Current implementation is designed to work in close cooperation with the [[Sugar Network]] installing dependencies required by Sugar Activities. To make it possible, Sugar Network supports a [http://network.sugarlabs.org/hub/?projects&packages list of metadata entries] for all required packages on major GNU/Linux distributions (to support not only XO laptops). Each activity, which requires dependencies, should mention proper metadata entry names in the {{Code|requires}} tag in the {{Code|activity.info}} file. Client side startup code will process this dependency list and ask PackageKit to install packages via packagekit-presolve-backend.

While working, packagekit-presolve-backend will use public [[Platform_Team/Sugar_Network/API|Sugar Network API]] (look for development API server for recently implemented functionality). The regular operations called from the API server are the following:
<div id="GET_packages"></div>
'''GET''' /packages/OLPC/''OLPC-RELEASE''/''METADATA-ENTRY-NAME''
'''GET''' /packages/OLPC/''OLPC-RELEASE''/''METADATA-ENTRY-NAME''
Where {{Code|PATH}} is either relative or absolute path to the targeting rpm on the same server.
Where {{Code|PATH}} is either relative or absolute path to the targeting rpm on the same server.
<div id="GET_packages_updates"></div>
'''GET''' /packages/OLPC/''OLPC-RELEASE''/updates
Returns JSON list of package names to fetch updates for. Sugar Network server will dynamically generate response according to HTTP {{Code|If-Modified-Since}} header value.
