honourPropagationConstraintsInContextSharing

protected boolean honourPropagationConstraintsInContextSharing

By the default the system honour the propagation constraints so this variable is initialised as true. To revert a previous operation or for particular a maintenance we could request to the service do not honour the propagation constraints but under certain conditions and with some limitation only. These limitation are required to keep the system in a consistent state. In fact, this directive is only valid for Resources and IsRelatedTo relations. We need to take in account that to add an IsRelatedTo to a context always the source and target Resources must be in such a Context. Please also take into account that adding a Resource to a context always imply to honour the propagation constraints of ConsistsOf relations. In fact, a resource must be characterised least by one facet in any context it belongs. Giving that we cannot made assumption on which facets must be used. A way could be to consider just the facets are mandatory for such a Resource Type, but the type could not have mandatory facets (even every Resource Type in the gCube Model has one mandatory facet). As counterpart, when a Resource is removed from a Context all the facets charactering it must be removed. This option can also be used in conjunction with ElementManagement.dryRun=true. This allow to simulate a sharing operation which requires do not honour the propagation constraints.
