Use Case Number

Init1dbw6.U8

Brief Description

caB2B relies on establishing/identifiying relationships between concepts (entities) and/or properties (attributes) exposed through a service's implementation models (currently registered in caDSR/advertised on caGrid). For instance, we need to be
able to identify (or compute) Gene (entity from Model A) and MyFavoriteGene
(entity from Model B) are representing identical concepts, even when the entities are not named the same. Furthermore that Gene.entrezGeneId property (attribute from model A) and MyGene.geneEntereId (attribute from model B) are representing the same property/attribute for the given concept.

Currently NCIt concept mappings stored in the caDSR for the Object Classes and CDEs are leveraged to
identify such relationships.  These CDE mappings are the simpilest to map across models because the CDE means that the physical database representation (syntatxsyntax) is the same in the two models and can be directly aggregated.

The new SI should continue to provide services and processes for us to be able to identify such relationships. In accordance with ECCF, the services/processes should at the minimum leverage the traceability (computable) among different levels of models (CIM->PSM) and compliance
among model representations (PSM<>PSM). If the service's semantic profile asserts that the service is conformant to all or part of a particular CIM>PIM->PSM,  caB2B should be able to easily discover this equivalence.

Actor(s) for this particular use case

Cancer Researcher

Pre-condition
The state of the system before the user interacts with it

A set of services particular concept of interest has been identified via the Metadata Category. terminology browser or metadata browser.
Class/entities in models have been associated with common concepts. 

Post condition
The state of the system after the user interacts with it

The results from the cross-service model discovery operation are aggregated and presented to the user.

Steps to take
The step-by-step description of how users will interact with the system to achieve a specific business goal or function

1. The Cancer Researcher selects the concept of interest and the operation (such as as  "querydiscover related models") he would like to invoke on the selected services
2. The SI services are invoked and results are returned
3. The results are aggregated based upon the Metadata Categorythe matching entities and levels of entities in the models. For example, models or portions of models that are conformant at the CIM level are evident, at the PIM level, and at the PSM level and are self-evident in the results.
4. The aggregated results are returned to the user

Alternate Flow

Fit criterion/Acceptance Criterion 
How would actor describe the acceptable usage scenarios for the software or service that meets the actor's requirement?

None Only Models where matching classes, attributes and associations are returned by the operation.
