[goodrelations] Joining gr:hasEAN_UCC-13, gr:hasGTIN-8, gr:hasGTIN-14 ?

Hello everybody,

Is it possible to join into one parameter [ ex. hasGTIN, with same
cardinality (0..*) ] all 3 existing Datatype Properties gr:hasEAN_UCC-13,
gr:hasGTIN-8, gr:hasGTIN-14 ?


The aspect is considered by GoodRelations public draft for alignment with
Schema.org [ at column 5 ]

Schema.org has already designated <meta itemprop='productID'

<div itemscope itemtype="http://schema.org/Property"
   <link itemprop="domain" href="http://schema.org/Product"/>
   <link itemprop="range" href="http://schema.org/Text"/>

Reasoning from practical perspective:

1. Many ERP's have one field only for product barcode EAN_UCC, while
allowing simultaneous use of multiple  barcodes for same product [ one to
many relationship for barcode field inside ERP ]. Field allows input of
barcode EAN / UCC 8, 12, 13.

2. Product barcode alternates randomly from EAN_UCC-8 to EAN-UCC-13 for
same SKU.

Situation is frequent for multinational consumer goods with same brand and
SKU orifginating from different manufacturing sites arount the globe and
destinated to different markets.

Best regards,

Radu Silaghi
