| [[Sugar Network]], in its attempt to provide GNU/Linux-distribution-agnostic launches of activities, it provides and supports packagekit-backend-presolve users. | | * [[Sugar Network]] [[Platform_Team/Sugar_Network/API#Support_packagekit-backend-presolve|API server]]. |
| | |
| API server provides the following kinds of urls: | |
| | |
| * {{Code|<nowiki>http://api-devel.network.sugarlabs.org/packages</nowiki>}}<br>list all supported platforms;
| |
| * {{Code|<nowiki>http://api-devel.network.sugarlabs.org/packages/</nowiki><PLATFORM>}}<br>list all supported packages for a particular platform;
| |
| * {{Code|<nowiki>http://api-devel.network.sugarlabs.org/packages/</nowiki><PLATFORM>/<PACKAGE>}}<br>pre-solved dependency graph for a particular package.
| |
| | |
| Where:
| |
| | |
| * {{Code|PLATFORM}}<br>one of supported packagekit-backend-presolve platforms, e.g., OLPC-13.0.1;
| |
| * {{Code|PACKAGE}}<br>a name of the particular package.
| |

| In order to support distribution-agnostic launches, [[Sugar Network]] supports a metadata ''database'' for all packages that are being used as dependencies for activities it provides (see ''Packages'' project using one of the existing [[Sugar_Network#Try_it|Sugar Network clients]]). Every entry in the ''database'' contains a map of native package names for a particular GNU/Linux distribution. So, activities mention only the ''database'' entry name as a dependency. [[Sugar Network]] will automatically generate dependency graphs for packagekit-backend-presolve using the ''metadata'' database. Afterwards, on the launch side, the ''database'' entry name will be resolved to a package name according to the local distribution and it will be passed to the PackageKit (on XO laptops, packagekit-backend-presolve will be used; on regular platforms, the default PackageKit back-end is used).
