Subject: RE: Range type: upper_bound constraint to be "greater than or equal to" instead of "greater than"?
Hi Gabor, Good catch. Weâll get this corrected in TOSCA Version 2.0. Weâll also discuss whether we need to correct this in TOSCA Simple Profile for YAML v1.3 Thanks, Chris From: tosca@lists.oasis-open.org <tosca@lists.oasis-open.org>

äè Arturo Martin De Nicolas Hello Gabor, Yes, I agree with you. In fact it is not only SOL001 using it. Even the very TOSCA spec uses [ 1, 1] as the default range for requirements occurrences: The following is the list of recognized keynames for a TOSCA requirement definition:
It should be fixed. BR, Arturo From: tosca@lists.oasis-open.org <tosca@lists.oasis-open.org>
On Behalf Of Marton, Gabor (Nokia - HU/Budapest) Dear TOSCA Experts, we ran into this issue recently. The specs (both v1.2 and pre-v1.3) says: 3.3.3.1 Grammar
TOSCA range values have the following grammar:
In the above grammar, the pseudo values that appear in angle brackets have the following meaning:
Â
lower_bound: is a required integer value that denotes the lower boundary of the range.
Â
upper_bound: is a required integer value that denotes the upper boundary of the range. This value MUST be
greater than
lower_bound. Instead of âgreater thanâ, the constraint should better be âgreater than or equal toâ as a range like â[ 1, 1 ]â is a valid range. It is also used in the ETSI NFV SOL001 specifications, e.g.: tosca.nodes.nfv.Vdu.Compute: derived_from: tosca.nodes.Root description: Describes the virtual compute part of a VDU which is a construct supporting the description of the deployment and operational
behavior of a VNFC properties: .. capabilities: virtual_compute: type: tosca.capabilities.nfv.VirtualCompute occurrences:
[ 1, 1 ] .. .. Do you agree with the conclusion? Kind regards, GÃbor |
