The OpenVX-Registry repository contains the OpenVX API and Extension Registry, including specifications.

It is also used as a backing store for the web view of the registry at ; commits to the master branch of this repository will be reflected there.

In the past, the OpenVX registry was maintained in a public Subversion repository. The history in that repository has not been imported to github, but it is still available at .

Interesting files in this repository include:

  • index.php - toplevel index page for the web view. This relies on PHP include files found elsewhere on and so is not very useful in isolation.
  • api/ - OpenVX header files
  • extensions/ - OpenVX extension specifications, grouped into vendor-specific subdirectories.
  • sample/ - OpenVX sample implementations.
  • schema/ - OpenVX XML Schema
  • specs/ - OpenVX specification documents.

Adding Extension Specifications

Extension specification documents can be added by proposing a pull request to master, adding the specification HTML files under extensions/extension_name/ . You must also:

  • Add a link from the extensions section of index.php to the extension document, so it shows up in the web view.
