In this paper, we present OPQL, an OPM-level provenance query language, that is directly defined over the Open Provenance Model (OPM). An OPQL query takes an OPM graph as input and produces an OPM graph as output.

2013年11月1日 · In this paper, we present OPQL, a provenance query language that enables the querying of provenance directly at the graph level. An OPQL query takes a provenance graph as input and produces another provenance graph as output. Therefore, OPQL queries are …

2011年7月4日 · In this paper, we present OPQL, an OPM-level provenance query language, that is directly defined over the Open Provenance Model (OPM). An OPQL query takes an OPM graph as input and produces an OPM graph as output.

nance storage strategies. In this paper, we present OPQL, an OPM-level provenance query language, that is directly defined over the Open Provenance Model (OPM). An OPQL query takes an OPM graph as input and produces an OPM graph as output. Therefore, OPQL queries are not tightly coupled to the underlying provenance storage strategies. Our main

2011年6月1日 · Our main contributions are: (i) we design an entity–relationship diagram for OPM and translate it into a relational database schema for the storage of provenance; (ii) we show that provenance reasoning defined in OPM (v1.1) can be sufficiently supported by OPMProv using recursive views and SQL queries alone without any additional reasoning engine.

Hadoop, and OPQL, a graph-level provenance query language, to build a scalable provenance storage and querying system for big data workflows. Our main contributions are: i) we propose algorithms to translate OPQL constructs to equivalent Pig Latin programs; ii) we extend OPQL, to support the W3C PROV-DM standard provenance model; iii) we ...

We finally propose OPQL, an OPM-level provenance query language, that is directly defined over the OPM model. An OPQL query takes an OPM graph as input and produces an OPM graph as output; therefore, OPQL queries are not tightly coupled to …
