11:35:01 ^Jenny^: hmm

11:35:05 ^Jenny^: whats wrong with this query:

11:35:07 ^Jenny^: DELETE FROM <http://faui8185.informatik.uni-erlangen.de/examples/BIODATModellierung/biodat_5_owl-dl.owl> WHERE { <http://www8.informatik.uni-erlangen.de/IMMD8/Services/cidoc-crm/mapping/biodat/biodat_5_owl-dl.owl#Taxonomic_Name_of_Beech_leaf01> <http://www8.informatik.uni-erlangen.de/IMMD8/Services/cidoc-crm/mapping/biodat/biodat_5_owl-dl.owl#P3.has_note> <http://www8.informatik.uni-erlangen.de/IMMD8/Services/cidoc-crm/mapping/biodat/biodat_5_owl-dl.owl#empty_

11:35:23 ^Jenny^: the WHERE is too much?

11:35:54 bengee: a WHERE defines the delete pattern (which is missing in your query)

11:36:08 bengee: i.e. either DELETE FROM <graph>

11:36:24 ^Jenny^: it is DELETE FROM <graph>

11:36:59 bengee: or DELETE FROM <graph> { ?s ?p ?o } WHERE {?s ?p ?o}

11:37:27 ^Jenny^: ah

11:37:40 ^Jenny^: in my case I know the three parts of the triple

11:37:58 bengee: so, in your case: DELETE FROM <graph> { <subject> <predicate> <object>}

11:38:01 ^Jenny^: so it is DELETE FROM <graph> { <bla> <bli> <blo> } ?

11:38:05 ^Jenny^: ok, thanks :)

11:40:28 bengee: arc's DELETE is based on CONSTRUCT, the full query pattern is DELETE FROM <graph> CONSTRUCT { constructTemplate} FROM <constructDataset> WHERE {selectPatterns}

11:40:44 bengee: and CONSTRUCT can be omitted

11:40:46 ^Jenny^: ah, ok :)

11:41:14 ^Jenny^: can I omit the graph?

11:42:03 bengee: not the first one

11:42:12 ^Jenny^: hm

11:42:38 ^Jenny^: whats the graph name after query('load http://path-to-ontology/ont.owl') ?

11:42:52 bengee: should be the same

11:43:00 ^Jenny^: http://path-to-ontology/ont.owl then?

11:43:04 bengee: yes

11:43:17 bengee: not 100% sure about redirects

11:43:26 ^Jenny^: hm, why the heck doesn't it delete then :/
