Question

表达量我希望能够解答疑问，如“多少条记录被创建并LOG_ID 001”或“多少记录已被删除与属性‘00EA’。

34 records are created with attribute "00EC" and log_id "001" 
32 records are updated with attribute "00EC" and log_id "001" 
31 records are deleted with attribute "00EC" and log_id "001" 

12 records are created with attribute "00EA" and log_id "001" 
31 records are updated with attribute "00EA" and log_id "001" 
33 records are deleted with attribute "00EA" and log_id "001" 

9 records are created with attribute "00EB" and log_id "001" 
2 records are updated with attribute "00EB" and log_id "001" 
3 records are deleted with attribute "00EB" and log_id "001" 

19 records are created with attribute "00EA" and log_id "002" 
22 records are updated with attribute "00EA" and log_id "002" 
33 records are deleted with attribute "00EA" and log_id "002"

我想你得到的答案...

是相当不错的。添加的唯一的事情是，你拥有的数据是统计数据，因此它们可以表示为一个多维结构。一个好的本体代表这种类型的数据是SCOVO

所以这个记录的表示......

[] a :LogEvent; 
    :attribute "00EC"; 
    :log_id "001"; 
    :records_created 34; 
    :records_updated 32; 
    :records_deleted 31; 
    . 

可以与下面的架构级表示可以改善....

:LogEvent rdfs:subClassOf scovo:Item . 
:records_created rdfs:subPropertyOf scovo:Dimension . 
(...) 

此架构将“标记”您的数据增加关于谓词和类的额外知识。 随着您添加更多数据源到您的系统中，您将意识到在模式级别定义它对探索它非常有用。
