Extract Data from a File

To extract data from a file, follow the steps in the previous section for getting a token with the data:read and data:write scopes, encoding the urn of the file using the jsonlite::base64_enc() function, and translating the file into SVF format using the translateSvf() function. Next, retrieve metadata for a file using the getMetadata() function, which returns an object with the type, name, and guid of the file. Note the guid and store it in .Renviron.

resp <- getMetadata(urn = myEncodedUrn, token = myToken)
myGuid <- resp$content$data$metadata[[1]]$guid

To get the object tree of a model, use the getObjectTree() function.

resp <- getObjectTree(guid = myGuid, urn = myEncodedUrn, token = myToken)
resp
