Support ISO/IEC 6523 as identifier for /Organization

[alex-jansen]

The /Organization type has several identification properties, for example, /duns, /leiCode, /globalLocationNumber, /vatID and /taxID.

Many of these existing identifiers can be expressed using the ISO/IEC 6523 standard. ISO 6523 codes are composed from an International Code Designator (ICD) value, which identifies the type of the code (e.g., 0060 for DUNS, 0199 for leiCode, or 9910+9920-9957 for European /vatID), and an Organization Identifier (OI) which identifies the organization within that frame of reference.

We therefore propose to add a new property /iso6523 with values of type /Text for use on type /Organization. Alternatively we could introduce a structured type with the 2 fields ICD and OI for values of /iso6523, but since /leiCode allows values of type /Text we propose to do the same for /iso6523 for consistency.

This issue is being nudged due to inactivity.

ISO/IEC 6523 defines the International Code Designator (ICD)

• Official list at http://iso6523.info/icd_list.pdf
• More usable list at https://docs.peppol.eu/poacc/billing/3.0/codelist/ICD/
• Can be resolved at http://oid-info.com/, eg http://oid-info.com/get/1.3.88
• Described at Wikidata: https://www.wikidata.org/wiki/Q28908940
• There is no separate prop on Wikidata because it's subsumed by https://www.wikidata.org/wiki/Property:P3743 ITU/ISO/IEC object ID (oid) with prefix 1.3. Eg ICD=0088 is mapped to 1.3.88
• oid can be used as URN, eg urn:oid:1.3.88
• Because ICD is an object identifier, it is used for a lot more than organizations and registered companies: also locations (GS1 GLN), goods (GS1 GTIN), banks, ATMs, application layer protocols, IP address registrants, file & document formats, information objects, local/remote procedures, etc etc.

@danbri or @alex-jansen could you capture some of the above info at https://schema.org/iso6523Code?
In particular this is important:

• To match OID usage, leading zeros should NOT be included in in the ISO 6523 code
• What's the separator between ICD and OI? Is it : or something else?
• Please give some examples (I'll try to give examples here and in the related issue)

@alex-jansen, where did you see "9910+9920-9957 for European vatID"? Please describe your source, and give some examples. Thanks!

@danbri and @alex-jansen please answer the questions in my first comment.
In particular, is the delimiter :? Where is this documented?

[MatthiasWiesmann]

Vladimir, this is documented inside the ISO/IEC 6523-1 standard. To characters are given as examples of separators, colon and slash. Given the prevalence of slashes in web-content, colon seems safer. Colon also seems to be the commen format in EDI systems that leverage ISO 6523.

[danbri]

If the ISO spec is not public it could be good to improve the documentation we have here (within appropriate limits).

[MatthiasWiesmann]

I will prepare a change with improved documentation.

I eventually found a mostly usable ICD list here:

https://ec.europa.eu/digital-building-blocks/wikis/display/DIGITAL/Registry+of+supporting+artefacts+to+implement+EN16931#RegistryofsupportingartefactstoimplementEN16931-Codelists

It's tricky to get the sheet as the URLs are broken:

1. Pick the latest "Full listing" from lower down on the page
2. Copy its URL
3. Remove the query string parameters
4. Browse the new URL
5. Open the sheet
6. Go to the EAS tab

There is also an ECD tab that is missing the 9XXX ones (VAT numbers) but seems to have others, like 0141, which is missing from the EAS tab. I found more numbers in other places but discovered they had been deprecated (first list on that page).

So far, I've yet to find a definitive list to work from.

I also altered some of the names to make them more findable. e.g. I added "UK" to 9932, "DUNS" to 0060, "LEI" to 0199 and "United States" to 9959. I have a nice searchable dropdown for my clients :-)

[MatthiasWiesmann]

I uploaded an proposal with improved documentation here: https://iso6523-dot-schemadotorg1.ew.r.appspot.com/Organization

Besides the documentation for the iso6523Code field, I also completed the examples.

please have a look and let me know if it helps.

[Tiggerito]

I like it.

There's a funny (-1) in the link.

It would be nice if it could reference a source for the UIDs. If I had trouble finding them, the average website developer would struggle.
