Abstract:
Since February 1st 2005, millions of invoices have been exchanged between the private sector and the public sector in Denmark. This paper focuses on real life problems, experiences and solutions with syntactical and semantical validation of millions of electronic invoices. Localization and documentation for regional and national use is a massive and important assignment. I.e. decisions on the use of identifiers have to be specified and local payment methods must be mapped to the international standard. The result is a message with many internal integrity constraints that cannot be validated with the UBL schemas alone. In order to provide even stronger validation, non-normative supplementary schemas have been developed. These schemas perform stronger validation based on decisions about the use of national identifiers for companies and persons. In addition to the use of XML schema – Schematron is used for the validation of internal referential integrity constraints. Experiences and theoretical considerations on the localization of international vocabularies are discussed.
