Json-Lpg serialization for labeled property graphs

Abstract

Labeled Property Graphs (LPG) model applied to NoSQL graph databases has already attracted extensive attention since its remarkable performances on storage and query of graph-structure graphs. In addition, the data interchange based on LPG is increasing in the context of widely applications of Big Data. Hence, a serialization standard for LPG is urgently needed to meet the demand of growing LPG data exchange. This paper proposes a serialization standard called JSON-LPG that is fully compatible with JSON syntax. JSON-LPG provides a novel way to describe data type and shows better performance than conventional serialization formats of graph data. The proposed JSON-LPG not only easily integrates the systems that already use JSON, but also contributes to build interoperable Web applications by LPG data.
