有没有R2RML的Java开源实现? [英] Is there a Java open source implementation of R2RML?
问题描述
我想从表格数据生成RDF数据,特别是:CSV,TSV,电子表格(Excel或OpenOffice),最后是RDBMS中的表。
I want to generate RDF data from tabular data, in particular: CSV, TSV, spreadsheets (either Excel or OpenOffice) and, eventually, tables in RDBMS.
我知道RDB到RDF映射语言(R2RML)(http://www.w3.org/TR/r2rml/)当前草案。
I am aware of the "RDB to RDF Mapping Language" (R2RML) (http://www.w3.org/TR/r2rml/) current draft.
I使用Apache Jena处理,存储和查询RDF数据和/或读取CSV或TSV文件。我使用Apache POI来阅读Microsoft Excel电子表格,我计划使用Apache ODF Toolkit来阅读OpenOffice电子表格。
I use Apache Jena for processing, storing and querying RDF data and/or reading CSV or TSV files. I use Apache POI for reading Microsoft Excel spreadsheets and I am planning to use Apache ODF Toolkit for reading OpenOffice spreadsheets.
有一个Java开源(最好是ASL)实现R2RML我可以使用?
Is there a Java open source (preferably ASL) implementation of R2RML I can use?
推荐答案
D2RQ 是受欢迎的 D2R服务器背后的实现。开源(Apache)和用Java编写,所以我想这是你需要的。
D2RQ is the underling implementation behind the popular D2R Server. Open source (Apache) and written in Java, so I guess it's exactly what you need.
