CLucene is a high-performance, scalable, cross platform, full-featured indexing and searching API. It is a port of the very popular Java Lucene text search engine API to C++.

This package contains RDF Collections flattener for rdflib.

Python wrapper around a SPARQL service. It helps in creating the query URI and, possibly, convert the result into a more manageable format.

Lucene++ is an up to date C++ port of the popular Java Lucene library, a high-performance, full-featured text search engine.

Header Dictionary Triples (HDT) is a compression format for RDF data that can also be queried for Triple Patterns. This package provides a C++ library as well as various command-line tools to to work with HDT.

Rasqal is a C library that handles Resource Description Framework (RDF) query language syntaxes, query construction and execution of queries returning results as bindings, boolean, RDF graphs/triples or syntaxes. The supported query languages are SPARQL Query 1.0, SPARQL Query 1.1, SPARQL Update 1.1 (no executing) and the Experimental SPARQL extensions (LAQRS). Rasqal can write binding query results in the SPARQL XML, SPARQL JSON, CSV, TSV, HTML, ASCII tables, RDF/XML and Turtle/N3 and read them in SPARQL XML, RDF/XML and Turtle/N3.

The Redland RDF Library (librdf) provides the RDF API and triple stores.

This library can extract RDFa 1.1 from (X)HTML, SVG, or XML. It can produce serialized versions of the extracted graph, or an RDFLib Graph.

Raptor is a C library providing a set of parsers and serialisers that generate Resource Description Framework (RDF) triples by parsing syntaxes or serialise the triples into a syntax. The supported parsing syntaxes are RDF/XML, N-Quads, N-Triples 1.0 and 1.1, TRiG, Turtle 2008 and 2013, RDFa 1.0 and 1.1, RSS tag soup including all versions of RSS, Atom 1.0 and 0.3, GRDDL and microformats for HTML, XHTML and XML. The serialising syntaxes are RDF/XML (regular, abbreviated, XMP), Turtle 2013, N-Quads, N-Triples 1.1, Atom 1.0, RSS 1.0, GraphViz DOT, HTML and JSON.

RDFLib is a Python library for working with RDF, a simple yet powerful language for representing information.

LRDF is a library to make it easy to manipulate RDF files describing LADSPA plugins. It can also be used for general RDF manipulation. It can read RDF/XLM and N3 files and export N3 files, and it also has a light taxonomic inference capability.

Serd is a lightweight C library for RDF syntax which supports reading and writing Turtle and NTriples. Serd is not intended to be a swiss-army knife of RDF syntax, but rather is suited to resource limited or performance critical applications (e.g. converting many gigabytes of NTriples to Turtle), or situations where a simple reader/writer with minimal dependencies is ideal (e.g. in LV2 implementations or embedded applications).

re2c generates minimalistic hard-coded state machine (as opposed to full-featured table-based lexers). A flexible API allows generated code to be wired into virtually any environment. Instead of exposing a traditional yylex() style API, re2c exposes its internals. Be sure to take a look at the examples, as they cover a lot of real-world cases and shed some light on dark corners of the re2c API.

The GNU readline library allows users to edit command lines as they are typed in. It can maintain a searchable history of previously entered commands, letting you easily recall, edit and re-enter past commands. It features both Emacs-like and vi-like keybindings, making its usage comfortable for anyone.

Rlwrap is a 'readline wrapper', a small utility that uses the GNU readline library to allow the editing of keyboard input for any command. You should consider rlwrap especially when you need user-defined completion (by way of completion word lists) and persistent history, or if you want to program `special effects' using the filter mechanism.

RedNotebook is a modern desktop journal. It lets you format, tag and search your entries. You can also add pictures, links and customizable templates, spell check your notes, and export to plain text, HTML, Latex or PDF.

Superset of the POSIX regex API, enabling approximate matching. Also ships a version of the agrep utility which behaves similar to grep but features inexact matching.

RE2 is a fast, safe, thread-friendly alternative to backtracking regular expression engines like those used in PCRE, Perl and Python. It is a C++ library.

Fusion is a sensor fusion library implementing the Attitude and Heading Reference System (AHRS) algorithm, which combines available gyroscope, accelerometer, and magnetometer data into a single measurement of orientation relative to the Earth.

Enki is a robot simulator written in C++. It provides collision and limited physics support for robots evolving on a flat surface. On a contemporary desktop computer, Enki is able to simulate groups of robots hundred times faster than real-time.

AMD-specific device-side language runtime libraries, namely oclc, ocml, ockl, opencl, hip and hc.

The AMD SMI allows managing and monitoring AMD devices, particularly in high-performance computing environments. It provides a user-space interface that allows applications to control GPU operations, monitor performance, and retrieve information about the system's drivers and GPUs. It also provides a command-line tool, amd-smi, which can be used to do the same.
