The reference set of AIXM 5.1 Business Rules is made available in the form of an Excel file, that contains both the SBVR formulation and, where available, the Schematron encoding of the rule. This Excel file is available here: www.aixm.aero/page/business-rules.
XML file (new)
Explain here the content and structure of the XML file. Also explain how the XSLT provided can be used to transform the XML into a table, with a structure very similar to the previous Excel format. The HTML table can be in fact imported in Excel, if necessary.Clicking on the XML button of the AIXM BRM web application allows exporting rules into an XML file:
The new XML export structure follows the schema defined in the AIXM-BR-SBVR.XSD file, which matches with the following structure:

The XSL stylesheet is used to convert the AIXM-BR-SBVR.xml file into a single HTML table, where templates are instantiated. For that, an XSLT compatible tool must be used, like an XML editor or simply opening the exported file with you Internet Explorer browser. The result is similar to opening the original Export (in XML for Excel format) in Excel:
Profiles
As explained in the Introduction, not all systems apply the same rules, in particular when it comes to minimal data - what is critical for a system might be of no relevance for another system. The error level of a rule may also depend on the profile.
The profile to which a rule belongs is indicated starting from the second column in Excel or through the Profile child element of each rule/template/instance in the XML export. Two error levels are used in the profiles ("Error" or "Warning").
...
This profile will contain a selection of AIXM features and business rules that can be used in order to verify the correctness and completeness of Digital NOTAM data sets. This shall be included in the Digital NOTAM Event Specification (starting with version 2.0).
Event_FAA profile
This profile will contain rules that are specific to the Digital NOTAM encoding scenarios of FAA (FNS-NDS) system. Such rules refer to an FAA scenario number.
