Schema

The figure above shows only the "standard" connections and a subset of the links in the ontology. You can discover these on your own by querying edges (predicates/links).

Links from strain

PREFIX f: <https://flu-crew.org/term/>

SELECT DISTINCT
    ?p  
WHERE {
    ?s f:host "swine" .
    ?s ?p ?o .
}   
LIMIT 30

This query finds all predicates that link from a swine strain node. It returns the following (sorted for reproducibility):

$ octofludb query 102.rq | sort

https://flu-crew.org/term/submission_date

Links from segment

This same approach can be used to find properties linking from segment nodes:

PREFIX f: <https://flu-crew.org/term/>

SELECT DISTINCT
    ?p  
WHERE {
    ?s f:host "swine" .
    ?s f:has_segment ?g .
    ?g ?p ?o .
}   
LIMIT 100

This returns:

Links from features

We can also pull out features, this is all information drawn directly from the GenBank feature tables.

PREFIX f: <https://flu-crew.org/term/>

SELECT DISTINCT
    ?p
WHERE {
    ?s f:host "swine" .
    ?s f:barcode ?barcode .
    FILTER REGEX(?barcode, "123") . # just to speed things up
    ?s f:has_segment ?g .
    ?g f:has_feature ?f .
    ?f ?p ?o .
}
LIMIT 100
