The OASIS Universal Business Language (UBL) defines a generic XML interchange format for business documents that can be restricted or extended to meet the requirements of particular industries. Specifically, UBL provides the following:
A suite of structured business objects and their associated semantics expressed as reusable data components and common business documents.
A library of XML schemas for reusable data components such as “Address”, “Item”, and “Payment”—the common data elements of everyday business documents.
A set of XML schemas for common business documents such as “Order”, “Despatch Advice”, and “Invoice” that are constructed from the UBL library components and can be used in generic procurement and transportation contexts.
This Committee Note provides an alternative non-normative representation of the UBL XML schemas for use in systems supporting Abstract Syntax Notation 1 (ASN.1), ISO/IEC 8825-1.
The keywords MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD, SHOULD NOT, RECOMMENDED, MAY and OPTIONAL, when they appear in this document, are to be interpreted as described in [RFC2119].
UBL 2.1 continues the practice, adopted at the beginning of the UBL effort, of creating its normative XML specifications using W3C Schema (XSD) syntax. Alternative representations of the same content are generated directly from the XSD and are intended to implement the same document instance constraints.
Alternative representations of the same content are technically non-normative.
The UBL ASN.1 specification provides an alternative schema definition for UBL documents in accordance with ITU-T X.680-X.693 [ASN.1]. The UBL ASN.1 specification defines the same UBL documents as the UBL XSD schemas that constitute the normative definitions of valid UBL documents. The UBL ASN.1 XML specification enables ASN.1 tools to be used for UBL transfers, and in conjunction with the ASN.1 Packed Encoding Rules, it provides a specification for an efficient binary encoding of UBL messages.
The ASN.1 modules were created using a tool from OSS Nokalva that conforms to ITU-T Recommendation X.694 | ISO/IEC 8825-5 for converting XSD Schema to ASN.1.
This software-generated summary documentation file describes the contents of the ASN.1 schemas for UBL 2.1 in a human-readable format in HTML:
The following ASN.1 schemas are for the UBL 2.1 document models:
The following schemas are not addressed directly for validation of a UBL document but are referenced from the document schemas in support of their requirements:

Release of this package to the public marks the beginning of its first public review of Committee Note 03. The UBL Technical Committee actively solicits input from the user community regarding this release. See Status at the beginning of this document for procedures to be used in submitting comments to the Committee. Note that in accordance with OASIS policies regarding intellectual property, the UBL TC cannot accept input from persons outside the UBL TC (including OASIS members) unless it is submitted via the comment list.
This OASIS Committee Note is published as a zip archive in the https://docs.oasis-open.org/ubl/UBL-2.1-ASN.1/v1.0/cn03/ directory. Unzipping this archive creates a directory tree containing a master DocBook XML file (UBL-2.1-ASN.1-v1.0-cn03.xml), a generated hypertext version of this file (UBL-2.1-ASN.1-v1.0-cn03.html), a generated PDF version of this file (UBL-2.1-ASN.1-v1.0-cn03.pdf), and a number of subdirectories. The files in these subdirectories contain the various components of this release. A description of each subdirectory is given below. Note that while the UBL-2.1-ASN.1-v1.0-cn03.xml file is the “original” of this specification, it may not be viewable in all currently available web browsers.
