RE: [tosca] Proposal for TOSCA repositories grammar

Thanks Tal and Adam, this is a very good discussion. Iâd love to see proposals for how to make repositories âfirst class objectsâ in TOSCA.

Thanks,

Chris

Could you use a internal URI scheme as the repository URL, like "turandot:"?

Sure, if I extend my whole URL handling library. :) I actually can do that in my specific case, but I'm sure that many orchestrators cannot, and in any case I think it should be supported by TOSCA grammar rather than requiring orchestrators to implement difficult workarounds.

it really would like to know what type of repository it is and have properties or at least metadata.

Metadata is the ultimate workaround! In the case of artifacts -- they are typed, so we can use actually modeled data: TOSCA properties (but because TOSCA is object-oriented you would need all artifact types to import from that base type, which is not always possible). These are all workarounds. I think that because artifact management and import management are so intrinsic to TOSCA it should be well-defined in the grammar itself.

I'm sure we all agree that TOSCA repositories are quite ineffective right now and can use some of our attention.
