Jailer is a database subsetting and browsing tool. It is a tool for data exporting, schema browsing, and rendering. It exports consistent, referentially intact row-sets from relational databases. It removes obsolete data without violating integrity. It is DBMS agnostic (by using JDBC), platform independent, and generates DbUnit datasets, hierarchically structured XML, and topologically sorted SQL-DML.
DKPro WSD provides UIMA components which encapsulate corpus readers, linguistic annotators, lexical semantic resources, WSD algorithms, and evaluation and reporting tools. You configure the components, or write new ones, and arrange them into a data processing pipeline. DKPro WSD is modular and flexible. Components which provide the same functionality can be freely swapped. You can easily run the same algorithm on different data sets, or test several different algorithms on the same data set.
Meson aims to be the most usable and fast build system. It provides a simple yet powerful mostly declarative language for describing your build. It has native support for modern tools and frameworks, such as Qt5, code coverage, unit tests, precompiled headers, and others. It utilizes a host of optimization techniques to compile your code faster on both full and incremental builds.

You can traverse entire or parts of trees and graphs of records in a few milliseconds. It supports schema-less, schema-full, and schema-mixed modes, has a strong security profiling system based on users and roles, and supports SQL between the query languages. Thanks to the SQL layer, it's straightforward to use for people skilled in the relational world.
