Application Packaging Standard

The Application Packaging Standard (APS) is a standard that defines a technology for integrating application software with hosting platforms. Integration of an application with hosting platforms is implemented by creating an "APS package" for this application, and APS package deployment creates an "APS application".
Participants.
APS involves three types of participants into the integration process:
Versions.
APS went through two stages.
APS 1 emerged as a way for creating predominantly two types of APS packages and respectively two types of APS applications:
APS 2 added flexibility to integrate applications not only with hosting platforms but also with each other. APS 2 makes it possible to create custom user interface in hosting platforms for managing the integrated applications.
Implementations.
The following web hosting platforms allow installations of APS packages:
Application catalog.
APS packages are available for download at application catalog.
ISVs can make their applications publicly available by uploading them to this catalog.
