iText kernel.jar Source Code
kernel.jar is a component in iText Java library to provide low-level functionalities.
iText Java library allows you to generate and manage PDF documents.
The Source Code files are provided together with the JAR file in the binary packge like iText7-Core-7.1.4.zip. You can download it at iText 7 Core Download site.
You can compile it to generate your JAR file, using kernel.pom as the build configuration file.

/**
* The schema registry keeps track of all namespaces and aliases used in the XMP
* metadata. At initialisation time, the default namespaces and default aliases
* are automatically registered. <b>Namespaces</b> must be registered before
* used in namespace URI parameters or path expressions. Within the XMP Toolkit
* the registered namespace URIs and prefixes must be unique. Additional
* namespaces encountered when parsing RDF are automatically registered. The
* namespace URI should always end in an XML name separator such as '/' or '#'.
* This is because some forms of RDF shorthand catenate a namespace URI with an
* element name to form a new URI.
* <p>
* <b>Aliases</b> in XMP serve the same purpose as Windows file shortcuts,
* Macintosh file aliases, or UNIX file symbolic links. The aliases are simply
* multiple names for the same property. One distinction of XMP aliases is that
* they are ordered, there is an alias name pointing to an actual name. The
* primary significance of the actual name is that it is the preferred name for
* output, generally the most widely recognized name.
* <p>
* The names that can be aliased in XMP are restricted. The alias must be a top
* level property name, not a field within a structure or an element within an
* array. The actual may be a top level property name, the first element within
* a top level array, or the default element in an alt-text array. This does not
* mean the alias can only be a simple property. It is OK to alias a top level
* structure or array to an identical top level structure or array, or to the
* first item of an array of structures.
