Abstract

A system links architecture neutral code downloaded to a resource constrained computer. The code may be separated into one or more packages having one or more referenceable items. The system maps the one or more referenceable items into corresponding one or more tokens; orders the tokens to correspond to a run-time mode; downloads the packages to the resource constrained computer; and links the packages into an executable code using the ordered tokens.

Claims

1. A method for downloading code to a resource constrained computer, the code being separable into at least one package having at least one referenceable item, comprising:

forming the package;

forming a mapping of the referenceable item to a corresponding token; and

providing the package and the mapping.

2. A method for linking code downloaded to a resource constrained computer, the code being separable into at least one package having at least one referenceable item, comprising:

receiving the package;

receiving a mapping of the referenceable item to a corresponding token; and

linking the package using the mapping.
