rdflib
Reference: https://rdrr.io/cran/rdflib/man/rdflib-package.html
This is an R package used to manipulate triples. Worth looking at how it specifies changes.
- add - rdf_add - could be used to express adding a triple
- delete - do not see a spec for removing a triple
rdf_add
Reference: https://rdrr.io/cran/rdflib/man/rdf_add.html
rdf_add could be used to specify adding a triple.
Example:
| Code Block | ||
|---|---|---|
| ||
rdf <- rdf()
rdf_add(rdf,
subject="http://www.dajobe.org/",
predicate="http://purl.org/dc/elements/1.1/language",
object="en")
## non-URI string in subject indicates a blank subject
## (prefixes to "_:b0")
rdf_add(rdf, "b0", "http://schema.org/jobTitle", "Professor")
## identically a blank subject.
## Note rdf is unchanged when we add the same triple twice.
rdf_add(rdf, "b0", "http://schema.org/jobTitle", "Professor",
subjectType = "blank")
## blank node with empty string creates a default blank node id
rdf_add(rdf, "", "http://schema.org/jobTitle", "Professor")
## Subject and Object both recognized as URI resources:
rdf_add(rdf,
"https://orcid.org/0000-0002-1642-628X",
"http://schema.org/homepage",
"http://carlboettiger.info")
## Force object to be literal, not URI resource
rdf_add(rdf,
"https://orcid.org/0000-0002-1642-628X",
"http://schema.org/homepage",
"http://carlboettiger.info",
objectType = "literal")
