EMF-IncQuery presented at EclipseCon Europe 2011

Submitted by István Ráth on Sat, 12/10/2011 - 14:07

EMF-IncQuery was presented by István Ráth at EclipseCon Europe 2011, at the Modeling Symposium. We have talked about performance characteristics as well as presented our plans for the new architecture in the upcoming v0.7 release. More details about the symposium are found here.

Overview

About IncQuery Base

EMF-IncQuery Base aims to provide several useful (some would even argue critical) features for querying EMF models:

ECMFA2011: Incremental Evaluation of Model Queries over EMF Models: a Tutorial on EMF-IncQuery

This tutorial builds on the previous one at MODELS 2010, and presents the most up-to-date version of IncQuery, with detailed usage instructions and a case study. The full-fledged validation framework that we built on IncQuery technology is presented for the first time.

Query Language

Overview

Language concepts

For the query language, we reuse the concepts of graph patterns (which is a key concept in many graph transformation tools) as a concise and easy way to specify complex structural model queries. These graph-based queries can capture interrelated constellations of EMF objects, with the following benefits:

Q: What does EMF-IncQuery call the 'qualified name' of a graph pattern?

It is actually the fully qualified name, which is the qualified name of the containing package, a separator dot, and the simple name in the pattern (the one you define it with after the pattern keyword). The qualified name of the package has dot-separated segments, like in Java.

MODELS2010: Incremental Model Queries over EMF Models

In the MODELS2010 article Incremental Model Queries over EMF Models we introduced EMF-IncQuery, a framework for defining declarative queries over EMF models, and executing them efficiently without manual coding}. For the query language, we reuse the concepts of graph patterns as a concise and easy way to specify complex structural model queries. High runtime performance is achieved by adapting incremental graph pattern matching techniques. This webpage displays the technicalities of the case-study used in the paper.
