SWIDFromXSD 1.0.0

Procedures to generate the source files:

Gather source XSD files

• Create a folder xsd in the root directory of the project.
• Download these files to that xsd directory
  • http://standards.iso.org/iso/19770/-2/2015-current/schema.xsd
  • https://csrc.nist.gov/schema/swid/2015-extensions/swid-2015-extensions-1.0.xsd
  • For newer versions, check

Install LinqToXsdCore

This project uses LinqToXSDCore to generate the C# code files. dotnet tool install LinqToXsdCore -g

Create LinqToXsdCore namespace config files

These commands are run from the root directory of the project with the XSD files downloaded to .\xsd. linqtoxsd config -e .\xsd\iso-19770-2-schema-1.0.xsd .\xsd\swid-2015-extensions-1.0.xsd This will output LinqToXsdConfig.config

Change generated namespaces in LinqToXsdConfig.config

Convert XSD to C#

linqtoxsd gen .\xsd\iso-19770-2-schema-1.0.xsd .\xsd\swid-2015-extensions-1.0.xsd -c .\LinqToXsdConfig.config -o .\src\

Convert Line endings of Files to Unix (LF)

Replace lang.TypeDefinition with null

There is a bug in either the schema or during conversion that results in iso-19770-2-schema-1.0.xsd.cs using a type that does not exist. There are two references to lang.TypeDefinition that need to be replaced with null.

Install XObjectsCore from Nuget

Useful library methods

SoftwareIdentity swid = SoftwareIdentity.Load("/path/to/swidtag"); byte[] bytes = Convert.FromHexString(string);
