RE: "a lookup table of UBL:TaxCategory items"

Xalgorithms Foundation has created a general purpose method and a working reference implementation for table lookups for any and all fiscal rules. Where rule-makers and rule-takers implement the UBL schema (which our sample use cases for commerce and trade do) then transaction data can be directly used to filter fiscal rules that are 'in effectâ for given dates/times and jurisdictions, and that are âapplicableâ when particular circumstantial facts are present. Here is a demo video of the line-by-line unit test for the base rate of a value added tax -- pointed at the time where the various base rates are shown relative to the ISO 1366-1 (country) and 1366-2 (sub-country) jurisdictions. In relation to 'trade policy 3.0' level there are some interesting explorations underway:

The OECD Observatory for Public Sector Innovation has a forthcoming report: "A Rules-as-Code Primer: New rules for a new era" https://oecd- opsi.org/new-rules-contributions/Â which states: "Through the non-for-profit Xalgorithms Foundation, economist Joseph Potvin, and informatics technologists Don Kelly and William Olders have designed a free/libre/open source method and general-purpose online service that enables any organization or individual to publish, discover, fetch and prioritize rules in the form of JSON control tables. This is done in a simple tabular style that is readable by non-technical people and directly usable by computers for data filtering and transformation. Once any rule or reference table is expressed in this ârules-as-dataâ form, it can be directly exchanged among, or embedded into, any application built in any programming language and either used natively, or auto-transcribed into ârules as codeâ form. This promises to create, in essence, an "Internet of Rules". The design is usable with both 'single window' or 'distributed' architectures for trade, commerce, logistics and value-chain administration; whatâs more, it is being implemented for a wide diversity of use cases other than trade facilitation. Trade, fiscal, and related statutes can include an attached 'schedule' with control table(s), or they can employ an âincorporation by referenceâ clause to authoritative online sources where they are maintained."

I and others in the 100% free/libre/open source Xalgorithms community will be happy to collaborate with anyone in the UBL community to operationalize other types of fiscal instruments in this way.

David,

do you mean something like this? These are the same list .. jsut different representation .. for PEPPOL Invoice/CreditNote documents based on the EU standard.

Onderwerp: [ubl-dev] Does any (sales)tax authority publish lists of UBL formatted taxes?

Â

Rather than reinventing the wheel, I was wondering of any Tax authority, either national (say HMRC) or regional (say Peppol or EU), or come to that anyone, publish lists of current Tax Categories, preferably in UBL format, but other formats that could be converted into a lookup table of UBL:TaxCategory items?

Â

If so does anyone have any URLs that point to them?

Â

Thanks in advance
