Schema Proposal

1. For "network-resource", add string "network-type" attribute.
   1. Has enumerated values e.g. ETH topology or OTN topology.
2. For "pnf", add boolean "is-abstract" attribute.
   1. Has "false" value by default.
   2. Set to "true" value to represent abstract node, i.e. group of PNFs abstracted and presented as a single node by domain controller.
3. For "logical-link", new enumerated values for "link-type" attribute, e.g. intra optical domain, inter optical domain, or inter operator domain.
4. For "p-interface", add integer "inter-layer-lock-id", "inter-domain-plug-id" attributes.
   1. Has discovered values based on IETF specifications, for correlation between related objects in ETH topology and OTN topology.
   2. Add EdgeRule to represent p-interface to p-interface relationship described by "inter-layer-lock-id" attribute.
5. For "p-interface", new enumerated values for "interface-type" attribute, e.g. "Tunnel Termination Point".
6. Add new resource "uni".
   1. Has termination point and cvlan attributes.
   2. Add EdgeRule to represent uni to p-interface relationship.
7. Add new resource "label-restriction".
   1. Has discovered vlaues for label restriction attributes e.g. priority, range type, label start, label end.
   2. Add EdgeRule to represent te-link-attributes to label-restriction relationship. 
8. Add new resource "te-link-attributes"
   1. Has discovered values for te link attributes, e.g. isAbstract, link protection type, access type.
   2. Add EdgeRule to represent logical link to te-link-attibutes relationship.
9. For "pnf", add new attribute "supporting-node" attribute.
   1. Has discovered value based on ETH topology and OTN topology
10. Add new resource "tunnel-termination-point"
    1. Has discovered values for TTP attributes, e.g. TTP-id, admin-status, oper-status, protection-type, inter-layer-lock-id.
    2. Add EdgeRule to represent tunnel-termination-point to p-interface relationship.

Discussion of Impacts

1. pnf is also involved in other use cases. What is the impact of introducing the "abstract node" concept?
2. link-type values for logical-link need to be modeled. What is the impact of introducing new values?
3. interface-type values for p-interface need to be modeled. What is the impact of introducing new values?
