M2RML: Multidimensional to RDF Mapping Language
Saleh Ghasemi, Wo-Shun Luk, Norah Alrayes · 2014
This research is about design and implementation of a middleware between an RDF application (as a client) and an OLAP server which manages multidimensional data. At the heart of the middleware is a software layer which accepts a query from the client and returns as the answer an RDF dataset. This software is an implementation of a mapping language from multidimensional data to RDF, or M2RML. The RDF dataset is a 'slice' of the data cube as defined in the W3C's RDF Data Cube Vocabulary. The limitations of the Data Cube Vocabulary are discussed, and options to overcome these limitations are proposed.
