Operation: GetClassificationScheme
- Michelle Zaczek (Unlicensed)
It is common practice to assign items to product groups in order to structure the assortment. Some vendors grant quantity discounts in a form necessitating a grouping of items to determine the discount. Assignment to groups can be understood generically as a classification of items according to a scheme. The GetClassificationScheme operation can be used to communicate employed classification schemes.
The GetClassificationScheme operation consists of a vcc:GetClassificationSchemeRequest of vct:RequestType. The server responds to it with vcc:GetClassificationSchemeResponse of vct:ResponseType, extended by a non-empty sequence of vcc: ClassificationScheme elements.
 The element vcc:ClassificationScheme has the singleMapping attribute which is set to true by default, and consists of the element vcc:ClassificationSchemeID of type udt:IdentifierType, followed by vcc:ClassificationSchemeURI of type xsd:anyURI or a non-empty list of elements vcc:ClassificationSchemeGroup.
The element vcc:ClassificationSchemeGroup comprises the following elements:
Name | Type/occurrence | Description |
|---|---|---|
vcc:ID | udt:IdentifierType | Unique identification of the group within a scheme. |
vcc:ParentID | udt:IdentifierType? | Reference to parent group in hierarchical group structure. |
vcc:Description | cct:TextType | Group description. |
Note: It is possible to classify the assortment in different ways and for different purposes. Classification into product groups is only one possible use case for the generic classification mechanism.
Rule: ClassificationScheme
A Veloconnect-compliant server must communicate all employed classification schemes via the GetClassificationScheme operation. References to a specific group of a classification scheme consist of the IDs of the scheme and the group.
If the singleMapping attribute of a classification scheme has the value true, at most one group of this scheme must be associable to each item.
Classification schemes must be distinguishable in terms of those which are either proprietary and only valid for particular suppliers, or those which are standardized, i.e. public and supplier-independent. In the case of a proprietary scheme, the server communicates the related groups via vcc:ClassificationSchemeGroup elements. In the case of a standardized scheme, the group structure is communicated via a URL which makes it possible to obtain the necessary information about the groups of this scheme.
Because the bicycle sector presently appears to lack practical, commonly employed, standard classification schemes, a use of such schemes with Veloconnect applications will remain just hypothetical until further notice.
Rule: BIDEX
There is now a sector-specific product group key: BIDEX
This product group key is used as follows:
The text BIDEX is used as the ClassificationSchemeID.
Used for this ClassificationSchemeID in ClassificationSchemeResponse instead of the ClassificationSchemeGroupMember elements is the ClassificationSchemeURI element with the content http://veloconnect.bidex.bike/GetClassificationScheme. This URL supplies the groups of the BIDEX product key as ClassificationSchemeResponse.
As part of other languages, the appropriate ClassificationSchemeURI from the following list is used.
