Different attibutes to a products under one category ?

I've requirement where attributes for Products are not constant. There are different line of businesses (LOB), in each LOB - products may have different attributes. There might arise a case , where - products under one category may have different attributes. I'm considering Classification system for this - but i'm not sure whether we can apply classification system on each individual product if case arise. Is this the correct approach - Also i've to implement solr for this products. How complex can this become.

If i cant go with Classification system how can i achieve this requirement , where product attributes are different for different categories/products and might be added based on different LOB's.

Please advise ?

Thanks, Sandeep

    Indeed classification is the right approach, it fulfills all your requirements, it can be applied to a single product and you can use "Valuelist" (enumtype) to have the attribute with an array of possible values. Solr will work with classification attributes.

    Useful links:
    Classification system :

    Configure SOLR:
    Depending on how the business wants products indexed there are two options for indexing classification attributes: CommerceClassifcationPropertyValueProvider - Indexes an attribute associated to the classification class. See electronics solr for an example - Mega Pixel is faceted against class picture quality ClassificationPropertyValueProvider - creates a facet on the attribute regardless of the class if belongs too.

    See the example below

    New facet search based on classification attribute
    In order to define Solr facet search based on classificaiton attribute you could customize below snippet to your needs.

    CLASSIFICATION_ATTRIBUTE_CODE links to classification attribute
    SOLR_INDEXED_PROPERTY_TYPE defines type of data which is indexed, can have one of possible values:
    FACET_TYPE defines how we will filter results based on the facet selection
    Refine - exactly one selection
    MultiSelectOr - sums results
    MultiSelectAnd - make sense only for multivalued fields, filters results that contains all selections
    FACET_SORT defines how values will be sorted
    Alpha - alphanumerically
    Custom - possibility to link sort to spring bean that will calculate value used to order
    PRIORITY defines order in which facet appears, bigger the number, higher facet appears (to have facet visible value must be bigger than 0)
    SOLR_RANGE links to ranges definition that will be used to group common results
    CLASSIFICATION_CLASS_CODE:::CLASSIFICATION_ATTRIBUTE_CODE:::: - exactly in this format defines link between solr property and classification attribute value

    # Define macros needed to select proper classification system

    INSERT_UPDATE SolrIndexedProperty;solrIndexedType(identifier)
    [unique=true];name[unique=true];type(code);sortableType(code);currency[default=false];localized[default=false];multiValue[default=false];facet[default=false];facetType(code);facetSort(code);priority;fieldValueProvider;customFacetSortProvider;rangeSets(name);$classAttributeAssignment #;$solrIndexedType;CLASSIFICATION_ATTRIBUTE_CODE;SOLR_INDEXED_PROPERTY_TYPE;;;;;true;FACET_TYPE;FACET_SORT;PRIORITY;commerceClassificationPropertyValueProvider;;SOLR_RANGE;CLASSIFICATION_CLASS_CODE:::CLASSIFICATION_ATTRIBUTE_CODE::::

      Thanks Zardini, So can you tell me which is the better approach among these - going with our design (where all product attributes and values are defined in impex as a collection and assigning it to product) or classification system. 1) How can we implement solr if we go with the design which i've shared, as the attributes are not predefined , how to index these dynamic attributes. 2) can i leverage OOTB code if go with my generic design or will i face any problems in future implementations.

      Please advise.

      Thanks, Sandeep

    Do you have reasons why you don't want to use classification?
