Summary of requirement pre-interview, by Reviewer:

The primary actor for this requirement is Information Modelers. The goal of this requirement is leveraging the LexGrid model with Semantic Web standards and specifications. The LexRDF model will map the LexGrid model elements to corresponding constructs in W3C specifications. The data in the LexGrid will translate into RDF triples. LexEVS will query the RDF triples with Semantic Web query language.

Recommended Next Step Enter one: Follow-up interview, Observe, Use Case Template (text), Use Case Model (formalized/UML diagram), Group Discussion, Prototype, Waiting Room

Script / Question

Information/Response

1

Hello, my name is NAME. I am calling you today because NCI and caBIG are working toward a new and improved version of the semantic infrastructure to better support integration scenarios.
Our first step was to organize requirements collected over the past year. Your organization has expressed a requirement/need for BRIEF STATEMENT OF USER REQUIREMENT.  This has been identified as potentially a critical component to support application/data and service integration, and we need more information in order to enable us to meet this requirement.
Do you have about 30 minutes to talk about this?

Yes.

2

Do you have any solution integration needs? If so, what are they? Have you envisioned new ways of interacting with existing or new parts of the semantic  infrastructure?
(prompt to elicit changes/new ways of using the infrastructure)

1. The LexRDF model should translate the LexGrid model elements to corresponding constructs in W3C specifications such as RDF, OWL and SKOS.
2. The terminological information represented in LexGrid should be translated into RDF triples.
3. LexEVS should leverage the Semantic Web Tools (e.g., SPARQL) and technologies into LexGrid.

3

Are there any business changes you are assuming we will be able to deal with? 
(prompt to elicit changes/new ways of using the infrastructure) 

Focusing on changing the backend of LexGrid from relational database to RDF triple stores. No impacts on the user interface. Providing better supports (e.g., faster query speed).

4

Are there any capabilities you are expecting to be available to support your needs? 
(prompt to elicit expectations/dependencies)

Notes that identify capabilities, tools, and/or services expected

5

Do you use any of the existing software/services? If so, what do you like or dislike about it?
(if related to existing capability)

Current LexGrid model works well in biomedical and clinical community. It is important to leverage existing LexGrid model with Semantic Web tools and technologies.

6

If this requirement in met, what would be the benefits? If you do not have it, what would be the negative impact?
(prompt to elicit benefits/value - will help to prioritize)

This will improve the functionality and performance of the LexGrid. No negative impact.

7

If, for any reason, we were not able to create that solution, do you think there might be another way to solve this issue? Can you think of an alternative solution?
(prompt to elicit alternative solutions/workarounds)
(to be prepared by the Requirement Analyst)

Description of any other solution that customer can envision

8

Would you agree that we can summarize your requirement like this?
(Summarize one requirement in 2-3 lines and read back to interviewee for confirmation.)

The LexRDF model should translate the LexGrid model elements to corresponding constructs in W3C specifications. The terminological information represented in LexGrid should be translated into RDF triples. LexEVS should leverage the Semantic Web Tools (e.g., SPARQL) and technologies.

9

How important is this requirement to the interviewee? Required: Customer Priority/Annotationrement Analyst
(Provides concrete assessment of the relative importance for the requirements specification)

2. Should have

10

On a scale from 1 to 3 with 1 being "not satisfied" to 3 "completely satisfied", how would you rate your overall satisfaction with the product if this requirement was met?  (Relative rating/ranking of how satisfied or dissatisfied interviewee would be if this requirement were met/not met)

2. Mostly satisfied

11

Are there other requirements that you would like to share with us? I'd be more than happy to call you back another time, or if you have another 10 minutes, please share other issues you can think of.
(prompt to elicit any hidden - potentially higher priority requirements if they exist)

LexRDF approach focuses on translating (mapping) backend of the LexGrid from relational database to RDF triples. Eventually, we will leverage Semantic Web techniques with LexGrid loaders.

12

Who else should we talk to in order to elicit more information about this need?

N/A

 

For specific service enhancement or requirement from Forum entry:

---

13

Can you or someone else give me a step-by-step description of how you would describe the expected performance/behavior of the software in order for you to feel that your requirement is met? 
(Required: Fit Criterion - will help us create test cases and user acceptance criteria - to be prepared by the Requirement Analyst)

Well defined measurable verifiable expectation
