Subject: [sca-policy] NEW ISSUE:
Need more precision on when policies in a policySet are in effect
TARGET:
SCA Policy Framework
DESCRIPTION:
It is not clear whether policies in a policySet that are not referenced by the
list of required intents are always applicable.
What exactly is the effect of having a list of required intents? Are the
intentMaps in the policySet that are not referenced by the list of required
intents ignored? Or is the semantic that all parts of the attached policySet
always apply, and the list of required intents is used only for overriding the
defaults in the contained intentMaps?
How to handle standalone policies should also be addressed while addressing
this issue.
In particular, consider the following two cases and the questions they raise:
A> There are no required intents declared, and an attached policySet
contains some standalone policies and some intentMaps
Questions:
- Do standalone policies in the policySet apply?
- Should all the intentMaps contained in the policySet be considered? Should
the policies for the default qualifier in each considered intentMap be applied?
B> There are required intents declared, and an attached policySet includes
intentMaps for some of the required intents, intentMaps for some other intents,
and also some standalone policies.
- Do standalone policies in the policySet apply?
- Should intentMaps pertaining to intents that are not listed as required be
considered? For each such intentMap, should the policies for the default
qualifier be applied?
PROPOSAL: none
PROVENANCE: SCA-226
