These specifications consists of several components which can be accessed on this website. Here follows a short introduction of each part and its purpose. They can all be accessed from the main page.

Documentation

The main BIS document (Business Interoperability Specification) which describes a business process and the functionality that it supports. It gives a high level view but also goes also into selected parts of the business message by describing common examples, datatypes and code lists. A business process consists of a series of transaction that are exchanged between the business parties in the described sequence. Technical details for each transaction are provided in the following sections, syntax, rules and code lists.

NOTE:It should be noted that these specifications are a re-publication of the same specifications published by OpenPeppol with a few customized non-normative examples that show typical values used in Singapore. The schematron rules are also re-published. In the unlikely event of discrepencies, the OpenPeppol schematron is to be considered normative.

Syntax

An description of each XML element and attribute in the technical format used to represent the business document
