Dev:Common Concepts

Common concepts to all railML® schemas

Common is a pseudo subschema to cover general aspects or aspects interfering different subschemas. Some general concepts about handling railML files are summerized on the following wiki-sites:

• Conventions for railML files (file name extensions, compressed files, and other)
• Handling identities (id values)
• Local versus web-based validation (XML catalogs and XML namespaces)
• Versioning policy (version numbers, versioned XML namespaces)
• Officially released versus developer version (Homepage, Subversion)
• Discussed versus agreed features (Newsgroup, Trac Tickets)
• XML Syntax issues (Attribute delimiters, Character references)
• Using "xs:any" elements, "anyAttribute"s and "other:anything" enumeration values for enhancing the railML files with your special needs
• Using content libraries and fully validating without any error or warning messages
• Changes sorted by released versions
• CO:Codelists
