form, the size, the main line of business, the position in the value chain, or any combination thereof, of a gr:BusinessEntity. From the ontological point of view, business entity types are mostly roles that a business entity has in the market. Business entity types are important for specifying eligible customers, since a gr:Offering is often valid only for business entities of a certain size, legal structure, or role in the value chain. Examples: Consumers, Retailers, Wholesalers, or Public Institutions

• Class

The business function specifies the type of activity or access (i.e., the bundle of rights) offered by the gr:BusinessEntity on the gr:ProductOrService through the gr:Offering.

Licenses and other proprietary specifications of access rights are also instances of this class.
