hWriteRdf reverses node text about rdf4h HOT 3 CLOSED

Thanks for raising this. Would you mind providing a very small test case showing an example where hWriteRdf does this, please? I'll try fix this soon after. Thanks!

Thanks for the quick reply. Here's a test case:

{-# LANGUAGE OverloadedStrings #-}

import Data.Text as T

import Data.RDF
import Data.RDF.Namespace

globalPrefix :: PrefixMappings
globalPrefix = ns_mappings []

baseURL :: Maybe BaseUrl
baseURL = Just $ BaseUrl "file://"

testURL = "file:///this/is/not/a/palindrome"

tris :: [Triple]
tris = [Triple
       (unode testURL)
       (unode testURL)
       (LNode . PlainL . T.pack $ "literal string")]

testRdf :: TriplesGraph
testRdf = mkRdf tris baseURL globalPrefix

main :: IO ()
main = writeRdf NTriplesSerializer testRdf

I expect

<file:///this/is/not/a/palindrome>  <file:///this/is/not/a/palindrome> "literal string" .

<emordnilap/a/ton/si/siht///:elif> <emordnilap/a/ton/si/siht///:elif> "literal string" .

I'm using rdf4h-1.1.0 and ghc-7.6.2. Incidentally, the Show instance is right-ordered:

Triple(UNode("file:///this/is/not/a/palindrome"),UNode("file:///this/is/not/a/palindrome"),LNode(PlainL(literal string)))

Thanks again @bergey , and apologies for the delay in responding. I added your report as a test case here . It confirmed you bug report, which has now been fixed in 0cc25b8 . Please let me know if you find anything else!
