4store
4store is a database storage and query engine that holds RDF data. 4store's main strengths are its performance, scalability and stability. It does not provide many features over and above RDF storage and SPARQL queries, but if your are looking for a scalable, secure, fast and efficient RDF store, then 4store should be on your shortlist.
Dataquay
Dataquay is a library that provides a friendly C++ interface to an RDF datastore using Qt4 classes and containers. Supported datastores are the popular and feature-complete Redland and the lightweight Sord. It is principally aimed at Qt-based applications.
IceCat Heckert gnu.tiny.png
For WebExtensions, see FSD:IceCat WebExtensions (proposed)#Approved
GNU IceCat discontinued official IceCatMobile support after version 38.6.0. Unofficial IceCatMobile releases can be downloaded with the F-Droid client. GNU IceCat (originally GNU IceWeasel) is part of GNUzilla (the GNU version of the Mozilla Application Suite). GNU IceCat aim to be based on the the current official release of Firefox Extended Support Release (ESR) with removal of trademarked artwork and proprietary components. However, IceCat is not a straight fork of Firefox ESR; instead, it is a parallel effort that works closely with and re-bases in synchronization on the latest Firefox ESR as the upstream supplier, with patches merged upstream whenever possible; although it should be noted that additional security updates are customized to IceCat occasionally.

Differences between IceCat and Firefox ESR

Important differences between Mozilla's Firefox and GNU IceCat is that IceCat has a focus on freedom and privacy (see settings.js for details).

  • Encrypted Media Extensions (EME) is not implemented: Whereas Firefox are being created such that they support Digital Restrictions Management (DRM) systems through their implementation of the Encrypted Media Extension (EME), GNU IceCat doesn't include an EME implementation as it opposes efforts to popularize and ease the dissemination of DRM technology.
    • Widevine Content Decryption Module provided by Google Inc. is not installed in about:addons > Plugins
    • The Play DRM-controlled content option (used to download and enable Widevine Content Decryption Module provided by Google Inc.) has been removed from about:preferences > Content
  • WebRTC is enabled like in Firefox but prevent leaking the LAN ip. (Test WebRTC)
  • The proprietary program Mibbit has been removed.
  • Telemetry is disabled.
  • DuckDuckGo is the default search engine, which means that you can run "!Bangs" keywords in the location bar to use any search engine.

Philosophy

"We will always make IceCat block non-free JavaScript by default. If you want to permit nonfree software to run, you can easily disable LibreJS." - Richard Stallman

Customized add-ons

  • SpyBlock (Adblock Plus fork) to block privacy trackers.

History

GNU IceCat was formerly known as GNU IceWeasel but changed its name in 2008 to avoid confusion with Debian IceWeasel (who was rebranded back to Firefox in 2017 after Debian was being granted special permission from Mozilla)ref.

The GNU IceCat developers dropped support for Replicant after version 31.8.0 because these builds are already provided by F-Droid.

GNU IceCat developers dropped support for macOS, and Windows, after version 38.8.0 in 2016: "Note that building binary packages for Windows and macOS currently requires non-free software, so we no longer distribute binary releases for those platforms." - https://www.gnu.org/software/gnuzilla/

Infovore
Infovore is designed to merge large data sets such as Freebase and DBpedia, producing 100% valid RDF output at high speed because it uses the Hadoop Framework
Jpegrdf
'Jpegrdf' reads and manipulates RDF metadata stored in the comment section of JPEG images. It can extract, query, and augment the data. Manipulating JPEG images with jpegrdf does not modify the actual image data or any other sections of the file.
RDF
The packages is intended to provide the core RDF types and interfaces that other packages can build on. The package defines a plugin interface for parsers, stores, and serializers that other packages can use to implement parsers, stores, and serializers that will plug into the rdf package. The rdf package does not itself contain any plugin implementation. So, you will want to install a library that builds upon rdf and defines some plugin implementations.
Raptor RDF Parser Toolkit
'Raptor' is a library for parsing RDF syntaxes into RDF triples. It supports the latest W3C recommendation for RDF/XML including collections and datatypes, N-Triples, Turtle, and some XML RSS via a tag soup parser. It handles RDF/XML as used by RDF applications such as RSS 1.0, FOAF, Dublin Core, and OWL. It can use either expat or libxml2 for XML parsing, libcurl when available for URI retrieval, and is portable to many POSIX systems.
Rasqual
Rasqal is a C library for RDF (Resource Description Framework) query syntaxes, query construction and query execution returning result bindings. It supports the query languages RDQL and SPARQL. 'Rasqual' provides APIs for creating a query and parsing query synta. It includes pluggable triple-store source and matching interfaces, an engine for executing the queries and an API for manipulating results as bindings. It uses the Raptor RDF parser to return triples from RDF content and can also work with the Redland RDF library's persistent triple stores.
Tribler
It allows you to watch videos and download content. Tribler aims to combine the ease of Youtube.com with the performance of peer-to-peer. Tribler is backwards compatible with the BitTorrent download protocol. To discover interesting content standard RSS feeds with .torrent links are supported plus the "Tribe protocol" which automatically scans the network for available BitTorrent swarms upon startup. Tribler uses an embedded web browser to access video clips of Youtube.com and Liveleak.com. Other features are "People who like this also like" for recommending related swarms, the ability to make friends, and to donate idle upload capacity to friends. The later can improve download speed by a factor of two on asymmetric Internet links. The fastest way of social file sharing.
