N-Triples files aren't read if blank node label starts withnumber #5

Open retog opened 8 years ago

_:1 <http://example.org/p> "o".

the blank node identifier seems legal as https://www.w3.org/TR/n-triples/ says: "The characters _ and [0-9] may appear anywhere in a blank node label."

But inserting that in blazegrah results in:

@retog Would you mind creating a JIRA ticket for this one?

retog commented 8 years ago

@beebs-systap. ok I signed up, went through the 12 jira introduction points I couldn't skip. Created the issue https://jira.blazegraph.com/browse/BLZG-1920 then I tried to edit it again to fix the unsupported formatting, but I might not have payed enough attention with the JIRA introduction.

Why can't we just agree on a bug ontology and publish issues as linked data?

beebs-systap commented 8 years ago

Thx! Agreed on the issues as linked data...someday... 👍
