"The goal of Apache Marmotta is to provide an open implementation of a Linked Data Platform that can be used, extended and deployed easily by organizations who want to publish Linked Data or build custom applications on Linked Data."

"The VIAF™ (Virtual International Authority File) combines multiple name authority files into a single OCLC-hosted name authority service. The goal of the service is to lower the cost and increase the utility of library authority files by matching and linking widely-used authority files and making that information available on the Web."

"The Web is full of high-quality Linked Data. But we can't reliably query it. Public SPARQL endpoints are often unavailable, because they need to answer many unique queries."

"qLabel is a JavaScript library that helps you create multilingual websites. qLabel is Open Source and developed on GitHub. qLabel looks up and displays labels for entities marked up in a Website. In the next paragraph, click one of the languages, and you will see the display change accordingly."

"Wandora is a general purpose information extraction, management and publishing application based on Topic Maps and Java. Topic maps are hypergraphs with an emphasis on subjects. Wandora stores information in layered and auto-merging topic maps. Wandora has graphical user interface, multiple visualization models, huge collection of information extraction, import and export options, embedded HTTP server with several output modules and open plug-in architecture.

"This is a list of major active Open APIs, or Application programming interfaces, sets of technologies that enable applications to interact with each other."

"CHAIN-REDS is a FP7 project co-funded by the European Commission (DG CONNECT) aiming at promoting and supporting technological and scientific collaboration across different e-Infrastructures established and operated in various continents, in order to define a path towards a global e-Infrastructure ecosystem that will allow Virtual Research Communities (VRCs), research groups and even single researchers to access and efficiently use worldwide distributed resources (i.e., computing, storage, data, services, tools, applications)."

"EKOSS (Engineering/Environmental Knowledge Ontology-based Semantic Search) has been developed for sharing expert knowledge using semantic web technologies. The website provides a collaborative knowledge sharing environment where knowledge experts can submit advertisements of the knowledge resources that they have developed, such as research papers, databases and computer simulation models. "

"TRAVERSE THE GRAPH WITH OUR API MusicGraph is the world's first "natural graph" for music, which represents the real-world structure of the musical universe. Information contained within it includes data related to the relationship between millions of artists, albums, and songs. Also included is detailed acoustical and lyrical features, as well as real-time statistics across artists and their music across many sources. "

"MusicGraph is the world's first knowledge engine for music. It contains over a billion facts that have been organized into a rich music ontology, which includes acoustical and lyrical features, detailed artist, album and song information, as well hundreds of other data points related user preferences."

Stardog is an insanely fast, commercial RDF database: SPARQL for queries; OWL for reasoning; pure Java for the Enterprise.

"The Resource Description Framework (RDF) is a framework for representing information in the Web. This document defines an abstract syntax (a data model) which serves to link all RDF-based languages and specifications. The abstract syntax has two key data structures: RDF graphs are sets of subject-predicate-object triples, where the elements may be IRIs, blank nodes, or datatyped literals. They are used to express descriptions of resources. RDF datasets are used to organize collections of RDF graphs, and comprise a default graph and zero or more named graphs. RDF 1.1 Concepts and Abstract Syntax also introduces key concepts and terminology, and discusses datatyping and the handling of fragment identifiers in IRIs within RDF graphs."

"Develop the next generation of innovative apps IDOL OnDemand delivers a rich set of web service APIs to enable developers to create ground-breaking apps that tap into human information."

"DARPA Open Catalog, which contains a curated list of DARPA-sponsored software and peer-reviewed publications. DARPA funds fundamental and applied research in a variety of areas including data science, cyber, anomaly detection, etc., which may lead to experimental results and reusable technology designed to benefit multiple government domains. "

vocab.getty.edu contains open metadata for the Getty Vocabularies. The data is described semantically following linked data principles using the Resource Description Framework (RDF) format. This format enables direct access and use of Vocabulary data by computer applications.

"Libraries and their users are participating in an exciting information ecosystem."
