Hi David, Thank you for your reply! But I still have questions. I want to know more information about the sequence about load data query. For example, as the normal process, a RDF file named rdf.nt load into Rya, first, A.class get the data, B.class handle the data as the predefined index structure, and C.class load data into Accumulo. For a query, 1.class get the query instance, 2.class parse statement, 3.class connect to Accumulo and obtain the data. There are so many similar files and classes in Rya-project, so I will be confused, I don't know which one is core and effective. I can't know in real time which class to call when performing an operation. My question looks stupid, so please forgive me.
