The first part of the Turtle data stream seems to contain syntax errors for some of the XSD decimal literals. The first one appears on line 13,291:
Notice that scientific notation is not allowed in the lexical form of decimals according to XML > Schema Part 2: Datatypes[https://www.w3.org/TR/xmlschema11-2/#decimal%5D.%C2%A0 (It is allowed in floats and doubles.) Is this a known issue or should I report this somewhere?
I wouldn't call these "syntax" errors, just "logical/type" errors. It would be great if these could fixed by changing the correct type from decimal to float/double. On the other hand, I've never seen any medium or large dataset without this kind of errors. So I would personally treat these as warnings at worst.
@Wouter when you build the HDT file, could you please also generate the .hdt.index file? With rdf2hdt, this should be activated with the -i flag. Thank you again!
