Lack of whitespace following bracket character results in error

Created: 23/Aug/06 10:09 PM Updated: 05/Jul/07 11:13 AM

Component/s:

Turtle parser

Affects Version/s:

1.0.9, 1.0.8, 1.0.7, 1.0.6, 1.0.5, 1.0.4, 1.0.3, 1.0.2, 1.0.1

Fix Version/s:

1.0.10

Environment:

Sesame 2.0 alpha 3, recompiled for JRE1.4

Description

[:foo :bar;] throws an error while [ :foo :bar;] does not:

Fatal error: Expected an RDF value here, found ';' at (file) [(line number), -1]

The error varies according to whatever the parser concludes is happening when '[' is considered part of a character sequence. The Turtle EBNF appears to specify 0-or-more whitespace characters here:

blank ::= nodeID | '[]' | '[' ws* predicateObjectList ws* ']' | collection

Comment by Arjohn Kampman [24/Aug/06 10:37 AM]

The Turtle parser forgot to unread the character directly following the '[' character that was read to check for empty blank nodes ("[]").
