getting rdf xml:attribute in sparql query -

-

given rdf:

<?xml version="1.0" encoding="utf-8"?> <!doctype rdf:rdf [<!entity rdf 'http://www.w3.org/1999/02/22-rdf-syntax-ns#'> <!entity rdfs 'http://www.w3.org/2000/01/rdf-schema#'> <!entity xsd 'http://www.w3.org/2001/xmlschema#'>]> <rdf:rdf xmlns:xsd="http://www.w3.org/2001/xmlschema#"           xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#"          xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"      xmlns:dnr="http://www.dotnetrdf.org/configuration#"          xml:base="http://www.example.org/">  <rdf:description rdf:about="fadi">         <ns:be xmlns:ns="http://example.org/">nice</ns:be>       </rdf:description>  <rdf:description rdf:about="fadi">     <ns:not xmlns:ns="http://example.org/" xml:starttime="00:00:13" xml:endtime="00:00:16">good</ns:not>     </rdf:description>  <rdf:description rdf:about="she">     <ns:be xmlns:ns="http://example.org/" xml:starttime="00:00:13" xml:endtime="00:00:16">good</ns:be>     </rdf:description>     </rdf:rdf>

how can attributes: starttime , endtime, sparql query request?!

you can't, using xml namespace in way attributes means attributes silently ignored rdf/xml parser don't generate triples.

from rdf/xml specification section 6:

element information items reserved xml names (see name in xml 1.0) not mapped data model element events. these property [prefix] beginning xml (case independent comparison) , [prefix] property having no value , have [local name] beginning xml (case independent comparison).

therefore cannot retrieve data because doesn't exist far rdf/xml system concerned.

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
