All these exercises are intended to guide you through retrieving SNOMED CT content. However, if you have applications/code where the results of queries can be directly used, you are likely to get more benefit from the exercises. And of course, you can retrieve other content that is not necessarily specified here.
For these exercises, participants can access one of 3 servers:
- https://snowstorm-fhir.snomedtools.org/fhir/ (this is a read-only instance)
- https://snowstorm-devdays.snomedtools.org/fhir/ (this is a temporary read/write instance)
- Follow instructions at https://github.com/IHTSDO/snowstorm/blob/master/docs/getting-started.md to install a local instance of Snowstorm and load an edition of SNOMED CT.
Exercise #1 - Simple Content Retrieval
- Discover the capabilities of SNOMED International Snowstorm terminology server
- Retrieve the information for the concept with the following SNOMED CT identifier, 82272006 | Common cold (disorder)| .
- Retrieve the information for the concept with the following SNOMED CT identifier, 82272006 | Common cold (disorder)| in Spanish
- Retrieve the normal form for the concept with the following SNOMED CT identifier, 22298006 | Myocardial infarction (disorder)| .
Exercise #2 - Content Searching
- Retrieve all types of cancer
- Retrieve all concepts related to asthma, returning results in Spanish
Find the ICD-10 map targets for 9977002 | Blister of ankle with infection (disorder)|
Exercise #3 - Advanced querying with ECL and implicit Valuesets
Create ECL queries to retrieve the following results:
- Find all the concepts that are members of the 450970008 | General Practice / Family Practice reference set (foundation metadata concept)|
- Find all the concepts that are members of the General Practice / Family Practice reference set and are a type of 125605004 | Fracture of bone (disorder)|
- Find all the concepts that are respiratory disorders due to an allergic reaction to pollen
Exercise #4 - Creating value sets
- Using the caffeine-products.json file below as an example (or use your own JSON file), create a new value set, making sure you change the identifier in the file and give it a unique identifier such as <yourname-domain>
- curl -i --request PUT "https://snowstorm-devdays.snomedtools.org/fhir/ValueSet/caffeine-products" --header "Content-Type: application/fhir+json" -d @caffeine-products.json
- Retrieve the previously created value set
- Use the expand operation on the value set containing ECL as well as filter parameters
- Add some new items to the value set by updating the JSON file
example file #1: caffeine-products.json
