Abstract From the Canadian patent

A metadata repository for use in an integrated development environment is provided. The metadata repository is layered to define levels of common behaviour useful to different types of application development tools. The most general use tools have access to metadata at the level of simple constructed types; more specialised tools have access to components that contain properties of a target language; highly specialised tools have access to composed partitionable part metadata that can be used for constructing distributed applications.

Why it's free to use

  • Filed March 27, 1997 and granted February 20, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 27, 2017.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 27, 2019.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
