This page is for capturing the discussion around updating the workflow for value set definition creation.
Observations
- LexEVS model and implementation are more complex than requirements of most NCI value sets
- NCI Thesaurus may have enough assertions to adequately describe value sets without external modeling
Meeting Minutes
Value set requirements gathered through meetings with the NCI stakeholders. Minutes from the meetings are here:

...
- LexEVS model and implementation are more complex than requirements of most NCI value sets
- NCI Thesaurus may have enough assertions to adequately describe value sets without external modeling
- User needs beyond the browser should be recorded
- should include report writer
- excel spread sheet file consumers
- any users of value set definition and resolved value set XML files.
- consumers of the value set api
- Neoplasm value set types (containing self asserted hierarchy)
Proposed Support and Solutions
- Provide concurrent value set loading capability.
- Provide OWL export of value sets
- Provide programmatic Access to value set definition expressed as XML
- Provide examples for regular api level access of value set members
- Provide support for Neoplasm like value sets.
Requirements
Requirements for the new value set work flow architecture
...
| Proposed or Possible Requirement | Priority |
|---|---|
| Remove Dependency on Value Set Definitions for NCIt defined Value Sets | |
| Generate All NCIt sourced Value Sets from NCIt source. | |
| Resolve discrepancies between number of value set definition file set files and value sets defined in NCIt | |
| Provide acceptable substitutions for value set URI's and other metadata that is not defined in the source (List in other rows as necessary) | |
| Maintain Resolved Value Set Coding Scheme API as interface | |
Provide concurrent value set loading capability | |
Provide programmatic Access to value set definition XML files | |
Provide example code for regular api level access (CodedNodeGraph example) of value set members | |
Provide support for Neoplasm like value sets (Hierarchical) |
| Discussion Points | Notes |
|---|---|
| Who are the stakeholders and end users of value sets | |
| Define what end user interface is (Shell script, Rest Service, Browser based GUI) | |
Define performance or other considerations that require a move to triple store or OWL API (For Example: Do value sets need full OWL expressivity) | |
| Will non NCIt sourced value sets continue to use legacy value set definitions? (more a scope statement question) | |
| What considerations/requirements drive the development of an architecture that encompasses hierarchical value sets and new resolution mechanisms? | |
| Create OWL source for some/all values sets from LexEVS api or other source? (OWL export of value sets) | |
| What user needs around the report writer generate requirements for LexEVS or the LexEVS team | |
| Does Excel spread sheet generation fall into the scope of LexEVS value set resolution or otherwise generate requirements for the LexEVS team | |
| Do the users/stakeholders in the value set API have any new requirements beyond those already stated |
