Getting duplicate record with just different ULAN ID

[Hungry Shark]

select * {?c foaf:focus [a schema:'Person']}

Example Data:

I was able to get 2 records by running the code above for Štrukelj, Vojka, with ULAN IDs: 500278870 & 500278869
I searched the ID from Getty(http://www.getty.edu/research/tools/vocabularies/ulan/), I am getting the correct name for 500278870 but different name for 500278869 (Tomšič, Ricardo M.)

How can I correct my query? And can someone explain why from query, both ids pointing to same name but in Getty, they are pointing to different name?

Thanks in advance!

Your query is invalid: I get error Encountered " "\'Person\' "" at line 3, column 35.

This corrected query returns 100 ULAN IDs as expected:

select * {?c foaf:focus [a schema:Person]} limit 100

Finally, this query returns the two names you mentioned, relating to two ULAN IDs:

select * {

  values ?id {"500278870" "500278869"}

  ?c foaf:focus [a schema:Person]; dc:identifier ?id; gvp:prefLabelGVP/xl:literalForm ?name  

} limit 100

Can you tell us what you're trying to do, and the exact query that is problematic?
