Package osid.installation

Title Installation Open Service Interface Definitions

Version 3.1.0

Description

Package	osid.installation
Description	The Installation OSID describes two categories of services. One service is to find, retrieve and manage installation packages in remote repositories, or `Depots`. The other service is to manage installations (downloaded packages) on `Sites`. Sites are generally, but not required to be, on local disk. InstallationPackages `InstallationPackages` define a set of core data and map to an independently retrieved and managed data stream. The data stream may be an archive file of a certain format. A `InstallationPackage` may include multiple formats. `InstallationPackages` also may have other packages on which it depends for operation. Each version of a software package is a separate `InstallationPackage` identified by a separate `Id`. Version chains may be defined to communicate newer available versions. Installations An installed package on a `Site` is an `Installation`. `Installations` are similar to `InstallationPackages` with a different set of core data and no access to the archive stream. `Installations` may also have dependencies and versioning. Methods are defined to check for updates available in a `Depot` for an `Installation`, at which time the consumer may elect to install the new `InstallationPackage` `Id` for the updated version. Depending on whether a provider keeps the older version around, delete operations may be available for outdated versions and allow for dependency management across versions. `Sites` are assumed to be fixed to the runtime environment and are not manageable through the Installation OSID. As such, `Sites` are not modeled as `OsidCatalogs` and a single `Installation` may belong to only one `Site`. Depot Cataloging `InstallationPackages` are organized into `Depots` for categorization and federation using the OSID hierarchy pattern. Dynamic virtual `Depots` may be created by filtering on various `InstallationPackage` attributes. Versions The Installation OSID defines an `OsidPrimitive` for a `Version`. A `Version` describes a version number. Orchestration The Installation OSID may be orchestrated with a Configuration OSID to retrieve or manage installation configurations. Sub InstallationPackages The Installation OSID contains an Installation Batch OSID for managing `InstallationPackages` and `Installations` in bulk.

InstallationPackages

InstallationPackages define a set of core data and map to an independently retrieved and managed data stream. The data stream may be an archive file of a certain format. A InstallationPackage may include multiple formats. InstallationPackages also may have other packages on which it depends for operation. Each version of a software package is a separate InstallationPackage identified by a separate Id. Version chains may be defined to communicate newer available versions.

Installations

An installed package on a Site is an Installation. Installations are similar to InstallationPackages with a different set of core data and no access to the archive stream. Installations may also have dependencies and versioning.

Methods are defined to check for updates available in a Depot for an Installation, at which time the consumer may elect to install the new InstallationPackage Id for the updated version. Depending on whether a provider keeps the older version around, delete operations may be available for outdated versions and allow for dependency management across versions.

Sites are assumed to be fixed to the runtime environment and are not manageable through the Installation OSID. As such, Sites are not modeled as OsidCatalogs and a single Installation may belong to only one Site.

Depot Cataloging

InstallationPackages are organized into Depots for categorization and federation using the OSID hierarchy pattern. Dynamic virtual Depots may be created by filtering on various InstallationPackage attributes.

Versions

The Installation OSID defines an OsidPrimitive for a Version. A Version describes a version number.

Orchestration

The Installation OSID may be orchestrated with a Configuration OSID to retrieve or manage installation configurations.

Sub InstallationPackages

The Installation OSID contains an Installation Batch OSID for managing InstallationPackages and Installations in bulk.
