org.apache.sling.installer.api.InstallableResource
A piece of data that can be installed by the {@link OsgiInstaller}Currently the OSGi installer supports bundles and configurations, but it can be extended by additional task factories supporting other formats. The installable resource contains as much information as the client can provide. An input stream or dictionary is mandatory everything else is optional. All optional values will be tried to be evaluated by the OSGi installer. If such evaluation fails the resource will be ignore during installation. If the client provides a configuration it should use the resource type {@link #TYPE_PROPERTIES}. Otherwise the resource type {@link #TYPE_FILE} should be used. These two generic typesare transformed by resource transformer services to the appropriate resource type like bundle or configuration etc. This frees the client from having any knowledge about the provided data. However, if the client has the knowledge about the data it can provided a specific resource type. The provider should provide a digest for files (input streams). The installer will calculate a digest for dictionaries, regardless if the provider provided a dictionary.

        final String[] types = new String[] {InstallableResource.TYPE_CONFIG,
                InstallableResource.TYPE_PROPERTIES,
                null, "zip"};

            final InstallableResource instRes = new InstallableResource("1",
                    null, getSimpleDict(), null, types[i], null);


            final InternalResource ir = InternalResource.create(SCHEME,
                    instRes);
