XML Schema

• XML Schema: defines the rules for the XML file format
• XSL stylesheet (used to extract information shown on the Schema documentation page)

XML Stylesheets

Stylesheets could be used to strip out the metadata or to convert into another file format. No examples have yet been described here.

Examples and Case Studies

• basic example: Note that, for clarity, only one row of data is shown. This is probably a very good example to use as a starting point for creating XML files with a text editor.
• bimodal-test1.xml: Simulated SAS data to test size distribution calculation routines.
• dry chick collagen: illustrates the minimum information necessary to meet the requirements of the standard format
• AF1410 steel: SANS study using magnetic contrast variation (with multiple samples and multiple data sets for each sample)
• cansas1d-template.xml: This is used to test all the rules in the XML Schema. This is probably not av very good example to use as a starting point for creating XML files with a text editor since it tests many of the special-case rules.
