Abstract

Methods, systems, and computer program products for improving installation of software packages using an incremental conditional installation process (and optionally, caching of installation components). An object model is disclosed which enables specification of the conditional installation information as one or more elements of the model (and therefore of an object, document, etc., which is created according to the model). Conditional installation information may be defined at a suite level and/or at a component level. The identified checking process then executes to determine whether the corresponding suite or component should be installed. One or more components may be cached, if desired. Resource utilization is improved using the conditional installation and optional caching techniques, enabling reductions in disk space usage, CPU consumption, and/or networking bandwidth consumption.

Claims

1. A method of improving installation of software packages, comprising steps of:

defining an object model representing a plurality of components of a software installation process, wherein the defined model enables specifying conditional installation information for the components; and

populating the object model to describe a particular software installation package, wherein the conditional installation information is populated with information to describe conditional installation scenarios.

2. The method according to claim 1, further comprising steps of:

using the conditional installation information of the populated object model during an installation of the particular software installation package to determine whether the installation should be performed; and

performing the installation if so.

3. The method according to claim 1, further comprising the step of instantiating a plurality of objects according to the defined object mode, each of the instantiated objects corresponding to a selected one of the components of the software installation process, and wherein the populating step populates the instantiated objects.
