Vladimir Alexiev created JENA-840:
-------------------------------------
Summary: riot is too permissive towards yearFrag of xsd:datetime
Key: JENA-840
URL: https://issues.apache.org/jira/browse/JENA-840
Project: Apache Jena
Issue Type: Bug
Components: RIOT
Affects Versions: Jena 2.12.2
Reporter: Vladimir Alexiev
I noticed that RIOT treats differently years in xsd:gYear & xsd:date vs
xsd:datetime. It's more permissive towards the yearFrag in xsd:datetime:
- allows leading +
- allows leading zeros even for >4 digits
So I checked [the
spec|http://www.w3.org/TR/xmlschema11-2/#rf-lexicalMappings-datetime] namely
D.2.1 The Seven-property Model and D.2.2 Lexical Mappings.
- the year component (yearFrag) is treated the same in all date & time datatypes
- it allows any number of digits, leading -, no leading +, and leading zeros
only up to 4 total digits:
{noformat}
[56] yearFrag ::= '-'? (([1-9] digit digit digit+)) | ('0' digit digit digit))
{noformat}
After playing with "riot --validate", I think it gets it right for gYear,
gYearMonth and date, but gets it wrong for datetime.
